Client secret

What is a client secret? Why use one?

Every app has a unique client secret. This is a sensitive value that's shared between Canva and your app. You need this secret to verify request signatures.

To get your app's client secret:

  1. Navigate to an app via the Developer Portal.
  2. Open the Verification page.
  3. Under the Client secret field, click Copy.

We recommend storing client secrets as environment variables.
