Hi,

New [make.com](http://make.com) user here with limited technical knowhow 😃 I started to get familiar and have built a workflow creating Bexio (accounting software) orders for new Shopify orders. Most works smoothly now (see full scenario at the bottom), but I’m struggling with a part of the workflow to create invoices from an order.

Bexio is a verified app, but the specific endpoint isn’t included as a module, so I’m writing the call myself. I’ve created a simpler scenario to focus on the problematic part - see blueprint attached.

**Issue:**  
Whenever the scenario is run, I’m getting an error [415] Could not parse the data.  
The (in my opinion) exact same request from Postman works however.

Here is my scenario:

My hypothesis is that I’m incorrectly passing the header. When I remove the header (Accept: application/json) in my Postman request, I’m also getting an error 415:

**Question:**  
Am I correction passing the header in [make.com](http://make.com)? Is something else wrong in my request that could explain the difference between [make.com](http://make.com) and Postman?

**Additional infos:**

- For reference, here is the API docs for the endpoint I’m trying to connect to [bexio API documentation](https://docs.bexio.com/#tag/Orders/operation/v2CreateInvoiceFromOrder).
- Authentication: In my Postman request I use a simple API token. In [make.com](http://make.com) I use the default authentication mechanism for the.
- Blueprint: [blueprint.json](https://community.make.com/uploads/short-url/7FpuA96jBHh9dCt77x2Ydjus82X.json) (17.0 KB)
- Full scenario for reference

Any help is greatly appreciated!
