Set up your C2 account with OAuth credentials

Visit the OAuth applications manager URL for the site you want to use. In production, that would be https://cap.18f.gov/oauth/applications -- the endpoint is the same regardless of the environment or hostname.

Create a new application.

Authorize the new application (click the Authorize button).

Use the key/secret pair generated for your client configuration.
