Webhooks
Webhooks are a way for your application to receive real-time notifications from external services when specific events occur. Instead of polling for updates, your app can react instantly to changes, making it a powerful tool for data synchronization and automation.
Setting Up Webhooks
To set up webhooks in your Rapture app, follow these steps:
Choose an Event: Decide on the event for which you want to receive notifications. This could be user registration, payment confirmation, or any other event supported by the external service.
Create a Webhook: Log in to the external service's dashboard and create a new webhook. Provide the webhook URL where the service will send notifications.
Implement the Webhook Endpoint: In your Rapture app, create an endpoint to handle incoming webhook requests. This endpoint should validate the incoming data and trigger appropriate actions.
Securing Webhooks
Security is crucial when handling webhooks to prevent unauthorized access or malicious requests. Here's how you can secure your webhook endpoint:
Use Authentication: If the external service supports authentication, require a secret token in the webhook payload. Verify this token in your endpoint to ensure the request is legitimate.
Validate Payload: Check the signature or checksum provided by the external service in the payload to confirm the data's integrity.
Rate Limiting: Implement rate limiting to prevent abuse or excessive requests to your webhook endpoint.
Testing and Debugging
Testing your webhook integration is essential to ensure everything works as expected. Use the external service's dashboard to send test webhook requests and analyze the responses. Additionally, log webhook events and responses to aid debugging.
Best Practices
Document the supported webhook events and payloads in your app's documentation.
Monitor webhook logs to identify errors or issues promptly.
Plan for retries: If your endpoint doesn't respond, some services might retry sending the webhook.
