Hi,
The MYOB Business API documentation is a bit vague as they offer a large suite of products.
I wanted to put this on the forum incase anyone else is setting up the API.
You will find the instructions to create an application and generate some API credentials at:
You then want to log into your developer dashboard at: https://my.myob.com.au/Bd/Pages/home.aspx
You can view your API credentials under the “developer” tab in your dashboard
You then want to set up authorization at this link: https://secure.myob.com/oauth2/v1/authorize and the documentation for this is at: Authentication
