Connect OAuth provider with Client Keys

Salt Edge now supports Account Information Services channels, which can be used with PSD2 and Open Banking compliant APIs. Read about it in Salt Edge Documentation.

1. Register application deep-link in Manifest.

     <activity
         android:name=".StartActivity">
   
         <intent-filter>
             <action android:name="android.intent.action.MAIN" />
             <category android:name="android.intent.category.LAUNCHER" />
         </intent-filter>
   
         <intent-filter android:label="@string/app_name">
             <action android:name="android.intent.action.VIEW" />
             <category android:name="android.intent.category.DEFAULT" />
             <category android:name="android.intent.category.BROWSABLE" />
             <!-- Accepts URIs that begin with "custom_scheme://custom_host/custom_path" -->
             <data
                 android:scheme="custom_scheme"
                 android:host="custom_host"
                 android:pathPattern="/custom_path"/>
         </intent-filter>
     </activity>

2. Init SDK with returnToUrl as application deep-link

     String returnToUrl = "custom_scheme://custom_host/custom_path";
   
     SaltEdgeSDK.getInstance().init(
         applicationContext, 
         clientAppId, 
         clientAppSecret, 
         returnToUrl
     );

3. Fetch providers and select one

4. Create Connect Session

5. Open received connectUrl in external app

       private void loadConnectUrl(String connectUrl) {
           if (provider.isOAuth()) {
               this.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(connectUrl)));//Open in external app
           } else {
               SEWebViewTools.getInstance().initializeWithUrl(this, webView, connectUrl, this);//Open in WebView
           }
       }

6. All connect operations (Authorizations, Fetching, etc.) will be performed in external app.

7. If deep-link is received (bu Activity declared in Manifest), then extract customer_secret from params.

       String dataString = getIntent().getDataString();
       if (dataString != null) {
           Uri uri = Uri.parse(dataString);
           String connectionSecret = uri.getQueryParameter(Constants.KEY_CONNECTION_SECRET);
           if (connectionSecret != null && !connectionSecret.isEmpty()) {
               //Save received `connection secret` for future operations
           }
       }
