Pretty Useless Error Message When Testing
Trying to TEST my digest and I get a useless "Marketo Error" message (see attached).
How does that help me troubleshoot anything?

Error message are all updated, providing specific errors based on the original issue. Ex: Invalid Program Name, API Limit Reached, etc. See all details on Marketo error messages here http://developers.marketo.com/rest-api/error-codes/#response_level_errors. **Requires REST API Web Service.
