Hi Georgios,

I've had a review of your post and what I'd recommend is to go through our dedicated Sage Developer Help site that I've linked below. Here you can select the specific Sage Product it is you're developing for, which then has setup instructions as well as guidance on testing and the various endpoints available.

Let’s build great things together | Sage Developer

Hopefully the above site guides you in the direction needed,

Kind Regards,
Andrew
