Updating APIs in Flow

With the Salesforce changes in Spring and Summer of '25, the API versions for Apex Classes, Apex Triggers, and Visualforce pages need to be updated to 45 and above.

If you have custom work in your org(s), you should update your Flows to the newer versions of the APIs. It’s important to upgrade your Flow API versions periodically. This update is not mandatory now, but it may become required in the future.

Reminder: You should review/upgrade Custom Flows periodically.

Upgrading your Flows

Note: Complete these steps in a sandbox environment and test them before updating production. When your sandbox updates to the latest release, it will have higher API versions than production. A Change Set cannot be created from the sandbox to production if the API versions do not match.

  1. Navigate to Setup and search for Flows.
  2. Click the Flow to update.
  3. Click the View Properties gear icon:

  2. Move the Flow to production.
