Integration with C4C OData API using CI

Hello Experts,

We have a scenario where we need to do a PATCH request with C4C OData API. This involves 2 steps in CI:

1. Fetch "Object ID" for a specific field Ex: Employee ID

2. Pass this "Object ID" in the URL

Only with the Object ID does the PATCH work successfully.

I know the ways to fetch object and do a patch call after this.

I specifically wanted to know how does this work when we have multiple employees to be updated.

Do we have to depend upon splitter/gather?

Please suggest

Best Regards
