API calls to real account instead of SOD tenant

Hi,

I have developed an API integration with SuperOffice using a developer account (tenant Cust55171) at the endpoint https://sod3.superoffice.com/Cust55171/api/. Everything works correctly against this developer tenant.

Now, I want to connect the same API to the production tenant (Cust15673) at https://online4.superoffice.com/Cust15673/api/ so that I can access the real data.

My question is:

How do I register my integration/app against the production tenant?

Thank you in advance.
