API End-of-Life Policy

Salesforce is committed to supporting each API version for a minimum of 3 years from the date of first release. To mature and improve the quality and performance of the API, versions that are over 3 years old sometimes are no longer supported.

Salesforce notifies customers who use an API version scheduled for deprecation at least 1 year before support for the version ends.

Versions 21.0 through 30.0 of UI API will be deprecated in the Summer ’22 release. For more information, see this Knowledge Article: Salesforce Platform API Versions 21.0 through 30.0 Retirement.
