(REST API) Cannot create new customers from java project but can do it from postman request

[Raul Reyes Monroy]

I'm making a custom front-end to receive customer tickets for Service Desk (Cloud).

I use a Spring Boot project as a middleware to handle security using basic authentication.

I do my tests for Service Desk in postman before getting them to code.

Using this script in postman (https://myProjectSubdomain.atlassian.net/rest/servicedeskapi/request)

{
    "serviceDeskId": "18", 
    "requestTypeId":"289", 
    "requestFieldValues": {
        [...] a lot of custom fields, all correct, 
        "summary":"Request summary"
    }, 
    "raiseOnBehalfOf":"newCustomerMail@mail.com"
}

It works perfectly, the call returns the newly created request.

But when generating the same request in my java project (Spring boot, using Unirest to handle the REST calls) it returns a  HTTP 400 error with error message:

Your request could not be created. Please check the fields have been correctly filled in. Cannot add new customers.

I printed Unirest generated request and it is exactly the same as the one I put in postman.

Furthermore when I remove the part that adds the 'raiseOnBehalfOf' from my java code the request is correctly generated.

Why is it that I can create new users from postman and I can't do it from my java project?

What permissions does your java project have?

This is copied directly from the docs

The fields required for a customer request type depend on the user's permissions:

• raiseOnBehalfOf is not available to Users who have the customer permission only.
