API ReferenceMagic LinkText Message (SMS)
POST
/v1/auth/magiclink/signin/sms

Initiate a sign-in process by sending a magic link to an existing end user. Descope will generate and deliver a clickable magic link as an SMS to the phone number specified. 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.

The endpoint will return a failure code if the email address is not registered.

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.
