Collect Documents From Users Through A Chatbot

The Conferbot API is a RESTful interface that lets your chatbot communicate with external systems, databases, and services in real time during conversations. Instead of limiting your chatbot to static, scripted responses, API integration transforms it into a dynamic assistant that can check order status from Shopify, pull customer records from Salesforce, schedule appointments in Google Calendar, process payments through Stripe, and trigger workflows in any system with an HTTP endpoint. According to MuleSoft's 2024 Connectivity Benchmark, the average enterprise uses 1,061 applications yet only 29% are integrated -- a chatbot with API access becomes a single conversational interface to this otherwise fragmented tech stack.

What API Integration Enables

Without API integration, a chatbot can only respond with pre-written text. With API integration, it becomes a transactional interface:

• Data retrieval: "What's my order status?" -- chatbot queries your order management API and returns real-time tracking info
• Data creation: "Book me an appointment for Tuesday at 2pm" -- chatbot creates a calendar event via API and confirms with the user
• Data updates: "Change my shipping address" -- chatbot updates the customer record in your CRM
• Workflow triggers: "I need to return this item" -- chatbot initiates a return workflow, generates a shipping label, and sends it to the customer
• Calculations: "How much will shipping cost to France?" -- chatbot queries shipping rate API with package details and returns exact pricing

Two Integration Approaches

Conferbot supports two approaches to API integration. The visual approach uses the no-code builder where you configure API calls through a point-and-click interface -- define the endpoint, map chatbot variables to parameters, and specify how to display the response. No coding required. The developer approach uses Conferbot's outbound API configuration with full control over headers, authentication, request bodies, and response parsing logic. Both approaches support the same capabilities; the choice depends on your team's technical comfort level.

For teams that need even simpler connectivity, Conferbot integrates with Zapier and Make (Integromat) for access to 5,000+ pre-built integrations with zero code. Our API integration guide walks through real examples. Use the ROI calculator to model how API-powered dynamic conversations improve conversion and support deflection rates.

Conferbot's API integration supports the full spectrum of REST API interactions. You can call any publicly accessible HTTP endpoint from within your chatbot conversation flows, with complete control over the request method, headers, body, and response parsing. This section covers the technical details of how API calls are configured and executed.

Supported HTTP Methods

• GET: Retrieve data from external systems (order status, account details, product info, weather, stock prices)
• POST: Create new records (book appointment, submit form, create ticket, initiate payment)
• PUT/PATCH: Update existing records (change address, update preferences, modify booking)
• DELETE: Remove records (cancel appointment, unsubscribe, delete saved item)

Request Configuration

Each API call in Conferbot is configured with:

• Endpoint URL: The full URL with support for dynamic path parameters (e.g., /api/orders/{orderId} where orderId comes from the conversation)
• Headers: Custom headers including Content-Type, Authorization, and any vendor-specific headers
• Query parameters: Key-value pairs appended to the URL, mapped from chatbot variables
• Request body: JSON body for POST/PUT requests with template variables from the conversation (customer name, email, selections)
• Timeout: Configurable per-call timeout (default 10 seconds) with custom fallback messages

Response Handling

API responses are parsed using JSONPath expressions that extract specific fields from the response:

• Simple extraction: `$.data.status` gets the order status field
• Array handling: `$.data.items[*].name` extracts all item names from a list
• Conditional display: Show different messages based on response values (e.g., if status is "shipped" show tracking link, if "processing" show estimated date)
• Error handling: Custom messages for 4xx/5xx responses, network timeouts, and malformed responses

The visual builder shows a live preview of how API responses will appear in the chat, including formatting, links, and media attachments. For complex response structures, you can use multiple JSONPath extractions to build rich response messages that combine data from different fields. See our builder documentation for detailed configuration examples.

Security is paramount when your chatbot communicates with external systems that contain sensitive customer data, financial records, or operational controls. Conferbot supports multiple authentication methods to match whatever your target API requires, with all credentials stored encrypted at rest and never exposed in client-side code or conversation logs.

Supported Authentication Methods

1. API Key Authentication: The simplest and most common method. Your API key is included as a header (X-API-Key, Authorization: ApiKey xxx) or query parameter on every request. Conferbot stores the key encrypted and injects it at request time -- it never appears in conversation data or browser-accessible code. Supported by: most SaaS APIs, Google services, weather APIs, shipping calculators.

2. OAuth 2.0: The industry standard for delegated authorization. Conferbot handles the full OAuth flow: authorization code grant, token exchange, token storage, and automatic refresh when tokens expire. This is required for APIs that access user-specific data (Google Calendar, Microsoft 365, Salesforce, HubSpot). The OAuth configuration includes: authorization URL, token URL, client ID, client secret, scopes, and redirect URI.

