• Effective members: An effective member is either a direct member of the group or an effective member of a member group

Use of POST method

The Groups API accepts the POST method for two purposes:

URI too long
If your uri would be too long for likely transport to the web service you may enclose it in a POST, with the elements:

<span class="_method"> GET | PUT | DELETE </span>
<span class="_uri"> uri </span>

included in the POST document.  The path components of you actual URL must match those in the posted "_uri".

PUT content too big
If your PUT content would be too big for likely transport to the web service you may enclose it in a POST, with the element:

<span class="_method">PUT</span>

...

Large membership changes

If you are making large membership changes, say more than a few hundred, your experience will be better if you split your activity into adds or deletes of fifty to a hundred members at a time.  This tends to give you immediate feedback on successful changes and avoids possible session or connection timeouts.
