Simple class for making requests to the Trello API. Not affiliated with Trello or Atlassian.
use cjrasmussen\TrelloApi\TrelloApi;
$trello = new TrelloApi($key, $token);
// GET THE CARD DATA FOR A SPECIFIED LIST
$data = $trello->request('GET', "/1/lists/{$list_id}}/cards");
// MARK A SPECIFIED CARD AS ARCHIVED
$trello->request('PUT', "/1/cards/{$card_id}/closed", ['value' => true]);
More examples, as well as other things I've learned using the Trello API, are available at my blog.
Simply add a dependency on cjrasmussen/trello-api to your composer.json file if you use Composer to manage the dependencies of your project:
composer require cjrasmussen/trello-api
Although it's recommended to use Composer, you can actually include the file(s) any way you want.
