**Description**
I am trying to test Zoom Android SDK and followed the exact steps stated here: [https://marketplace.zoom.us/docs/sdk/native-sdks/android/getting-started/install-sdk](https://marketplace.zoom.us/docs/sdk/native-sdks/android/getting-started/install-sdk)
However, I still encountered error code: 1 i already used SDK Keys & SDK Secret on marketplace zoom. is it my sdk keys & secret that problem or my JWT Token?
**Screenshots**
**Smartphone (please complete the following information):**
- Device: Galaxy Note 9
- OS: Android 10
Thank you so much

Hi [rizkyrayd](https://devforum.zoom.us/u/rizkyrayd),
Thanks for using Zoom SDK. If you would like to use JWT token for SDK authentication, please make sure you are following the instructions in [https://marketplace.zoom.us/docs/sdk/native-sdks/android/mastering-zoom-sdk/sdk-initialization](https://marketplace.zoom.us/docs/sdk/native-sdks/android/mastering-zoom-sdk/sdk-initialization) and make sure you are using SDK key&secret(Not API key or OAuth token) from Marketplace to generate the JWT token.
You may refer to the implementation in our demo app: [https://github.com/zoom/zoom-sdk-android/blob/master/mobilertc-android-studio/sample/src/main/java/us/zoom/sdksample/initsdk/InitAuthSDKHelper.java](https://github.com/zoom/zoom-sdk-android/blob/master/mobilertc-android-studio/sample/src/main/java/us/zoom/sdksample/initsdk/InitAuthSDKHelper.java)
Hope this helps. Thanks!

Hi [rizkyrayd](https://devforum.zoom.us/u/rizkyrayd),
Thanks for the reply. The JWT token is optional, you may choose to use SDK key&secret directly or generate the JWT token from your SDK key&secret and use it for initialization.
You should be able to create SDK app and get SDK key&secret with any license type.
Hope this helps. Thanks!

in sample apps that zoom shared on github,there’s a AuthConstants and have string SDK SDK\_JWTTOKEN what should i do if i dont use JWT? do i have to comment it or what? one thing there’s a WEB\_DOMAIN and the default is “[zoom.us](http://zoom.us)” is it the problem that my zoom sdk cannot connect/initialize?

Hi [rizkyrayd](https://devforum.zoom.us/u/rizkyrayd),
Thanks for the reply. There are fields in the InitParam for the SDK key & secret.
If you would like to use SDK key & secret directly, or to check whether your SDK key and secret are working or not, you may comment out the field for JWT token and add the following:
```auto
ZoomSDKInitParams initParams = new ZoomSDKInitParams();
// initParams.jwtToken = SDK_JWTTOKEN;
initParams.appKey = SDK_KEY;
initParams.appSecret = SDK_SECRET;
...
```
It is recommended to use JWT token instead of using SDK key & secret directly as it is not secure and provides more flexibility. You may refer to the doc to generate the correct JWT token: [https://marketplace.zoom.us/docs/sdk/native-sdks/android/mastering-zoom-sdk/sdk-initialization](https://marketplace.zoom.us/docs/sdk/native-sdks/android/mastering-zoom-sdk/sdk-initialization)
Thanks!

Hey @rizkyrayd,
This most likely means you do not have a [Pro or above Zoom plan](https://zoom.us/pricing).
In order to develop with the [Web SDK](https://marketplace.zoom.us/docs/sdk/native-sdks/web), you need to upgrade your plan. You can request a free trial here: [isv@zoom.us](mailto:isv@zoom.us)
Also for the Web SDK, you must use [JWT Credentials](https://marketplace.zoom.us/docs/sdk/native-sdks/web/getting-started/integrate) instead of SDK credentials.
Thanks,
Tommy

Hey @rizkyrayd,
You need to put your JWT App Key and Secret here:

Hey @rizkyrayd, happy to hear Web SDK is working! 🙂
For the Android issue, have you tried using [SDK App credentials](https://marketplace.zoom.us/docs/guides/getting-started/app-types/create-sdk-app)?

Hey @rizkyrayd,
Can you create a new topic in the [Android category](https://devforum.zoom.us/c/mobile-sdk/android) so our Android developers can assist you?
Thanks,
Tommy
