SOAP API End-of-Life Policy

See which SOAP API versions are supported, unsupported, or unavailable.

The SOAP API login() call is scheduled for retirement in Summer ‘27. The login() call will be supported in API versions 62.0, 63.0, and 64.0 for a minimum of two years following the release of the version.

Note

Salesforce is committed to supporting each API version for a minimum of 3 years from the date of first release. To 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.

Salesforce API Versions Version Support Status Version Retirement Info
Versions 31.0 through 64.0 Supported.
Versions 21.0 through 30.0 As of Summer ’25, these versions are retired and unavailable. Salesforce Platform API Versions 21.0 through 30.0 Retirement
Versions 7.0 through 20.0 As of Summer ’22, these versions are retired and unavailable. Salesforce Platform API Versions 7.0 through 20.0 Retirement

If you request any resource or use an operation from a retired API version, SOAP API returns 500:UNSUPPORTED_API_VERSION error code.

To identify requests made from old or unsupported API versions, use the API Total Usage event type.
