That looks like the right one. The function name is missing from the web page, but is in the download PDF and jar.

I found a download https://community.appian.com/b/appmarket/posts/jwt-web-token-tools#

the overview does not list the function I am using though! for JWT functions, I could not find the download.

I am confused! I was searching for the plugin JWT and do not find in App Market outside the plugins page. I either find JWT Tools or JWT functions however, none of them has the function I am using, Apparently, in Appian when I am trying to use, the function comes as part of JWT functions however, I added only JWT in plugins and registered that in third party... Its a little confusing how the plugins are maintained and it would have been useful if we had a central code repo for all the plugins. When I use other JWT Functions that are listed, the registered third party would not work!

If possible, Can you please direct me to the page where I can download the code?

Thank you.

The source code will be in the jar if you download the package directly from the AppMarket

oh Wow! I missed that completely! Fixed it and still working on the format. I can clearly see the base64 Python code uses is definitely different from what Appian plugin is creating. I don't have access to the source code of the plugin, checking for any available git for that plugin. Will post if I could fix it. Meanwhile any hints and guidance is appreciated. Thank you for all your support.

Additional hint - passing arguments by position is required for Appian custom function plug-ins (https://docs.appian.com/suite/help/23.2/passing-arguments.html#by-position). You might be missing alg as the 3rd argument, have typ and aud swapped, and have jti commented out.

I had to integrate to a different system and cannot help you with any Tableau details.

You will have to find your own way along the hints I posted. I think we asked the team that provided the keys to generate them in the format we needed.

Thank you . Can you please let me know what solution worked so I can try at my end?

Also, were you able to use the Embed API once you get the Signin API working?

I had similar issues in the past. The problem was with the key. That key can bei either as text, base64 encoded, or a binary representation. And the Appian plugin only works with one variant. I had downloaded the plugin and checked the source code to find out what exactly is going on.

After some trial and error I had it working.
