Set up Google Pay API

App prerequisites

Make sure that your app's build file uses the following values:

• A minSdkVersion of 19 or higher
• A compileSdkVersion of 28 or higher

Set up your app in your Google Pay account

• Install the Google Play services version 19.2.1 or greater.
• Install the Google Pay app and add a payment method.
• Add a payment method to Google.
• Adhere to our Google Pay API Acceptable Use Policy and the Google Play developer policy.

App dependencies

In your project-level build.gradle file, include Google's Maven repository and Maven central repository in both your buildscript and allprojects sections:

buildscript {
  repositories {
    google()
    mavenCentral()
  }
}

allprojects {
  repositories {
    google()
    mavenCentral()
  }
}
    

Add the Google Play services dependency for the Google Pay API to your module's Gradle build file, which is commonly app/build.gradle:

dependencies {
  implementation 'com.google.android.gms:play-services-wallet:19.2.1'
}
    

Modify your manifest

To enable Google Pay in your app, you need to add the following Google Pay API meta-data element to the <application> element of your project's AndroidManifest.xml file.

  
<meta-data
  android:name="com.google.android.gms.wallet.api.enabled"
  android:value="true" />
