I’m trying to test meeting-sdk. It was not working with correct SDK key it throws **Invalid sdkkey** error in the dev console. I used the below link for Web Meeting SDK: > **[Getting Started](https://marketplace.zoom.us/docs/sdk/native-sdks/web/build/#option-2-import-through-cdn)** > > The Zoom Developer Platform is an open platform that allows third-party developers to build applications and integrations upon Zoom’s video-first unified communications platform. For join meeting I am using client.join() function. client.join({ sdkKey: “xxxxxx”, signature: “xxxxx”, meetingNumber: xxxxx, password: xxxx, userName: “xxxxx”, userEmail: “”, zak: “xxxxx” }) Please let me know if I’m missing anything here. ---

the usual question at the time when zoom login (-\> Signature, key error) is not functioning is: which method is used for the signature? (1) JWT Signature (deprecated) (2) SDK JWT Signature You can not mix both methods try the examples on github > **[GitHub - zoom/meetingsdk-web-sample: Zoom Meeting SDK Web Sample App](https://github.com/zoom/meetingsdk-web-sample)** > > Zoom Meeting SDK Web Sample App. Contribute to zoom/meetingsdk-web-sample development by creating an account on GitHub. all examples on github zoom with version 2.3 and higher uses SDK JWT Signature all examples on github zoom with version 2.2 and lower uses JWT Signature Jürgen ---

@mpzoomuser, Please share a screenshot of what you are seeing. Also, you can use our sample app to generate the token and manually place the token in the property. This will allow you to isolate where the issue may be. > **[GitHub - zoom/meetingsdk-sample-signature-node.js: Generate a signature to...](https://github.com/zoom/meetingsdk-sample-signature-node.js)** > > Generate a signature to Start and Join Meetings and Webinars with the Zoom Meeting SDKs. - GitHub - zoom/meetingsdk-sample-signature-node.js: Generate a signature to Start and Join Meetings and Web... ---

I’m using c# to generate the SDK JWT. method: ‘join’, status: false, result: ‘Invalid sdkkey.’, errorMessage: ‘Fail to join the meeting.’, errorCode: 1 ---

@mpzoomuser Currently, we do not have a sample app for C#. However, you can deploy our sample app and just make a request to the endpoint to get the correct signature. ## Generate the SDK JWT [https://marketplace.zoom.us/docs/sdk/native-sdks/auth/#generate-the-sdk-jwt](https://marketplace.zoom.us/docs/sdk/native-sdks/auth/#generate-the-sdk-jwt) ---

I do not need a sample app. I’m able to generate the SDK JWT, however, when I join using that token then I get the invalid sdkkey error. If you would like I can share the JWT token in a private chat. ---

@mpzoomuser , Based on the information, either you are generating the signature wrong or you are not using the correct sdkKey. If the former, I’d recommend using the sample app to correctly generate the signature. If the latter, double checking you are using the correct sdkKey. Please share a screenshot of the exact error you are seeing in the dev console. ---

did you checked your SDK JWT Token with the sample app? there is a very good tutorial on youtube [![](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/0/5/054d5a50d5aea1cc33012ca06709ae571ed7994b.jpeg "Zoom Meeting SDK Tutorial") ](https://www.youtube.com/watch?v=fMIXcLlBwZ0) ---
