+# Iden3Message Parser
+
+## Introduction
+
+With the latest update, the content of the QR code provided by the Issuer or Verifier could be in three different formats:
+- Url (iden3comm://?request_uri=)
+- Base64 encoded (iden3comm://?i_m=)
+- RAW Json format (json)
+
+## Code Snippet
+to parse the qr code content, you can use the following code snippet as an example:
+
+```dart
+class QrcodeParserUtils {
+  final PolygonIdSdk _polygonIdSdk;
+
+  QrcodeParserUtils(this._polygonIdSdk);
+
+  Future<Iden3MessageEntity> getIden3MessageFromQrCode(String message) async {
+    try {
+      String rawMessage = message;
+      if (message.startsWith("iden3comm://?i_m")) {
+        rawMessage = await _getMessageFromBase64(message);
+      }
+
+      if (message.startsWith("iden3comm://?request_uri")) {
+        rawMessage = await _getMessageFromRemote(message);
+      }
+
+      Iden3MessageEntity? _iden3Message =
+      await _polygonIdSdk.iden3comm.getIden3Message(message: rawMessage);
+      return _iden3Message;
+    } catch (error) {
+      throw Exception("Error while processing the QR code");
+    }
+  }
+
+  Future<String> _getMessageFromRemote(String message) async {
+    try {
+      message = message.replaceAll("iden3comm://?request_uri=", "");
+      http.Response response = await http.get(Uri.parse(message));
+      if (response.statusCode != 200) {
+        throw Exception("Error while getting the message from the remote");
+      }
+      return response.body;
+    } catch (error) {
+      throw Exception("Error while getting the message from the remote");
+    }
+  }
+
+  Future<String> _getMessageFromBase64(String message) async {
+    try {
+      message = message.replaceAll("iden3comm://?i_m=", "");
+      String decodedMessage = String.fromCharCodes(base64.decode(message));
+      return decodedMessage;
+    } catch (error) {
+      throw Exception("Error while getting the message from the base64");
+    }
+  }
+}
+```
