Integrating your authentication provider with Dynamic

After configuring the settings, you can “sign-in” with a non-Dynamic JWT token by calling the appropriate method for your platform.

React

You can use the signInWithExternalJwt method from the useExternalAuth hook.

React

const { signInWithExternalJwt } = useExternalAuth();

try {
  // `externalUserId`: User ID in the external auth system
  // `externalJwt`: Raw encoded JWT issued by external auth system
  const userProfile = await signInWithExternalJwt({
    externalUserId,
    externalJwt
  });

  if (userProfile) {
    // You should be logged in at this point
  }
} catch (e: any) {
  console.error('Dynamic login failed:', e);
}

After this point, you can use the Dynamic SDK to access the user’s profile and other data, just as you would with any other user.

React Native

React Native provides external authentication through the dynamic client’s auth methods.

React Native

import { dynamicClient } from '<path to client file>';

try {
  // `externalUserId`: User ID in the external auth system
  // `externalJwt`: Raw encoded JWT issued by external auth system
  await dynamicClient.auth.external.signInWithExternalJwt({
    externalUserId,
    externalJwt
  });

  // You should be logged in at this point
} catch (e: any) {
  console.error('Dynamic login failed:', e);
}

After this point, you can use the Dynamic SDK to access the user’s profile and other data, just as you would with any other user.

Javascript

import { signInWithExternalJwt } from '@dynamic-labs-sdk/client';

const signIn = async (yourExternalJwt) => {
await signInWithExternalJwt({ externalJwt: yourExternalJwt });

  // User is now authenticated

};

Swift

Coming soon

Flutter

Flutter provides external authentication through the Dynamic SDK’s auth methods.

Flutter

import 'package:dynamic_sdk/dynamic_sdk.dart';

try {
  // `externalUserId`: User ID in the external auth system
  // `externalJwt`: Raw encoded JWT issued by external auth system
  await DynamicSDK.instance.auth.externalAuth.signInWithExternalJwt(
    SignInWithExternalJwtParams(
      externalJwt: externalJwt,
      externalUserId: externalUserId,
    ),
  );

  // You should be logged in at this point
} catch (e) {
  print('Dynamic login failed: $e');
}

After this point, you can use the Dynamic SDK to access the user’s profile and other data, just as you would with any other user.

You can also use verifyWithExternalJwt to verify a user:

Flutter

import 'package:dynamic_sdk/dynamic_sdk.dart';

try {
  await DynamicSDK.instance.auth.externalAuth.verifyWithExternalJwt(
    VerifyWithExternalJwtParams(
      externalJwt: externalJwt,
      externalUserId: externalUserId,
    ),
  );

  // User is now verified
} catch (e) {
  print('Verification failed: $e');
}
