Important: We’re deprecating legacy webhooks on September 1, 2025. To avoid service disruptions, please migrate to our new webhook system before this date.

Why we’re making this change

To improve reliability, consistency, and future scalability, we’ve introduced a new webhook system in the Flex dashboard. The new system provides:

  • Improved delivery reliability
  • Consistent event payload structures
  • Enhanced monitoring and debugging tools
  • Support for more event types and filtering options

Migration timeline

DateMilestone
June 30, 2025Legacy webhook deprecation announcement
September 1, 2025Legacy webhook endpoints will be removed from the API

How to migrate

Follow these steps to transfer your existing webhooks to the new system:

1

Access legacy webhooks

Visit the Legacy Webhooks page in the Flex dashboard to view your existing webhooks.

2

Document your current setup

Make note of the endpoint URL and subscribed events for each legacy webhook.

3

Navigate to the new webhooks page

Go to the Webhooks & Events page in the dashboard to begin recreating your webhooks.

4

Recreate each webhook

For each legacy webhook, create a new webhook using the same endpoint URL and event subscriptions.

5

Test and verify

Once your new webhooks are set up, test them to ensure events are being received correctly.

6

Remove legacy webhooks

After confirming your new webhooks are working properly, you must delete your legacy webhooks to avoid receiving duplicate events.

Important: If you don’t delete your legacy webhooks after migrating, your system will receive duplicate events which may cause issues with your integration.

Key differences to be aware of

The new webhook system is highly compatible with the legacy system. The only significant change is:

  • Signature verification: The new system uses a different signature method

There are no changes to event names or payload structures, ensuring a smooth transition.
