Attached is an example Postman project with a sequence for document upload in parts (bestandsdelen).

Please pay attention to the following:

• the JWT should be generated using a Client ID and secret
• the field bronorganisatie in the body of step 1 should contain the rsin of the organisation that owns the DRC (thus, the rsin of the customer)
• the field “inhoud” in the body of step 1 should be null
• the field “bestandsomvang” in the body of step 1 should match the number if bytes in your sample file in step 2
• the response to step 1 contains a lock, and the url to the bestandsdelen
