Simple Twinfield API request with Postman

Question

I want to connect sales invoices with javascript/ google apps script. Therefore I want to test some things with Postman. I know, that the API works with XML and to get data you need to use the so called Browse code 100. But I am stucked with creating a working request to get sales invoice data :(

What I did so far:

• Read the Twinfield API documentation
• Created a login in the developer portal
• Managed to request authorization code with Postman: I did a workaround to adjust the parameters in Postman and then paste the request URL into the browser
• Managed to request access token
• Determine cluster

I did a lot of research but couldn't find any examples I could understand. Examples like

• how should a request URL in Postman look like
• what parameters do I need
• is it possible to have a handy request in javascript to get open sales invoices

I would be very grateful for any help!
