To use the Otter Waiver APIs, you need to sign up here.
Follow the steps below after sign up to obtain the credentials for API authentication.
Your Client ID and Client Secret carry many privileges, so be sure to keep them secure! Do not share your secret API keys in publicly accessible areas such as GitHub, client-side code, and so forth.
All API requests must be made over HTTPS. Calls made over plain HTTP may fail. API requests without authentication will also fail.
After your account is properly setup and you have access to the api credentials, the next step is to obtain an Authorization token to authorize all requests towards all other endpoints.
