Google RCS Verify API

Dexatel’s Google RCS Verify API offers a modern, branded, and secure method for verifying users through Rich Communication Services (RCS). This channel combines the best of SMS and app-based messaging, allowing you to send one-time passcodes (OTPs) through verified, interactive RCS messages. With enhanced branding, real-time delivery status, and automatic fallback to SMS, WhatsApp, or Viber, Dexatel’s RCS verification offers a future-ready solution for businesses that prioritize both security and user experience.

Key Features

Verified Sender Branding: Messages appear to be from a verified business profile, featuring your brand name, logo, and colors, which enhances trust and reduces fraud risk.
Rich Message Format: Deliver OTPs using interactive RCS messages that support buttons, read receipts, and high-resolution visuals.
End-to-End Encryption: Messages are transmitted securely over IP with end-to-end encryption and verified sender authentication.
Automatic Fallback to SMS, WhatsApp, or Viber: If a recipient’s device or network doesn’t support RCS, the message automatically falls back to SMS, WhatsApp, or Viber to ensure delivery.
Real-Time Analytics: Gain insights into delivery, read status, and user interaction with each verification message.

Key Features

Initiate: Send a verification request to Dexatel’s API, including the recipient’s phone number and OTP code.
Message Sending: The API formats the code into a branded RCS message and sends it via the Android Messages app (or compatible client).
User Verification: The user receives the OTP and enters it into your app or interface. Optionally, a “Confirm” button may be used for simplified flows.
Completion: The code is validated via the API. If RCS delivery fails, the fallback logic automatically sends the OTP via SMS, WhatsApp, or Viber.

Benefits

Higher Conversion Rates: Rich, interactive messages lead to faster user action and fewer drop-offs during the verification process.
Enhanced User Trust: Verified business profiles reduce phishing risks and provide reassurance to users about message authenticity.
Cost-Effective with Smart Billing: Pay only for the successful delivery channel—no duplicate charges when fallback is used.
Seamless UX Across Devices: Consistent experience on Android devices supporting RCS, with fallback to ensure reach on all others.
Built-In Compliance: Fully compliant with telecom and data privacy regulations across supported regions.
