Hi @Ahmed_Essam,

Based on the JWT you’ve provided, it seems that it hasn’t been signed with your SDK secret. Everything else looks correct, so once you sign it with the secret you should be all set!

Thanks!

Hi Jon,

Thanks for your response.

But i signed my jwt with my sdk secret

Here’s a screenshot from [jwt.io](http://jwt.io)

It says that my jwt signature is verified after adding the sdk secret

Please let me know if i am missing or misunderstood anything

Thanks.

Hi @Ahmed_Essam,

It looks like there may be a bug on [jwt.io](http://jwt.io), but I was able to verify that what you are seeing is correct. Can you please provide the encrypted SDK logs so that we can investigate further?

Thanks!
