Qlik Stitch: Marketo Integration and the access_token change in 2026

David_Apodaca — Thu, 06 Nov 2025 08:24:31 GMT

The goal of this article is to address the upcoming changes announced by Marketo regarding the deprecation of authentication via the access_token query parameter, which will no longer be supported after January 31, 2026. For further details, please refer to: Using an Access Token | Marketo Developer Guide.

Marketo specificities: "If your project uses a query parameter to pass the access token, it should be updated to use the Authorization header as soon as possible. New development should use the Authorization header exclusively".

The Stitch Marketo integration (V2) already handles authentication using access tokens, as outlined in Marketo’s documentation. Specifically, Stitch includes a Bearer token in the Authorization header of its API calls. This approach complies with Marketo’s authentication requirements, so no additional configuration is needed on your end.

For reference, please visit the integration's repository | github.com.
