Change the Salesforce API version on Heroku Connect

Change effective on 31 July 2026

You can now change the Salesforce API version on your Heroku Connect connections. Previously, changing the API version on an existing connection required a support ticket. Use the Heroku Connect dashboard or the Heroku Connect CLI to select your target API version, compare schemas, and change API versions.

See Managing Heroku Connect Sync and Connections for more information.
