I see many posts related to trouble accessing custom fields via API. I don’t want to pay to add custom fields just to later discover that they are not accessible via API.
I don’t see confirmation of resolutions listed…
Are Custom Fields on the Job Record accessible via API?
Are there any current issues, other than user originated, that may prevent access to a custom field on the Job record?
Yes, once a Job custom field exists on an account, its value is accessible through the Job record in the REST API. The API field name uses the customfield_ prefix.
Creating or managing custom-field definitions through the Custom Fields API is limited to Public Applications using OAuth 2.0. Existing custom-field values can be read or written through the REST API.
