Authentication to the Liftoff OData API is handled by providing the following with every API request:

Your account code as your Basic Auth username
Your admin user's unique API key as your Basic Auth password

You can find your account code by logging in to My Liftoff and going to Account Details.

You can generate, view, or regenerate your admin user's API key by logging in to My Liftoff and going to Profile.

❗️
Treat your API key as a password. Keep it secret.
Anyone who has access to your API key can view, create, update, or delete your Liftoff data, as supported by the API and your API key's permissions.
Your API key should never be included in client-side code or anywhere else that is publicly accessible.
As an extra precaution, we strongly recommend regenerating your API key on a regular basis.
