Extensibility for third party application programming interfaces

A system, comprising:

• at least one processor;
• and
• a computer readable storage medium including instructions stored thereon which, when executed by the processor, cause the system to:
• receive a request to perform at least one action on at least one object type, the at least one action defined by an application programming interface (API);
• determine at least one extension associated with the at least one action and at least one object type;
• obtain an object of the at least one object type;
• perform the at least one action to generate an intermediate object;
• send the intermediate object to the at least one extension for processing, the at least one extension hosted by a remote service;
• receive a response from the at least one extension;
• and
• update the intermediate object based on the response.
