Most requests in our API are single part requests where the Content-Type header describes the single type of content in the body of the request (ie. text/json). This request however is a multipart request which allows you to upload your business license at the same time in the same HTTP requst. The Content-Type header of this request must be set to multipart/form-data.

The individual parts of this request must contain a single part with the data holding the JSON for the user, and the businessregistrationlicense part for holding the information of the file. For the data part, the Content-Disposition must be set to form-data; name="data". The business registration license part must have a Content-Disposition of form-data; name="businessregistrationlicense"; filename="yourfilename.jpg" and cannot exceed 75 characters in length.
