# API End-of-Life Policy

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

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 63.0 | Supported.                                                                                                                                                  |                                                                                                                                               |
| Versions 21.0 through 30.0 | As of Summer ’22, these versions are deprecated and no longer supported by Salesforce. Starting Summer ’25, these versions will be retired and unavailable. | [Salesforce Platform API Versions 21.0 through 30.0 Retirement](https://help.salesforce.com/s/articleView?id=000389618&type=1&language=en_US) |
| 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](https://help.salesforce.com/s/articleView?id=000380623&type=1&language=en_US)  |

If you request any resource or use an operation from a retired API version, REST API returns the 410:GONE error code.

To identify requests made from old or unsupported API versions, use the [API Total Usage](https://developer.salesforce.com/docs/atlas.en-us.254.0.object_reference.meta/object_reference/sforce_api_objects_eventlogfile_apitotalusage.htm) event type.
