The following request body posted to the Account entity set will create a total of four new entities in the context of creating an account.
· A contact is created because it is defined as an object property of the single-valued navigation property primarycontactid.
· An opportunity is created because it is defined as an object within an array that is set to the value of a collection-valued navigation property opportunity_customer_accounts.
· A task is created because it is defined an object within an array that is set to the value of a collection-valued navigation property Opportunity_Tasks.The following is the source I used for this:

}

let error = JSON.parse(this.response).error;
alert(error.message);

req.send(JSON.stringify(
