Set up to authorize users

When users connect their Snyk account to your App, they must authorize access to their chosen Organization or Group and approve the requested scopes. This process starts when you direct users to the Snyk Apps authorization web page and pass the appropriate parameters: https://app.snyk.io/oauth2/authorize?response_type=code&client_id={clientId}&redirect_uri={redirectURI}&state={state}&code_challenge={codeChallenge}&code_challenge_method=S256

If your Snyk App is configured with multiple redirect URIs, passing redirect_uri will select which redirect URI to use. The given value must match exactly one of the values that are defined for your Snyk App. If not specified the first value defined on the Snyk App is used.

The state value is used to carry any App-specific state from this /authorize call to the callback on the redirect_uri (such as a user’s id). It must be verified in your callback to prevent CSRF attacks.

The code_challenge value is a URL-safe base64-encoded string of the SHA256 hash of a generated code verifier. This code verifier must be a highly randomised string generated on the app side before calling /authorize, the code verifier is sent when exchanging the returned authorization code for an access token. For more information see Proof Key for Code Exchange by OAuth Public Clients. Note that Snyk Apps only supports S256 for the code challenge method.

Authorize access to Organization

After the connection is complete, the user is redirected to the specified redirect URI with query string parameters code and state added on, which are necessary for the next step.
