[Signature Verification](https://www.canva.dev/docs/extensions/backend-development/verify-request/) support for the Canva Apps SDK will be removed on May 12th, 2024.If your app does not use Signature Verification then no further action is required.

- If your app is still using the legacy Signature Verification then you will need to remove this from your app’s backend before May 12th to avoid disruption to your users.
- The change should not require a new app submission.
- We will run two “brownout” periods where you can verify the change. We will temporarily turn off Signature Verification support from April 29th - 30th and then again from May 6th-8th. Both periods will start and finish and 10am AEST

Hi @Torey

What is this getting replaced with? For Canva Extensions, this is the only way we validate the requests. Is there any new way to validate the requests?

Hi @coral ,

For Canva Extensions this is not being deprecated. This is only being deprecated for Canva SDK apps, which use JWTs instead, you can read more about verifying JWTs [in the developer documentation](https://www.canva.dev/docs/apps/verifying-jwts/)
