There are two ways to request authentication to use the Shipium ShipTime API:

Each has its advantages and disadvantages and each also has its adherents, so we support both mechanisms.

Flow differences

The primary difference in flow between the two mechanisms is how you use them to make subsequent calls to the API:

Type of authentication

Calling method

API key authentication using Basic Authentication

You authorize as part of making each call by passing your API Key information in the Authorization field.

OAuth 2.0 using the Authorization request header or authorization URL parameter

You authorize and then receive a token and an expiry time.
You use that token for your calls to the other APIs.
