That's possible (we've done it here), but then you have to retrieve the group membership from Grouper plus the intended membership from your external source. Then, do a two-way compare to generate changes and call the API to make those changes.

Now imagine you want to do that for, say, all course groups for a specific term... That's a lot of extra work! :)

Grouper newbie here. I would likely need something similar. Why not write
intermediary code to use Grouper web services? That was my plan, so I'm
curious as to what I'm missing.

Subject: [grouper-users] Grouper Loader - of another type

Hi all,

Currently, grouper supports loader jobs of LDAP and SQL and an additional
capability to inject messages to process changes related to an individual - a
way of sparking loader jobs for one person instead of in bulk - at least this
is my interpretation.

I have a need for loader jobs to be of an arbitrary nature - call a program,
written in any language, which might do REST calls or whatever and return, in
bulk, something similar to what the loader job now receives from SQL/LDAP.
This way I can go against alternative sources without the need of staging the
data into LDAP/SQL but get all the benefits and scale of a grouper loader job.

Does anyone else see a need for this? Grouper dev dudes… (and dudettes)…
have you considered this? I can only assume you have since you guys have
thought of a great many things for grouper.

Many thanks for your time and consideration especially if you choose to
