Adobe has officially announced two major deprecations coming October 31, 2025.
🔒REST API access_token Parameter Deprecation
The use of access_token in query parameters for authentication is being phased out. Moving forward, all API calls must use the authorization header.
🧼 SOAP API Deprecation
Support for the Marketo SOAP API is ending now. If you're relying on SOAP based integrations, now is the time to start migrating to REST API.
These changes impact integrations, lead routing, custom workflows and reporting.
