BraintreeHttp is a generic HTTP Client.

In it's simplest form, an HttpClient exposes an execute method which takes an HTTP request, executes it against the domain described in an Environment, and returns an HTTP response.


An Environment describes a domain that hosts a REST API, against which an HttpClient will make requests. Environment is a simple interface that wraps one method, baseUrl.

$env = new Environment('');


HTTP requests contain all the information needed to make an HTTP request against the REST API. Specifically, one request describes a path, a verb, any path/query/form parameters, headers, attached files for upload, and body data.


HTTP responses contain information returned by a server in response to a request as described above. They are simple objects which contain a status code, headers, and any data returned by the server.

$request = new HttpRequest("/path", "GET");
$request->body[] = "some data";

$response = $client->execute($req);

$statusCode = $response->statusCode;
$headers = $response->headers;
$data = $response->result;


Injectors are blocks that can be used for executing arbitrary pre-flight logic, such as modifying a request or logging data. Injectors are attached to an HttpClient using the addInjector method.

The HttpClient executes its injectors in a first-in, first-out order, before each request.

class LogInjector implements Injector
    public function inject($httpRequest)
        // Do some logging here

$logInjector = new LogInjector();
$client = new HttpClient($environment);

Error Handling

HttpClient#execute may throw an Exception if something went wrong during the course of execution. If the server returned a non-200 response, IOException will be thrown, that will contain a status code and headers you can use for debugging.

catch (HttpException $e)
    $statusCode = $e->response->statusCode;
    $headers = $e->response->headers;
    $body = $e->response->result;
