I am trying to insert record into Member Plan object using composite API. Note : For simplicity in the below request I removed all other post in coposite API and adding only one with hard coded values

string bodyVal='{ "compositeRequest": [  { "method": "POST", "url": "/services/data/v45.0/sobjects/MemberPlan", "referenceId": "refMemberPlan", "body": {"MemberId": "0018b00002Q5fL0AAJ", "PayerId": "0018b00002LHZUYAA5", "MemberNumber": "36478019000",  "Name" : "LIBERTY NETWORK" } }] }';

                req.setHeader('Authorization','Bearer '+getAccessToken.Access_Token__c);
                req.setHeader('Content-Type', 'application/json'); 
                req.setEndpoint(envDetails.Base_URL__c+ '/services/data/v55.0/composite/'); 
                Http h = new Http(); 
                HttpResponse res = h.send(req); 

but getting this error

{"compositeResponse":[{"body":[{"message":"entity type cannot be inserted: Member Plan","errorCode":"CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY","fields":[]}],"httpHeaders":{},"httpStatusCode":400,"referenceId":"refMemberPlan"}]}

I tried by inserting into direct object as like below

MemberPlan plan= new MemberPlan();
insert plan;

and it is going through.

I havent didn't do any code change and suddenly getting this issue in PROD but things are working fine in sand box

    Try keeping you API version in sync. Anyways that shouldn't affect this call. I dont see any issue on your code. Check the user permission. The integration user who is making the composite api call. Commented Apr 17, 2023 at 6:06
  • @NagendraSingh .As like you said its permission issue

When using rest api to insert object. The running user needs to have access to do that operation.

It works in apex because apex runs in System mode.

Please check the permissions assigned to user with which the API call is being made.
