Help for Aimeos

Every minute is fine and you should use the name of the delivery option the customer should see as label/name of the entry. You can also have several delivery options with different names and codes but the same provider value.

Ok, thanks a lot. I have another question, to be able to use QuickBook API, I need to connect my website to the account on QuickBook, where and how I can create a page on admil panel to place my "Connect" button? I need controller to generate connect URL and pass it to view and then when user connected I need to save tokens in DB. What is the most appropriate way to do this?

You mean an OAuth handshake? You can overwrite the template for the service detail panel and add the button there:

Yes, I mean OAuth authorization. How I can add a backend code? I need to generate Authorization URL using QuickBook SDK and pass it to the template for the service detail panel. After the user goes through the authorization flow I get a response from quickbook with tokens which I need to process and save to db.

The best way might be to create a subpart for the service panel where you can do all stuff you need:
