Add in ChatGPT

Three steps in ChatGPT.

Add the connection, sign in at Fortnox and ask a question. ChatGPT asks before it fetches data.

01
Create a GPT in ChatGPT
In ChatGPT: create a GPT, or open one you already have. Add an Action and paste Addresses to paste in ChatGPT.
02
Connect Fortnox
When ChatGPT needs company data, choose Connect. Sign in at Fortnox and pick a company.
03
Ask a question
Try for example: Which customer invoices are due this week? Approve when ChatGPT asks to fetch data.
