I've created an HTML field on our accounts record to be filled with custom HTML from our financial system. The HTML of the field should be stored on a per account basis, but only updated via a REST "PUT" call coming from our financial system. I've validated that all other fields are able to be updated via REST, but these ones just won't stick.
REST calls seem unable to update HTML fields for specific records, which makes me think I'm taking the wrong approach.
Any help would be appreciated.
