New features, enhancements, and fixes to the Vlens API and documentation

October 26, 2026

New features

Change Phone Number Session

Users can now change their registered phone number through an invitation link or an embedded session.

  • Admins with the new Change Phone Number Invitation permission can send an invitation from the Users page. The invitation is emailed, so the user’s email must be confirmed. English and Arabic email templates are included. See Users & invitations.
  • The user confirms the new number with an SMS code (OTP).
  • Users with a verified digital identity must also pass a face match against their stored biometric data. For other users, phone ownership is checked and the number is updated right after the OTP is verified.
  • The new number can’t be the same as the current number.

New endpoints under api/ChangePhoneNumberSession: CreateInvitation, CreateSession, GetUserSessionSettings, SendOtp, VerifyOtp and ValidateFaceMatch.

See Change Phone Number Session.

Prevent new request on rejection (iframe)

A new session permission, Prevent New Request On Rejection (sessionPermissions.preventNewRequestOnRejection), can be set when creating an invitation and is shown in the invitation and session details. When it is enabled, inside the iframe:

  • The user can’t start a new request for a contract type that was already rejected for them.
  • If every allowed contract type is already signed or rejected, the session is treated as fulfilled.

Rejected requests no longer count as signed contracts.

See Prevent new request on rejection and, for the portal, Users & invitations.

Signing status in contract emails

Contract emails now show who has signed: Customer Signed or Service Provider Signed. Two new placeholders are available for the email subject and body: {BUSINESS_REQUEST_TYPE} and {SIGNING_STATUS}.

The new default subject is:

{TENANT_NAME} - {BUSINESS_REQUEST_TYPE} - {SIGNING_STATUS}

See Contract emails.

Infobip base URL and sender name per tenant

The Infobip settings in the portal now include Base URL and Sender Name, and Test Connection uses them. The base URL can be entered without https://. Tenants that only saved an API key keep using the default base URL and sender. See Settings.

Enhancements

Faster, more stable contract PDFs

Contract PDF generation is faster and more stable under load.

Clear 404 for unknown endpoints

Calls to an endpoint that doesn’t exist now return HTTP 404 Endpoint not found instead of an authentication error. See HTTP error codes.

Bug fixes

  • Email matching in user lookups is no longer case-sensitive
  • Hidden or invisible characters and extra spaces are removed from the email or phone number before the user lookup