3. Bearer Token (JWT): Used by APIs that issue JSON Web Tokens after initial authentication. Conferbot can either use a pre-generated long-lived token or call an authentication endpoint to obtain fresh tokens before each API call. Tokens are automatically refreshed based on expiration time.

4. Basic Authentication: Username and password encoded in the Authorization header. While less common in modern APIs, some legacy systems and internal endpoints still require Basic auth. Conferbot encodes credentials automatically.

5. Custom Headers: For APIs with proprietary authentication schemes, you can define arbitrary headers with static or dynamic values. This covers vendor-specific patterns like Shopify's X-Shopify-Access-Token or Twilio's Account SID + Auth Token combination.

Security Best Practices

• All credentials encrypted at rest using AES-256 encryption
• Credentials never logged in conversation transcripts or analytics
• IP whitelisting available for APIs that support it (configure Conferbot's static IP ranges)
• Per-integration audit logging shows when credentials were used and by which chatbot
• Team permissions control who can view/edit API configurations

For enterprise deployments with strict security requirements, Conferbot supports credential rotation reminders, integration health monitoring, and automatic disabling of integrations that return repeated authentication failures. Learn more about security in our privacy and compliance documentation, or compare authentication support across chatbot platforms.

While REST API calls are initiated by the chatbot during conversations (outbound requests), webhooks enable the reverse pattern: external systems triggering chatbot actions based on events (inbound signals). This bidirectional communication makes your chatbot a true participant in your operational workflow rather than a passive responder. Webhooks are the foundation of event-driven chatbot architectures that react to real-world events in real time.

Inbound Webhooks: External Events Triggering Chatbot Actions

Configure Conferbot to receive webhook notifications from external systems. When an event fires, the chatbot can automatically initiate a conversation, send a message, or trigger a flow:

• New CRM lead: When a lead is created in Salesforce/HubSpot, the chatbot sends a personalized welcome message on WhatsApp or Messenger within seconds
• Order shipped: When your fulfillment system marks an order as shipped, the chatbot notifies the customer with tracking details
• Appointment reminder: Calendar system fires a webhook 24 hours before appointment, chatbot sends a confirmation request
• Payment received: Stripe webhook triggers a thank-you message with receipt and next-steps information
• Support ticket update: When a ticket status changes, notify the customer via their preferred channel

Outbound Webhooks: Chatbot Events Triggering External Actions

Configure the chatbot to send webhook notifications when specific conversation events occur:

• Lead captured: When a visitor provides their email/phone, notify your CRM, email marketing tool, and sales team simultaneously
• Appointment booked: Create calendar events, send confirmation emails, update availability
• Support ticket created: Notify helpdesk, assign to agent, start SLA timer
• Survey completed: Push CSAT/NPS scores to your analytics platform
• Escalation triggered: Alert human agents via Slack/Teams when AI cannot resolve

Webhook Configuration

Each webhook includes: endpoint URL, HTTP method, custom headers, payload template with conversation variables, retry logic (3 retries with exponential backoff), and failure handling (alternative action if webhook fails). Webhook payloads are signed with HMAC-SHA256 so receiving systems can verify authenticity. All webhook activity is logged with full request/response details for debugging.

Webhooks combined with the omnichannel deployment mean that external events can trigger chatbot responses on any channel -- a CRM event fires a WhatsApp message, a shipping update triggers an in-app notification via mobile SDK, or a calendar reminder sends a Telegram message. Browse templates with pre-configured webhook integrations for common use cases.

A chatbot is only as good as its data. If a customer asks "what's my account balance?" and the chatbot returns yesterday's data, the experience breaks trust. Data synchronization ensures that the information your chatbot accesses and presents is always current, accurate, and consistent with the source of truth in your external systems.

Real-Time Sync (API Call Per Request)

For data that changes frequently or where freshness is critical (account balances, inventory counts, order status), the chatbot makes a live API call at the moment the user asks. This guarantees accuracy at the cost of adding 200-500ms latency per query. Conferbot caches nothing by default for these calls -- every request hits the source system. This is the right approach for: financial data, inventory availability, shipping status, appointment availability, and any data that could change between page loads.

Scheduled Sync (Periodic Bulk Updates)

For data that changes infrequently (product catalogs, pricing tables, office locations, staff directories), scheduled sync pulls updated data at configurable intervals (hourly, daily, weekly) and stores it locally for instant chatbot access. This eliminates API latency for stable data and reduces load on source systems. The chatbot responds instantly from cached data while background processes keep it fresh.

Event-Driven Sync (Webhook-Triggered Updates)

The most efficient pattern for data that changes unpredictably. External systems send a webhook when data changes, and the chatbot updates its local cache immediately. For example: when a product price changes in your e-commerce platform, a webhook notifies Conferbot, and the updated price is immediately available for chatbot responses. No polling overhead, no stale data, no latency penalty for users.

