You can now pin a new contact note via the API. Also, we added the ability to enter a “new line” character in the note. Please see the updated documentation for details. AddContactNote
You will have this in the next update, once your installed version is 4/26/2017 or later.
Good news! We’ve gone back and updated all older API functions to include the option to return the result data as JSON or XML data. XML was the only option for the API functions created in the past.
If you still want XML results, you don’t need to do anything. All results default to XML. If you want your results in JSON, add the field “response_type” to your request fields and set the value to “json”.
You can choose whichever format is easiest to consume in your favorite programming language.
