# Chatway Developer Documentation > Official developer documentation for Chatway, a customer communication platform for live chat, messaging, customer support, and AI-powered support workflows. Use Chatway's REST API and Webhooks to access conversations, contacts, messages, agents, widgets, and real-time events.

API base URL: https://developers.chatway.app/api/v1 Authentication uses an API key passed in the `X-API-KEY` HTTP header. The API can be used to: - List Chatway widgets - Retrieve contacts - Create and update contacts - Initialize visitor contacts - Retrieve conversations - Read conversation messages - Send messages to conversations - Resolve conversations - Retrieve agents - Invite agents - Build custom integrations - Synchronize Chatway with CRMs and external systems - Build automated customer support workflows - Connect external AI agents to customer conversations For endpoint-specific parameters, request bodies, response schemas, pagination, errors, and examples, browse the API reference pages under https://developers.chatway.app/operations/ ## API Resources ### Widgets Use the Widgets API to retrieve chat widgets associated with a Chatway workspace. ### Contacts Use the Contacts API to retrieve, initialize, and update visitor and customer information. ### Conversations Use the Conversations API to retrieve customer conversations, access conversation information, read messages, and resolve conversations. ### Messages Use the Messages API to send new messages into Chatway conversations. This can be used by external systems and AI agents to respond to customers through Chatway. ### Agents Use the Agents API to list agents, retrieve agent details, and invite agents. ## Webhooks Chatway Webhooks provide event-driven, near real-time notifications when activity occurs inside Chatway. Webhook documentation: https://developers.chatway.app/webhooks/guides.webhooks_overview Webhooks can be used to react to events including: - New visitor messages - New conversations - Conversation updates - Conversation resolution - Contact updates - Agent assignments - Tag assignments and removals - Custom data changes - Other supported Chatway events Chatway sends webhook events as HTTP POST requests to a configured HTTPS endpoint. Webhook requests should be authenticated by verifying the `X-Chatway-Signature` and `X-Chatway-Timestamp` headers. Webhook consumers should respond quickly with a successful 2xx HTTP status and process heavier workloads asynchronously. Webhook deliveries use at-least-once delivery semantics, so integrations should handle duplicate events idempotently. Full webhook behavior, event payloads, signature verification, retries, security requirements, and examples are documented here: https://developers.chatway.app/webhooks/guides.webhooks_overview ## API and Webhooks for AI Agents Chatway can be connected to external AI agents and large language models using the REST API and Webhooks. Supported use cases include agents powered by ChatGPT, OpenAI models, Claude, Gemini, Codex, custom LLM applications, and other AI frameworks. A common AI agent workflow is: 1. Subscribe to Chatway's `message.received` webhook. 2. Receive the visitor message and conversation information. 3. Pass the message and relevant context to an external AI agent. 4. Generate a response using the external AI system. 5. Send the response back to the Chatway conversation using the REST API. 6. Continue listening for additional customer messages through Webhooks. This allows external AI systems to operate directly with Chatway conversations while Chatway manages the customer communication interface, conversation history, contacts, and messaging infrastructure. More information: https://chatway.app/bring-your-own-ai ## Authentication All Chatway REST API requests require an API key. Include the key using: `X-API-KEY: YOUR_API_KEY` API keys should only be used in secure server-side environments. Do not expose API keys in browser-side JavaScript, public repositories, frontend applications, or public documentation. ## Response Format Chatway REST API responses use JSON. List endpoints support pagination. API errors use standard HTTP status codes and JSON error responses. Refer to the official documentation for the latest pagination rules, rate limits, request schemas, response schemas, and error handling behavior: https://developers.chatway.app/ ## Real-Time Integrations When an application needs to react immediately to Chatway activity, use Webhooks instead of repeatedly polling API endpoints. For example, to automatically respond when a visitor sends a message: 1. Subscribe to the `message.received` webhook. 2. Read the conversation ID from the webhook payload. 3. Process the visitor message. 4. Send a response through the Chatway Messages API. ## JavaScript Functions Chatway also provides JavaScript functions for controlling the Chatway widget from a website. They can be used to: - Open or close the Chatway widget - Show or hide the widget - Update visitor information - Add tags - Add custom data - Retrieve widget state - Integrate Chatway with logged-in user experiences Developer guides: https://chatway.app/help/for-developers ## Visitor Verification Visitor Verification allows websites with authenticated users to securely associate logged-in visitors with their Chatway identity and ensure users only see conversations belonging to them. Visitor Verification works independently of the application's programming language or framework.
