You're hitting this issue since the member service does not take an array(https://developers.jivesoftware.com/api/v3/cloud/rest/MemberService.html#createMember(String, String, String, String)). You can only pass those two fields in an object. What you will need to do in order to save requests is to run a batch:
I believe you're limited to 25 operations per http request. Hope this helps!
Hello Rashed Talukder,
Thank you for the response. As I am a beginner when it comes to API and JSON, would you be able to provide an example for such a batch request.
What would the URL and the payload look like as i see a "POST /executeBatch" in the documentation you sent and i am not sure how to process this.
Thank you in advance,
