I still didn't manage to obtain an API Key for Sage accounting. I made some API calls through Postman with OAuth using the access token. I want to retrieve data, like invoices and credit notes, from Sage Accounting and insert them into an excel worksheet in order to be able to use the in calculations. In order to do that excel asks me for authorization. So I need an API Key in order to proceed with the API call in excel.
I use Sage Business on cloud.
Any help will be useful.
Thank you in advance.
