OTP Verification Workflow

To implement OTP verification, follow these steps:

​
1. Send OTP

Use the /send-otp endpoint to send an OTP via SMS, WhatsApp, or Email. Supports:
  • Custom OTPs
  • SMS delivery via your own sender name registered with Authentica or default sender name offered by Authentica
  • Email delivery via your own email address registered with Authentica or default email address offered by Authentica
  • Control fallback channel, templates with ids 1 and 2 will be used for the fallback OTP based on the language of the main template you used in the request
Note: Check Application setting on Authentica dashboard to set default values for OTP options.

​

curl --location 'api.authentica.sa/api/v2/send-otp' \
