JWT Decode - Yaak Plugin

Decoding a JWT by hand — copying the token, heading to jwt.io, pasting it in, and hunting for the claim you need — breaks your flow every single time. To make things simpler, I wrote this little plugin for the Yaak API client which provides a template function to decode any JWT token and optionally filter the result using a JSONPath expression.

Basic Usage

To use this plugin, proceed as follows:

1. In Yaak, go to Settings > Plugins, search for JWT Decode and hit Install.
2. Open any request and go to the tab where you need the decoded value (e.g. Headers, Body, or Query).
3. In the value field, start typing jwt.decode and select the corresponding function.
4. Click on the template and paste in your JWT token.
5. Optionally, provide a JSONPath expression (e.g. $.data.login) to extract a specific field.

That's it!
