问题
We have an internal database ID for each course we have. When using the batch function to create courses, the returned information doesn’t not give us any way to get this ID back so we cannot update our database and let it know that the course has been created.
Also updating the deletion response for the same reason would also be handy.
The response for a batch of deletes looks like:
--batch_123456
{}
--batch_123456
--batch_123456
{}
--batch_123456
--batch_123456
{}
--batch_123456
If they are all successful then it's not really a problem, but if something goes wrong then it's impossible to tell which ones were deleted and which ones were not deleted, because according to the API:
" The server may perform your calls in any order. Don't count on their being executed in the order in which you specified them."
A simple message that said "course #123 has been deleted" would be very helpful. That way I could program the callback code to update the database using the ID
For the course creation the response looks like:
--batch_123456
{
"id": "208571459",
"name": "***",
"section": "***",
"ownerId": "123456",
"creationTime": "2015-09-14T13:13:59.622Z",
"updateTime": "2015-09-14T13:14:02.820Z",
"enrollmentCode": "***",
"courseState": "PROVISIONED",
"alternateLink": "***"
}
--batch_123456
I only put in one response to save space. The ID is the new GoogleID of the course, the ID we actually send in which corresponds to the records in our DB does not get returned. So we have to use a combination of other data (ownerID + name) to get the record and update it, but this is not ideal and may not work fro everyone. Again adding in all of the information that get's sent into the response would be very helpful so we can use the callback properly.
I also want to add the more useful specific information should also be added to all error messages. In fact every batch response should have some sort of ID, that way the callback functions can be more useful.

As mentioned briefly in the documentation, you can pass an alias into Courses.id when creating a course to assign an alias to a course as you create it. The alias can include your internal identifier for the course and can be used in future requests.
Alternatively, each request in a batch can be assigned a unique Content-ID header, which will be returned in the response. Many client libraries provide built-in support for setting and getting these IDs.
