Stytch - Auth platform for developers

B2B Saas Authentication

Frontend SDKs

Headless

Multi-Factor Authentication

One-Time Passcodes

SMS Send

The SMS Send method wraps the send via SMS API endpoint. Call this method to send an SMS passcode to an existing Member.

If a Member has a phone number and is enrolled in MFA, then after a successful primary authentication event (e.g. email magic link authenticate or SSO authenticate is complete), an SMS OTP will automatically be sent to their phone number. In that case, this endpoint should only be used for subsequent authentication events, such as prompting a Member for an OTP again after a period of inactivity.

Cost to send SMS OTP

Before configuring SMS or WhatsApp OTPs, please review how Stytch bills the costs of international OTPs and understand how to protect your app against toll fraud.
