Documentation
Connect an authorized WhatsApp number to your application. Start with a scoped key, then follow the request through the queue and signed delivery events.
Start an integration
Verify your account, connect your number from WhatsApp Linked devices, and create an API key. The trial supports individual text messages to your linked number or support-approved recipients. Group and advanced operations require a paid plan.
Build against the contract
Use the OpenAPI specification for request schemas, methods and permissions. Sending endpoints return HTTP 202 when a request enters the queue. Read and delivery receipts depend on WhatsApp and the recipient’s settings.
Integration guides
Quickstart
Verify your account, connect a number, create a scoped key, and queue your first text message.
Authentication
Use expiring Bearer tokens with read, send, and manage permissions. Session scoping limits access further.
WhatsApp sessions
Create a session, authorize it through Linked devices, inspect connection state, and manage its lifecycle.
Text messages
Queue a text message using a connected session and a per-message idempotency key.
Images and PDFs
Send JPEG/PNG images and PDF documents as bounded base64 payloads on a paid plan.
Contacts, chats, and groups
Read data available through a connected WhatsApp account using a session-scoped read key.
Delivery and retries
Understand queue acceptance, delivery receipts, and how to handle sends whose outcome is uncertain.
Webhooks
Configure HTTPS destinations, verify raw-body signatures, and deduplicate repeated deliveries.
Limits and billing
Trial restrictions, per-plan sending allowances, time windows, and cancellation behavior.
Errors and troubleshooting
Interpret error codes and choose the appropriate correction rather than repeating requests blindly.
Security and service model
Credential handling, account isolation, data retention, and the limitations of independent WhatsApp connectivity.
API reference
The supported public endpoints, required scopes, response envelope, and format conventions.
Groups
Create groups, manage participants, share invite links, and send messages to a group you are authorized to use.
Capabilities and limits

Agents and discovery
