In my Laravel application, I periodically need to POST data to an API using Guzzle 6.0.
The API users a bearer token to authenticate, and requests and accepts raw json. To test, I accessed the API using Postman, and everything worked wonderfully.
And Postman Body:
"request1" : "123456789",
"request2" : "2468",
"request3" : "987654321",
"name" : "John Doe"
Postman returns a 200, and a JSON object as a response.
Now, when I try the same with Guzzle, I get a 200 status code, but no JSON object gets returned. Here's my Guzzle implementation:
public function getClient($token)
return new Client([
'base_uri' => env('API_HOST'),
'Accept' => 'application/json',
'Authorization' => 'Bearer ' . $token,
'Content-Type' => 'application/json'
$post = $client->request('POST', '/path/to/api', [
'json' => [
'request1' => 123456789,
'request2' => 2468,
'request3' => 987654321,
'name' => 'John Doe',
Is there some trick to POSTing JSON with Guzzle? If not, is there a way to debug what's going on under the hood?
I cannot, for the life of me, understand what the difference is between the Postman POST and the Guzzle POST.
