# External Services

External services support enums. There are a number of enhancements in this release.

- **[Build More Robust Integrations with External Services Support for Enums](https://help.salesforce.com/s/articleView?id=release-notes.rn_ext_services_schema_enums.htm&release=262.0.0&type=5)**  
    You can now include enums in the OpenAPI specification that you use to create an external service. When you add the external service to a Flow action element, the enum appears as a picklist. In other Flow elements and in Apex, the enum appears as its base type. You can use either string or number as the enum value type. Support for enums is only available in external service registrations created after the Summer ’26 release.
- **[Do More with External Services Binary File Improvements](https://help.salesforce.com/s/articleView?id=release-notes.rn_ext_services_enhancements.htm&release=262.0.0&type=5)**  
    External Services now provides a 100-MB file size limit for binary file operations, optional custom filename input in Flow Builder, and smarter file name resolution with a defined priority order.
