Thinkific OAuth VueJS Starter

This is an example of how to setup a Vue.JS application to request access_token from a Thinkific Site.

Prerequisites

You will need the credentials for your app created in Thinkific Platform.

• client_id: App's client id;
• redirect_uri: App's registered callback uri. For this project will be your app's url + /callback.

Description

The project uses OAuth authorization code flow with Proof of Key for Code Exchange (PKCE) to retrieve the access_token.

This flow is recommended when storing app's client_secret is not safe.

The application generates a cryptographically random string called code_verifier. The code_challenge is created from the code_verifier using SHA256 and converting to base64 urlsafe.

First the Authorize link will redirect the user to the Thinkific Site with:

• client_id: app's client_id
• response_type: code (informs that the flow to exchange the access_token will be authorization_code flow)
• redirect_uri: app's url + /callback
• code_challenge: base64urlsafe(sha256(codeVerifier))
• code_challenge_method: S256 (method used to generate the challenge)
• state: state parameter - optional

Once the user gives their consent to the application, Thinkific will redirect the authorization code to the redirect_uri, in our case, the /callback route.

The application then retrieves the code and executes the token request sending the code_verifier, code and grant_type. Thinkific validates the code and code_verifier and respond with the access_token which then the application can use to invoke Thinkific's API.
