ServiceDesk OnDemand Request API only accepts up to 75 characters in description

ServiceDesk OnDemand Request API only accepts up to 75 characters in description

I am calling the ADD_REQUEST api endpoint with INPUT_DATA as follows, replacing subject and description with actual data:

{operation:{Details:{REQUESTER:Technical, SUBJECT: subject, PRIORITY:Medium, DESCRIPTION: description }}}

If I send this with subject and description being 75 characters or less the request saves.
If I send this with a subject or description being more than 75 characters I get "Bad Request(400)" as the response.

I have checked this with strings that are just a series of the letter "A" to be sure that the problem is not in the string content.

I know the description takes more than 75 characters. Is the API limited to 75 characters for field data? Is this limit applied to all fields via the API?

Has anyone else come accross this limitation? Is there a way round it?