Conflict Resolution

When data flows in both directions (chatbot updates CRM, CRM updates chatbot), conflicts can arise. Conferbot uses a "last write wins" strategy by default with configurable override rules. For critical data, you can configure the chatbot to always defer to the source system (read-only mode) or always push changes to the source (write-through mode).

• Real-time sync: 200-500ms latency, always fresh, best for volatile data
• Scheduled sync: instant response, updated hourly/daily, best for stable catalogs
• Event-driven sync: instant response, updated on change, best balance of speed and freshness
• Hybrid approach: combine all three for different data types within the same chatbot

Data sync configuration is managed through the same visual builder interface where you design conversation flows. Each API integration can be configured with its sync strategy independently. Monitor sync health in the analytics dashboard which shows API response times, error rates, and cache hit ratios.

Production chatbot API integrations must handle failure gracefully. External APIs go down, rate limits are hit, network connections drop, and responses sometimes return unexpected formats. A chatbot that shows users raw error messages or freezes mid-conversation destroys trust. Conferbot implements comprehensive error handling at every layer to ensure conversations continue smoothly even when APIs misbehave.

Rate Limiting

Most APIs enforce rate limits (e.g., 100 requests/minute for free tiers, 1,000/minute for paid plans). Conferbot tracks rate limit headers (X-RateLimit-Remaining, Retry-After) from each API and implements intelligent throttling:

• Preemptive throttling: When approaching limits (below 20% remaining), the system queues requests and processes them within the rate window
• Backoff and retry: When limits are hit (429 response), automatic exponential backoff with configurable retry count (default: 3 retries)
• Fallback responses: While waiting for rate limit reset, the chatbot provides helpful alternatives ("I'm checking that for you -- it may take a moment")
• Cross-conversation deduplication: If 10 users ask the same question within seconds, the system makes one API call and shares the result

Error Handling Strategies

For each API integration, you configure error handling behavior at three levels:

Level 1: Retry (transient errors): For 5xx errors, timeouts, and network failures, the system retries up to 3 times with exponential backoff (1s, 2s, 4s). Most transient errors resolve within the retry window without the user noticing any delay.

Level 2: Fallback response (persistent errors): When retries fail, the chatbot delivers a pre-configured fallback message. Instead of "Error: API returned 500," the user sees: "I'm having trouble looking that up right now. Would you like me to connect you with a team member, or can I help with something else?"

Level 3: Alternative path (critical failures): For integrations where the API is the core value (e.g., order lookup), you can configure alternative conversation paths: collect the customer's email and send the information later, offer to create a callback request, or escalate to a human agent via live chat.

Monitoring and Alerts

The analytics dashboard includes an API Health section showing: success rates per integration, average response times, error frequency and types, rate limit utilization, and trend analysis. Configure email or Slack alerts when error rates exceed thresholds, so your team can address issues before they impact customer experience at scale.

Robust error handling is what separates production chatbot deployments from demos. All paid plans include full error handling configuration. See how reliability features compare across platforms on our comparison page.

Beyond the visual API configuration in the dashboard, Conferbot provides programmatic access through SDKs and client libraries for teams that prefer code-first integration or need to build custom automation around their chatbot. These libraries handle authentication, request signing, error handling, and response parsing automatically, letting developers focus on business logic rather than HTTP plumbing.

Available Libraries

• JavaScript/Node.js: `npm install @conferbot/sdk` -- Full API coverage with TypeScript definitions, async/await patterns, and built-in retry logic. Works in Node.js backends, serverless functions (AWS Lambda, Vercel), and edge workers.
• Python: `pip install conferbot` -- Pythonic interface with dataclass models, async support via httpx, and integration with popular frameworks (Flask, FastAPI, Django).
• REST API (language-agnostic): Full OpenAPI 3.0 specification available for generating clients in any language. Use with Go, Java, Ruby, PHP, or any HTTP-capable environment.
• Zapier: No-code integration with 5,000+ apps. Triggers fire on conversation events; actions send messages or update chatbot data.
• Make (Integromat): Visual workflow builder with Conferbot modules for complex multi-step automations.

Common SDK Use Cases

Developers use the SDK to build functionality beyond what the visual builder provides:

• Custom analytics pipelines: Stream conversation events to your data warehouse (BigQuery, Snowflake, Redshift) for advanced analysis
• Dynamic flow updates: Programmatically update chatbot responses based on external triggers (e.g., update pricing when your catalog changes)
• Bulk operations: Create/update/delete conversations, contacts, or chatbot configurations across many bots simultaneously
• Testing automation: Write automated tests that simulate conversations and verify API integrations work correctly
• Custom dashboards: Pull chatbot analytics data into your own reporting tools or client portals

API Rate Limits for SDK Usage

All SDKs include comprehensive documentation with code examples, quick-start guides, and integration recipes. The JavaScript SDK includes a CLI tool for testing API calls from your terminal. See pricing details for API limits per plan, or explore the mobile SDKs for native app integration.

