If you already have token generation and validation logic and would like to keep those systems in place, you can do so. We have a feature where you can submit your code to us and utilize our pre-screened message templates and localizations for both text and voice.
If you're using custom verification codes you must also provide feedback that lets us know whether or not the user verified the code. This allows us to proactively monitor our global routing and stay operational.
By default, the company name that the end user sees in a verification message is set at the service level. You can programmatically override this by setting the
custom_friendly_name parameter when creating verifications. Custom company names may be useful for Independent Software Vendors (ISVs) who own one Verify Service and need to customize the company name for each verification message.
