The CO3 API is a mostly RESTful API. Known caveats:
Request data is passed to the API by POSTing XML objects to the API endpoints with the appropriate structure. The documentation for each API call will contain more details on the parameters accepted by the call.
API supports XML output format only.
If CO3 is having trouble, you might get an error code with an error description. It’s your responsibility in all of these cases to correct and retry your request later.
You can perform 2 requests per 1 second period from the same IP address for the same account. If you exceed this limit, you’ll get a Too Many Requests response.
Currently API supports the following CO3 plugins:
