message, do as follows:cd ios && pod update IdensicMobileSDK && cd ..
- Update
Info.plist
to have a description for the usage of the camera, microphone, photo library and geolocation:
plutil -insert "NSCameraUsageDescription" -string "Let us take a photo" ios/${PWD##*/}/Info.plist
plutil -insert "NSMicrophoneUsageDescription" -string "Time to record a video" ios/${PWD##*/}/Info.plist
plutil -insert "NSPhotoLibraryUsageDescription" -string "Let us pick a photo" ios/${PWD##*/}/Info.plist
plutil -insert "NSLocationWhenInUseUsageDescription" -string "Please provide us with your geolocation data to prove your current location" ios/${PWD##*/}/Info.plist
Modules
MRTDReader (NFC)
The MRTDReader
is a module that allows the SDK to detect and read the electronic chips placed on MRTD documents via NFC.
For Android, the module comes out of the box. To enable the module for iOS, follow the instructions below:
- Update
ios/Podfile
.
# Enable MRTDReader (NFC) module
ENV['IDENSIC_WITH_MRTDREADER'] = 'true'
- Ensure the
OpenSSL-Universal
dependency to be included in release builds. TheMRTDReader
module depends on theOpenSSL-Universal
internally but starting off React Native 0.67, the Flipper extension forces theOpenSSL-Universal
not to be included in the Release builds, so you have to either stop using Flipper or use the following workaround.
use_flipper!()
# Ensure `OpenSSL-Universal` dependency to be included in Release builds
if ENV['IDENSIC_WITH_MRTDREADER']
pod 'OpenSSL-Universal', :configurations => ['Debug', 'Release']
end
- Open up the iOS project in XCode.

Usage
Attention
Before launching, make sure you have configured your verification level and access token.
Setup
import SNSMobileSDK from '@sumsub/react-native-mobilesdk-module';
// ...
let launchSNSMobileSDK = () => {
// From your backend get an access token for the applicant to be verified.
// The token must be generated with `levelName` and `userId`,
// where `levelName` is the name of a level configured in your dashboard.
//
// The sdk will work in the production or in the sandbox environment
// depend on which one the `accessToken` has been generated on.
//
let accessToken = "your_access_token";
let snsMobileSDK = SNSMobileSDK.init(accessToken, () => {
// this is a token expiration handler, will be called if the provided token is invalid or got expired
// call your backend to fetch a new access token (this is just an example)
return fetch('http://example.org/', {
method: 'GET',
}).then(resp => {
// return a fresh token from here
return 'new_access_token'
})
})
.withHandlers({ // Optional callbacks you can use to get notified of the corresponding events
onStatusChanged: (event) => {
console.log("onStatusChanged: [" + event.prevStatus + "] => [" + event.newStatus + "]");
},
onLog: (event) => {
console.log("onLog: [Idensic] " + event.message);
}
})
.withDebug(true)
.withLocale('en') // Optional, for cases when you need to override the system locale
.build();
snsMobileSDK.launch().then(result => {
console.log("SumSub SDK State: " + JSON.stringify(result))
}).catch(err => {
console.log("SumSub SDK Error: " + JSON.stringify(err))
});
}
The snsMobileSDK.launch()
returns a Promise
that will be resolved with the Result object. Use it to determine the SDK status upon its closure.
Here is an example of the result
:
{
"success": false,
"status": "Failed",
"errorType": "Unauthorized",
"errorMsg": "Unauthorized access with accessToken=[your access token]"
}
Launch
Next, you are able to use the launchSNSMobileSDK()
, as defined above to launch the SDK.
For example.
<Button onPress={launchSNSMobileSDK} title="Launch SumSub SDK" />
Dismissal
By default, once the applicant is approved the SDK will be dismissed in 3 seconds automatically. You can adjust this time interval or switch the automatic dismissal off by setting value of zero.
snsMobileSDK.withAutoCloseOnApprove(0)
Also, in case you need to close the SDK programmatically, here is the what you can do.
snsMobileSDK.dismiss()
Advanced
Configuration
If it is required, you can provide an email and/or phone number that will be assigned to the applicant initially.
.withApplicantConf({
"email": "...",
"phone": "..."
