In order to use the API, you'll need to generate an API key that will be associated with your user. You can do this through the Snipe-IT web interface, by going to your account dropdown in the top right and clicking on "Manage API Keys".
If you run into an error when trying to create API tokens through the GUI, try running:
php artisan passport:install php artisan passport:client --personal
If you're planning on writing custom code to interact with the API or want to just use this interactive documentation to play with our development API, read on -- or get a quick start interacting with your API via Postman.
