Update phone number of end user by sending magic link via SMS

Update the phone number of an existing end user by sending a magic link to the new phone number. Descope will generate and deliver a clickable magic link as an SMS to the new phone number specified. After successfully verifying the magic link token the new phone number will be used to deliver new magic links via SMS.

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 bearer token requires both the ProjectId and refresh JWT in the format \<Project ID\>:<JWT>, and can therefore only be run for end users who are currently signed-in.

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.

Descope allows you to associating multiple login IDs for a user during API update calls. For details on how this feature works, please review the details here.

Next Step
