VerifyKit is the next generation phone number validation system. Users can easily verify their phone numbers without the need of entering phone number or a pin code.
- Register your app at https://www.verifykit.com and get your client keys and server key.
- Add VerifyKit SDK to your app
- Configure and start VerifyKit SDK
- When verification completed, send "sessionId" which VeriyfKit SDK gives you to your backend service
- At your server side, get user's phone number from VerifyKit service wtih "serverKey" and sessionId. You can check Backend Integration
"ServerKey" are used for getting info from VerifyKit service. Please keep "ServerKey" safe. Do not include your client's code base.
Add it to your app build.gradle at the end of repositories:
implementation 'org.bitbucket.verifykit:verifykit-android:${lastVersion}'Add it to your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}Minimum SDK Version is api 16
In your Application file you should initialize VerifyKit. VerifyKit.init() method needs VerifyKitOptions object.
Application.kt
val theme = VerifyKitTheme(
backgroundColor = Color.WHITE
)
VerifyKit.init(
this,
VerifyKitOptions(
isLogEnabled = true,
verifyKitTheme = theme
)
)You can call VerifyKit.startVerification(this) method from your Activity or Fragment then get the result via VerifyCompleteListener interface from your Activity or Fragment.
VerifyKit.startVerification(this, object : VerifyCompleteListener {
override fun onSuccess(sessionId: String) {
// TODO operate SUCCESS process
}
override fun onFail(error: VerifyKitError) {
// TODO operate FAIL process
}
})Optional
You can pass user phone number to VerifyKit with startVerification method. In this way VerifyKit doesn't ask phone number to user
VerifyKit.startVerification(
activity = this,
countryPhoneCode = "+90",
phoneNumber = "5555555555",
mCompleteListener = object : VerifyCompleteListener {
override fun onSuccess(sessionId: String) {
// TODO operate SUCCESS process
}
override fun onFail(error: VerifyKitError) {
// TODO operate FAIL process
}
})VerifyKit.checkInterruptedSession
There may be a case when user chooses a third party messaging app for validation, sends a message, but doesn't return to main app and kills it. In that case, that user is verified with VerifyKit but the main app doesn't know it yet.
To fix this, we have a method to check interrupted session status.
VerifyKit.checkInterruptedSession(object : VerifyCompleteListener {
override fun onSuccess(sessionId: String) {
// sessionId
}
override fun onFail(error: VerifyKitError) {
// error
}
})Open the /app/manifest/AndroidManifest.xml file.
Add the following meta-data elements, an activity for VerifyKit and intent filter for App Link inside your application element:
<meta-data
android:name="com.verifykit.sdk.clientKey"
android:value="your_verifykit_client_key" />
<meta-data
android:name="com.verifykit.sdk.clientSecret"
android:value="your_verifykit_client_secret" />
<activity
android:name="com.verifykit.sdk.ui.VerificationActivity"
android:launchMode="singleInstance"
android:screenOrientation="portrait">
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:host="your_deep_link_url"
android:pathPattern="your_deep_link_pattern"
android:scheme="https" />
</intent-filter>
</activity>An Android App Link is a deep link based on your website URL that has been verified to belong to your website. So clicking one of these immediately opens your app if it's installed—the disambiguation dialog does not appear. Though the user may later change their preference for handling these links. For verifying your App Link see document
-keep class com.verifykit.sdk.core** { *; }
Depending on the language you use in your backend service, you can use one of the following options.
You can use our php-sdk like this;
$vfk = new \VerifyKit\VerifyKit($serverKey);
/** @var \VerifyKit\Entity\Response $result */
$result = $vfk->getResult($sessionId);
if ($result->isSuccess()) {
echo "Phone number : " . $result->getPhoneNumber() .
", Validation Type : " . $result->getValidationType() .
", Validation Date : " . $result->getValidationDate()->format('Y-m-d H:i:s') . PHP_EOL;
} else {
echo "Error message : " . $result->getErrorMessage() . ", error code : " . $result->getErrorCode() . PHP_EOL;
}You can use our python-sdk like this;
from VerifyKit import Verify
verify = Verify(server_key="{SERVER-KEY}")
verify.validation(session_id='{SESSION-ID}')
if verify.is_valid:
#Validation success.
print(verify.response())
elif verify.is_valid == False:
#Validation fail.
print(verify.response())
Or you can use curl request like this;
curl --location --request POST 'https://api.verifykit.com/v1.0/result' \
--header 'X-Vfk-Server-Key:{SERVER-KEY}' \
--header 'Content-Type: application/json' \
--form 'sessionId={{SESSION-ID}}’If you have any questions or requests, feel free to create an issue.
