Please kindly assist. Each time we want to join meeting when using the web sdk we always receive Signature Invalid. kindly guide me on how to resolve the issue.

Are you using the component view or client view SDK? Can you provide some more info about how you are generating the signature and what you are passing in the join function call?

var signature = ZoomMtg.generateSDKSignature({ meetingNumber: meetingConfig.mn, sdkKey: CLIENT_ID, sdkSecret: CLIENT_SECRET, role: meetingConfig.role, success: function (res) { meetingConfig.signature = res.result; meetingConfig.sdkKey = CLIENT_I…

In my implementation, I used the following function to generate the working signature: function generateSignature(apiKey, apiSecret, meetingNumber, role) { const iat = Math.round(new Date().getTime() / 1000) - 30; const exp = iat + 60 * 60 * 2; const oHeader = { alg: "HS256", typ: "JWT" }; …

Thanks for the code. Does your code also prevent “The Signature has expired” error and suddenly the meeting ends

Haven’t seen that in my case, but note this line in the code: const iat = Math.round(new Date().getTime() / 1000) - 30; is based on the current time of the computer or server the code is running on. Is it possible the time is not correct and so when it reaches Zoom servers it shows the signature a…

please explain in details: const iat = Math.round(new Date().getTime() / 1000) - 30;

Hi @c.egeolu , here is more details about math.round potential issue: [image] Randomly getting "Signature is invalid" error Web Found that Math.round() returning a timestamp which is randomly 10-30sec more with actual value. After removing it, things started working fine…

@c.egeolu The signature attribute is based on JSON Web Tokens. In JWT, the iat attribute indicates when the token was issued (which in my implementation was the current timestamp minus 30 seconds to avoid issues with round, like the one @gianni.zoom posted). Based on iat, the exp attribute is calcu…

Can you please share a complete working sample code using javascript to generate the signature without using JWT and removing the using Math.round()
