SMS Retriever API

SMS Retriever API is an Android feature provided by Google that allows mobile apps to automatically retrieve one‑time passcodes (OTPs) from verification SMS messages without requiring users to manually enter the code or grant SMS read permissions. It is commonly used for login, signup, and two factor authentication 2FA flows in Android apps.

Developers often use the SMS Retriever API alongside services such as an SMS API to send verification messages that contain authentication codes.

How the SMS Retriever API Works

The SMS Retriever API allows Android apps to detect SMS verification messages that contain a one-time passcode. When a user requests a login or account verification, the app triggers a request to the server, which sends an SMS containing the OTP. the OTP.

Once the message arrives on the user’s device, Android automatically detects the verification code and passes it to the app. The code is then filled in automatically, allowing the user to complete the verification process without manually opening the SMS or typing the code.
 

SMS Retriever API and Notifyre

Notifyre can send SMS messages that work with Android’s automatic code‑reading feature.

Notifyre’s online SMS service will send the text message with the verification code. The Android phone and the customer’s app handle the rest behind the scenes. When the message arrives, Android recognises it as a verification message and automatically fills in the code for the user.

For the end user, this feels seamless:

• They receive a text message

• The app reads the code automatically

• They don’t need to copy, paste, or type anything

Notifyre doesn’t read messages or access phones, it simply delivers the SMS in the right format so Android apps can provide a smoother, faster login or sign‑up experience.
