    Webhooks (Reference)

    Reference examples for webhook payloads sent by the system. These are not API endpoints - they are sent to your configured postbackUrl.
    HMAC Signature Verification:
    If webhookSecret was provided during transaction creation, the X-Webhook-Signature header will contain the HMAC-SHA256 signature of the request body.
    Verification Steps:
    1.
    Get the raw request body (as string)
    2.
    Compute HMAC-SHA256 using your webhookSecret
    3.
    Compare with the X-Webhook-Signature header value
    4.
    Only process the webhook if signatures match
