New Webhook APIs to Test and Manage Subscriptions Now Available

[rajvpate]

Webhook integrations are critical for delivering real-time event updates to your systems. To make this process more seamless, we’re excited to introduce two new webhook APIs that simplify testing and subscription management.

These APIs are now available in both our Developer Center and Production environments — designed to accelerate your development and give you more control over event delivery.

What’s New

1. Test Webhook Delivery Instantly

Simulate webhook event delivery with a simple POST request — no need to wait for a live transaction.

Endpoint:

POST /notification-subscriptions/v1/webhooks/{webhookId}

Use Cases:

• Validate that your webhook receiver is set up correctly

• Troubleshoot and test retry behavior

• Accelerate QA during integration

---

2. Activate or Deactivate Webhook Subscriptions

Update the status of a webhook subscription without recreating it.

Endpoint:

PUT /notification-subscriptions/v2/webhooks/{webhookId}

Payloads:
To activate:

{  "status": "ACTIVE" }

To deactivate:

{  "status": "INACTIVE" }

Use Cases:

• Temporarily pause delivery during maintenance

• Re-enable subscriptions easily

• Streamline partner and environment management

Versioning Clarification

We want to be fully transparent about API versioning for our Webhooks platform:

API Functionality	Version	Endpoint Format
Test Webhook Delivery	v1	POST /notification-subscriptions/v1/webhooks/{webhookId}
Activate/Deactivate Subscription	v2	PUT /notification-subscriptions/v2/webhooks/{webhookId}
All other webhook subscription APIs	v2	Create, Update, Delete webhooks)

Why This Matters

These new APIs give you the tools to validate, manage, and control webhook behavior without friction. Whether you're testing in sandbox or going live, you'll save time and reduce integration risk.
