MyBring API Key:
The customer needs a MyBring account, use it to generate an API key, and get authorized with the "buyer role". This is described here:
MyBring API Customer Number:
Log in to https://www.mybring.com, click "your profile" then click the "API customer number" tab.
One MyBring account can have multiple API customer numbers, for example one for Bring Parcel, one for Bring Express. In that case, create one Shipping Method for each customer number.
Select a service that the "MyBring API Customer Number" is valid for. For example, a Bring Parcel customer number is valid for "Klimanøytral Servicepakke" but not "Bud 1 time".
