Authentication

Get the API key for your project in Bannerbear and then instantiate a new client.

$bb = new Bannerbear\BannerbearClient("your api key");

Alternatively, set the API key in an environment variable named BANNERBEAR_API_KEY.

$bb = new Bannerbear\BannerbearClient();

Account Info

Return info about the account or project associated with the API key.

$account = $bb->account();

Images

Create an Image

To create an image you reference a template uid and a list of modifications. The default is async generation meaning the API will respond with a pending status and you can use get_image to retrieve the final image.

$bb->create_image("template uid", [
    "modifications" => [
        [
            "name" => "headline",
            "text" => "Hello world!",
        ],
        [
            "name" => "photo",
            "image_url" =>
            "https://images.unsplash.com/photo-1555400038-63f5ba517a47?w=1000&q=80",
        ],
    ],
]);

You can also create images synchronously - this will take longer to respond but the image will be delivered in the response:

$bb->create_image(
  "template uid",
  [
    "modifications" => [
        [
            "name" => "headline",
            "text" => "Hello world!",
        ],
        [
            "name" => "photo",
            "image_url" =>
            "https://images.unsplash.com/photo-1555400038-63f5ba517a47?w=1000&q=80",
        ],
    ],
  ],
  TRUE
);
