Questions

Before you start

Can I send OTP codes from my app or website?

Yes. SMS OTP gives you an API to send verification codes for login, sign-up and payments, and Masters sends you documentation and test credentials.

Is there a WooCommerce plugin?

Yes. The free SMS Order Notifications plugin sends customers an SMS whenever their WooCommerce order changes status.

How long should an OTP message be?

Short enough to fit one SMS: 160 characters in English or 70 in Arabic. Anything longer is sent as several parts and counted as several messages, so code messages are best kept to one.

Connect in an afternoon

Tell us about your app or store and roughly how many codes you send. We'll send API access and a price.
