[Aside: I have tweeted about this and sent an email before realising this is the best home for this question, so my apologies for cross posting.]
We are currently in the process of writing a Drupal module for integrating with Marketo's REST API. This will be released to the Drupal community as an open source project. We would like to be able to bundle automated API testing within this module that tests basic API request / response interactions. Obviously then, a company specific Marketo Sandox is not the right place to test this.
Is it possible that Marketo has or can provide a REST API stub with it's own associated authentication details that allows for request / response testing of the basic API endpoints? Or do you have a suggested alternative for this?
Looking forward to discussing with you further.
I will likely create a mock for the REST API request / response, but it would be nice to have this real world example sandbox available for community projects. Thanks.
