POST
/v1/auth/magiclink/signup-in/email

Initiate a process that implements both sign-in and sign-up using a single endpoint. Descope will generate and deliver a clickable magic link to the email address specified. If the email address is already registered (the end user has already registered) the user will be signed in. If the email address is not registered (the end user is not yet registered) the user will be signed up.

The clickable magic link is made up of two parts - the URI you provide in the URI field and the magic link token generated by Descope. For example, if URI=https://app.mycompany.com/magiclink/verify, the clickable magic link will be https://app.mycompany.com/magiclink/verify?t=magic-link-token. Magic links expire in the time frame configured in the Descope console, so sending multiple magic links (for example, when an end user tries to sign-up a second or third time) does not invalidate prior magic links that have already been sent.

Note that URI is an optional parameter. If omitted - the project setting will apply. If provided - it should to be part of the allowed Approved Domains configured in the project settings.

Next Steps

Verify the magic link token using the Verify Token endpoint.
