Why do I get a 400 Bad Request error from api
I am trying to call a shiplogic API (based in AWS), but I get 400 Bad Request error.
I have tried various ways to request response from the AWS API such as S3, I have tried creating my own signature for a cURL request, and now I am trying this code.
$host = "api.shiplogic.com";
$accessKey = 'AKIA55D****';
$secretKey = 'cx0WDJLNj1Bmn2**';
$requestUrl = 'https://api.shiplogic.com';
$uri = '/tracking/shipments';
$httpRequestMethod = 'GET';
$data = '{"tracking_reference": "M3RPH"}';
require 'AWS/aws-autoloader.php';;
use Aws\Signature\SignatureV4;
use Aws\Credentials\Credentials;
use GuzzleHttp\Client;
use GuzzleHttp\Psr7\Request;
use Psr\Http\Client\ClientInterface;
$signature = new SignatureV4('execute-api', 'af-south-1');
$credentials = new Credentials($accessKey, $secretKey);
$psr7Request = new Request($httpRequestMethod, $requestUrl.$uri, ["content-type"=>"application/json"], $data);
$client = new Client([$requestUrl, 'timeout' => 30]);
$sr = $signature->signRequest($psr7Request, $credentials);
$response = $client->send($sr);
var_dump($response);
The short error is: PHP Fatal error: Uncaught GuzzleHttp\Exception\ClientException: Client error: GET https://api.shiplogic.com/tracking/shipments resulted in a 400 Bad Request response: Invalid or incomplete input
The full error is:

Solution
The documentation says that
you need to pass the tracking_reference parameter on the query string (just as you did with Postman):
https://api.shiplogic.com/tracking/shipments?tracking_reference=G9G
But that's not what your code does:
$data = '{"tracking_reference": "M3RPH"}';
$psr7Request = new Request($httpRequestMethod, $requestUrl.$uri, ["content-type"=>"application/json"], $data)
The exception message clearly shows that the parameter is missing from the URL:
`GET https://api.shiplogic.com/tracking/shipments` resulted in a `400 Bad Request` response
You should do something like this instead:
$psr7Request = new Request($httpRequestMethod, $requestUrl.$uri.'?tracking_reference=M3RPH');
