Security and Verification#

Critical Security Notice
Before processing any webhook notification, always verify its authenticity. This is required for a secure and reliable integration.

Authentication Token Verification#

Every webhook request includes a shared secret token in the HTTP headers.
Implementation steps:
1.
Extract the token
2.
Verify it against your secret
3.
Reject invalid requests
Reject requests with missing or invalid tokens.
If needed, add extra replay protection such as timestamp or nonce validation in your own middleware.

Getting Your Secret Token#

Your webhook secret is provided together with your API credentials during integration setup. Store it securely and never expose it in client-side code.

Delivery and Retry Policy#

Acknowledging Receipt#

Return any 2xx HTTP status code to confirm successful processing.

Automatic Retry Mechanism#

If delivery fails, up to 4 additional attempts are made with increasing delays.
AttemptDelay After Previous FailureStatus
1st-Initial delivery
2nd~8 secondsFirst retry
3rd~16 secondsSecond retry
4th~32 secondsThird retry
5th~64 secondsFinal retry

Retry Behavior#

Failure Condition: Non-2xx responses or timeouts trigger retries.
Exponential Backoff: Delay increases between attempts.
Timeout: Each request times out after 10 seconds.
Final State: After 5 failed attempts in total, the webhook is treated as permanently failed.
