Webhooks are a way for meCash to send your application automatic notifications whenever specific events take place. Instead of your application constantly asking meCash for updates, meCash pushes information to you in real-time. ```mermaid theme={null} sequenceDiagram participant A as meCash System participant B as Your Webhook Endpoint A->>A: Event occurs (payout, collection, etc.) A->>B: Send secure HTTP POST with event payload B-->>A: Return 2XX acknowledgment B->>B: Validate X-Signature using HMAC-512 B->>B: Confirm authenticity of the request ``` The process is straightforward: 1. **An Event Occurs**: Something happens in your account, like a successful payout or a collection. 2. **meCash Sends a Request**: We send a secure HTTP POST request containing the event details to the webhook URL you've configured. 3. **You Acknowledge and Verify**: Your server acknowledges receipt by returning a `2XX` status code and then validates the request's signature to confirm it's genuinely from meCash. All meCash webhook events are signed using an `HMAC-512` signature in the `X-Signature` header. The signature is computed from the raw request body using your webhook secret key (found in **Developers → Webhooks** in your dashboard). Always verify this signature before processing the event to ensure authenticity and prevent replay attacks. * Reject requests with missing or invalid signatures. * Log every webhook delivery for auditability. * Retry failed processing gracefully and return `2XX` only after you persist the event. In the **Developers** section of your meCash dashboard, select **Webhooks** from the left-hand menu to review existing endpoints and create new ones. Developers dashboard highlighting the Webhooks navigation item Click the **Create Webhook** button at the top-right corner to launch the configuration modal for a new endpoint. Create webhook dialog in the meCash dashboard * Enter the publicly accessible **URL** where you want to receive webhook events.
* Ensure the endpoint accepts HTTPS POST requests and responds within 10 seconds.
* Return an HTTP **2XX status code** to acknowledge receipt and prevent retries. Webhook configuration form requesting callback URL After clicking **Confirm**, your webhook appears in the list with its current status. Use the dashboard to pause, resume, or regenerate the signing secret if needed.
