You do NOT pay for unsuccessful attempts, such as SMS sent, attempted text-to-speech (TTS) calls or even completed TTS calls that resulted in no successful verification.
To make the most of the “pay per conversion” model, tyntec recommends the following:
- Use tyntec as your primary — if not exclusive — verification partner
- Ensure that your application clearly explains to customers that the verification will occur, and ask for their consent to verify with a click-to-action button
- Once the customer has acknowledged he/she wants to start the verification, display a screen where the customer can enter the OTP.
