You can either create the token with your favourite JWT library or you can rely on our to create it for you. Note that if you need to create a lot of tokens at the same time, you may want to use a JWT library, since our API is rate-limited and you cannot execute thousands of requests per second.
Note the below examples are just for guidance - you are free to use any JWT library you are comfortable with or which your frameworks support. As you can see on the official - there are plenty of available libraries for each possible language.
The Java example is using the popular open source library.
The PHP example doesn't use external libraries, so it is a little bit more verbose.