API integration transforms chatbots from information kiosks into transactional interfaces. The following use cases demonstrate how Conferbot customers connect their bots to external systems across different industries, showing the specific APIs involved, the conversation flows enabled, and the business results achieved.

E-Commerce: Order Management

A Shopify store connects their chatbot to the Shopify Orders API and ShipStation tracking API. Customers type "where's my order?" and the chatbot asks for their email, queries the order API, and returns real-time shipping status with tracking links. Results: 73% of order status queries resolved without human involvement, average response time reduced from 4 hours (email) to 3 seconds. The same chatbot handles returns by creating return labels via the Shippo API and sending them directly in the chat.

Healthcare: Appointment Scheduling

A dental practice connects to their practice management system (Dentrix) API and Google Calendar. Patients can book, reschedule, or cancel appointments entirely through the chatbot on their WhatsApp channel. The chatbot checks real-time availability, handles provider preferences, and sends confirmation with calendar invites. Results: 45% of appointments now booked via chatbot (previously all phone calls), no-show rate decreased 28% due to automated WhatsApp reminders.

Real Estate: Property Search

A real estate brokerage connects their chatbot to MLS (Multiple Listing Service) API. Buyers describe what they want ("3 bedroom house under $500K in Austin with a pool") and the chatbot queries the MLS API with extracted criteria, returning matching listings with photos, prices, and scheduling links for viewings. Integrated with Google Calendar API for instant showing bookings and DocuSign API for digital offer submissions.

SaaS: Account Management

A B2B SaaS company connects their chatbot to Stripe (billing), their own product API (usage data), and Salesforce (account records). Customers can check their current plan usage, upgrade/downgrade subscriptions, download invoices, and get usage-based recommendations -- all without logging into the product or contacting support. Connected via AI agent for complex billing questions that go beyond simple lookups.

Financial Services: Account Inquiries

A digital bank connects to their core banking API (behind a secure gateway). Customers check balances, view recent transactions, freeze/unfreeze cards, and set up direct debits through the chatbot. OAuth 2.0 ensures proper authorization, and biometric verification via mobile SDK adds a security layer for sensitive operations.

Each of these integrations was configured without custom backend code using Conferbot's visual API builder. Explore industry templates with pre-configured integrations, or use the ROI calculator to model the impact for your specific use case.

This quick-start guide walks you through connecting your first external API to a Conferbot chatbot. We will build a practical example: a chatbot that checks real-time weather data for any city using the OpenWeatherMap API. The same patterns apply to any REST API -- CRM lookups, payment processing, booking systems, or custom backends.

Step 1: Create Your API Connection (3 minutes)

In your Conferbot dashboard, navigate to Integrations > API Connections > Add New. Enter the following:

• Name: Weather API
• Base URL: https://api.openweathermap.org/data/2.5
• Authentication: API Key (query parameter: appid)
• API Key: [your OpenWeatherMap API key]

Step 2: Configure the API Call (5 minutes)

Create a new API action within your chatbot flow:

• Endpoint: /weather
• Method: GET
• Parameters: q = {city_name} (mapped from chatbot variable), units = metric
• Response mapping: temperature = $.main.temp, description = $.weather[0].description, humidity = $.main.humidity
• Timeout: 5 seconds
• Fallback message: "Sorry, I couldn't check the weather right now. Try again in a moment."

Step 3: Build the Conversation Flow (5 minutes)

In the visual builder, create a flow:

• User says: "What's the weather in [city]?"
• Bot extracts city name into variable {city_name}
• Bot triggers Weather API call
• Bot responds: "The weather in {city_name} is {description} with a temperature of {temperature}C and {humidity}% humidity."

Step 4: Test and Deploy (2 minutes)

Use the built-in API tester to verify your endpoint returns data correctly. Test with different city names to confirm error handling works for invalid inputs. Once satisfied, publish your chatbot -- the API integration is live immediately across all connected channels.

Next Steps

With the basic pattern established, you can extend to more complex integrations:

• Add CRM lookups: replace weather API with Salesforce/HubSpot contact queries
• Add transactional APIs: POST requests to create appointments, orders, or tickets
• Chain multiple APIs: query one system, use the result to query another
• Add conditional logic: different API calls based on user segment or conversation path
• Connect webhooks: trigger proactive messages based on external events