})
Preferred documents
For IDENTITY*
steps, it is possible to specify the preferred country and document type to be selected automatically, bypassing the DocType Selector
screen.
Note that the parameters provided will be applied only if the corresponding combination of country and idDocType
is allowed at the step according to the level configuration.
.withPreferredDocumentDefinitions({
"IDENTITY": {
"idDocType":"PASSPORT",
"country":"USA"
},
"IDENTITY2": {
"idDocType":"DRIVERS",
"country":"FRA"
}
})
Disable Google ML Kit
Attention
This is an Android-specific feature.
The SumSub SDK uses Google ML Kit face detection library if it is available with the application and builtin Android face detection otherwise. You can disable using ML Kit even if it is available.
.withDisableMLKit(true)
Localization
You can customize or localize the texts used within the SDK through the MSDK Translations tool in the dashboard.
The language of the texts will be set according to the system locale, but you could override it with the locale you desire.
.withLocale("en")
For a complete list of supported locales, see this article.
Strings
In addition to the MSDK Translations tool and .withLocale
, you can use .withStrings
option that allows you to define the strings locally.
This may be helpful for iOS apps if you would like to avoid the Wordless Oops screen that could be rendered in case the network happens to be down during the SDK initialization and force the SDK to draw the Network Oops screen instead.
.withStrings({
"sns_oops_network_title": "Oops! Seems like the network is down.",
"sns_oops_network_html": "Please check your internet connection and try again.",
"sns_oops_action_retry": "Try again",
})
Note that .withLocale
does not affect these strings, thus it is up to you to use the required localization.
Analytics
The SDK collects and sends usage data to Sumsub servers. We do not track any sensitive data. Only general usage statistics is sent to us. It includes screen navigation events, UI controls interaction events and so on.
We interpret the usage data in order to improve Sumsub. None of the data is sold or transferred to third parties, and we do not use it for advertisement.
If you still want to disable this feature, you can use the following to do this:
.withAnalyticsEnabled(false)
Events
Various events happening along the processing could be delivered into an optional onEvent
handler:
.withHandlers({
onEvent: (event) => {
console.log("onEvent: " + JSON.stringify(event));
}
})
Each Event has eventType
and some parameters packed into payload
hash, for example:
{
"eventType": "StepInitiated",
"payload": {
"idDocSetType": "IDENTITY"
}
}
Possible events
eventType | payload | Description | |
---|---|---|---|
"ApplicantLoaded" | { | The applicant $applicantId has been loaded. | |
"StepInitiated" | { | Step $idDocSetType has been initiated. | |
"StepCompleted" | { | true } | Step $idDocSetType has been fulfilled or cancelled. |
"Analytics" | { | Analytics event $eventName has occurred. |
Applicant Actions
To run the iOS SDK in Applicant actions mode, you need to have:
- A verification level with the Applicant actions type.
- An access token created with the
userId
,levelName
, andexternalActionId
parameters.
Aside from the notes above, use the SDK the same way that you do with regular levels, but the further processing may differ depending on the action type.
The action type is configured for a particular level in the Dashboard and can be one of the following:
Additional Verification
Additional verification actions are processed completely identically to the regular level verifications. You configure and manage the SDK the same way. Nothing special is required.
Attention
The
Payment methods
step is not supported at the moment.
Face Auth
Face authentication actions are handled in a specific manner. The user is taken to the FaceScan (Liveness) screen directly and once the action is complete, the SDK will be automatically closed.
When an action is completed, the status
will be set to ActionCompleted
and the result structure would contain the actionResult
field that describes the outcome of the last action invocation.
{
"success": true,
"status": "ActionCompleted",
"actionResult": {
"actionId": "5f77648daee05c419400c572",
"answer": "GREEN"
}
}
An empty value of actionResult.answer
means that the action was cancelled.
Action result handler
In addition, for Face Auth actions, there is an optional onActionResult
handler that allows you to handle the action results upon its arrival from the backend.
The user sees the Processing... screen at this moment.
.withHandlers({
onActionResult: (result) => {
console.log("onActionResult: " + JSON.stringify(result));
// you must return a `Promise` that in turn should be resolved with
// either `cancel` to force the user interface to close, or `continue` to proceed as usual
return new Promise(resolve => {
resolve("continue");
})
}
})
