Subscription Payment Update Webhook Not Triggering in Sandbox

JohnyEnglish — Mon, 24 Nov 2025 13:51:18 GMT

Hi Team,

I’m testing Cybersource Subscription Payments in the Sandbox environment, and I’m facing an issue where the subscription payment update webhook is not triggering.

Here is my current setup:
Subscription status: Active
Webhook status: Active
Payment status: Paid (using a Cybersource test card)
Health check URL is working correctly
POST request to my webhook endpoint works when tested manually through Postman

But Cybersource is not sending any subscription payment update webhook events to my callback URL.
I’m not sure if I’m missing any configuration or if there is a Sandbox limitation with subscription webhook events.

Could someone please guide me on what else to check or confirm if this is a known Sandbox issue?
Thank you

I’d double-check the event types enabled for your webhook in the Sandbox. Sometimes the payment update events aren’t selected by default, even if the webhook shows as active.
