Webhook Send API

Send HTTP POST requests to any URL with any JSON payload via REST API. AI agents cannot make outbound HTTP calls natively — this API bridges that gap, allowing agents to trigger Zapier zaps, notify Slack via webhooks, update external systems, or call any REST API.

How it works

POST the target URL, payload, and optional headers. The API makes an HTTP POST request to the target, waits for a response, and returns the HTTP status code, response headers, and response body. Supports custom headers for authentication.

Use cases

• Trigger Zapier or Make.com automations from an AI agent workflow
• Send Slack or Discord notifications when an agent completes a task
• Update a CRM or project management tool at the end of a workflow
• Call any REST API from an agent that cannot make outbound requests directly
