  • SEO Feature Deprecation: On Tuesday, March 31, 2026, Marketo Engage will deprecate the Search Engine Optimization feature (SEO). If you don’t actively use SEO, you don’t have to do anything. If you have used SEO recently, you have the option of exporting your data. Learn more.

  • REST API Merge Leads limit: Beginning March 31, 2026, calls that include more than 25 IDs in the leadIds parameter of a Merge Leads API call will result in a 1080 error code, and the call will be skipped. Jobs requiring the merger of more than 25 records into one should be split into multiple jobs to ensure the success of those calls.

  • Rest API ‘access_token’ Parameter Deprecation: The access_token query parameter used to authenticate Marketo REST API calls is being deprecated and will not be available after July 31, 2026. All new and existing integrations should authenticate REST API calls using the ‘Authorization’ header, as described here.

  • SOAP API Deprecation: Support for the Marketo SOAP API will end on July 31, 2026. Services which use SOAP API capabilities should be migrated to the REST API.
