Webhook Implementation Best Practices

What are some of the best practices in implementing webhooks?

To ensure your system handles webhook events efficiently and securely, here are some key practices we recommend:

  1. Acknowledge Webhooks Quickly
    Always respond with an HTTP 2xx status code as soon as you receive the event. This confirms to PayMongo that your system has accepted the webhook, even if further processing happens asynchronously.
  2. Log and Monitor Events
    Log all received webhook events for debugging and traceability. Set up alerts to monitor for failures or unexpected status codes so your team can respond promptly to issues.
  3. Reconcile Missed Events
    If your webhook URL becomes temporarily unavailable, you can use the PayMongo API as a rollback mechanism by retrieving the Payment Intent to determine the status of the transaction.
  4. (Optional) Secure Your Webhook
    To protect your endpoints from unauthorized requests, verify the Paymongo-Signature header in each request. This helps confirm that the webhook is genuinely from PayMongo. Refer to our Securing a Webhook section for full implementation details.
