Overview

Creating and verifying a mobile number for your customer is a crucial step in the customer onboarding process. With a verified mobile number, customers can use SMS OTPs to complete two-factor authentication (2FA) challenges.

This guide explains how Solaris handles customers' mobile numbers and contains a list of standardized SMS messages to send to your customers in various situations.

note

Verified mobile numbers are required for customers in all branches.

How Solaris stores mobile numbers

The Solaris API represents a customer's mobile number in the form of a mobile_number resource, which is a separate resource from the person resource. The mobile_number resource has a set of dedicated API endpoints.

The person resource has a mobile_number attribute. Note that this is not linked to the respective mobile_number resource. Your solution should always use the mobile_number resource instead of the mobile_number attribute on the person resource.

Each person may only have one verified mobile number. If you attempt to add another mobile number to a person with a verified mobile number, then the API will respond with a 409 error.

On every endpoint, Solaris' API sanitizes mobile numbers before validating them against the E.164 standard. You should always use the mobile number returned by our API.

SMS OTP lifecycle

Solaris enables customers to use SMS OTP as a method for authentication two-factor authentication (2FA) challenges for actions such as logging in and completing change requests.

See the Strong Customer Authentication guide for information about how to implement SMS OTP in your solution.

List of SMS OTP texts

This table contains standardized texts to send to customers in SMS OTP messages. You may not deviate from these texts without Solaris' express permission.

Note the use of variables throughout the text. Substitute each variable in the text with a placeholder for the corresponding value (e.g., a placeholder for the SMS OTP in each instance of OTP).

Solaris will automatically send the text in the customer's preferred language if you have created a language preference for the customer.
