TidyCal's REST API provides a handful of endpoints which can be used to get information about your account and bookings. It uses conventional OAuth 2.0 protocol for authentication.

Personal Access Token

Create a personal access token at https://tidycal.com/integrations/oauth. Once created, it can be used to authenticate requests by passing it in the Authorization header.

Authorization: Bearer {TOKEN}

OAuth 2.0 Client

If you're building a custom integration to TidyCal which requires users to authenticate in order to get access tokens to make API requests on their behalf, you'll need to create an OAuth 2.0 client. This is easy to do from the "OAuth Apps" settings page found here https://tidycal.com/integrations/oauth

Using the authorization_code grant type to authenticate users using OAuth 2.0 to retrieve an access token is fairly conventional, more information on that process can be found here: https://www.oauth.com/oauth2-servers/server-side-apps/authorization-code/
