[Ginger Payments] Why does a «GET merchants/self/projects/self/» request lead to the «You don't have the permission to access the requested resource» response?

As Ginger Payments and Kassa Compleet lask the real API documentation, I have used the following code from the official Kassa Compleet extension for Magento 1.x as an example:

It is for Kassa Compleet, but Kassa Compleet’s does not document the merchants/ API part at all, while Ginger Payments’s documentation does, so I made a request to the Ginger Payments API, but got a response:

	"error": {
		"type": "<class 'werkzeug.exceptions.Forbidden'>",
		"value": "You don't have the permission to access the requested resource. It is either read-protected or not readable by the server."

Hello, @Joachim_de_Boer, why is it?

Interestingly, the same request works for Kassa Compleet, despite the «merchants/» API part is totally undocumented for Kassa Compleet.

When I specify exact merchant_id and project_id instead of the «self» value, this API part does not work too.

I have got an answer:

On Ginger this feature is not enabled yet, will be enabled soon.
