Check custom function code

Checks the custom functions code. The response contains information whether Make validated the custom functions code successfully or whether there was an error.

The code validation might fail because of an syntax error in the function's code or when the code uses a JavaScript feature that Make doesn't support. Check the custom functions limitations in the Make Help center.

Check availability of the custom functions feature with the API call GET /organizations/{organizationId} for the organization to which the team belongs. If the response contains "customFunctions": true pair in the license object then you have access to the custom functions feature.
