PHP SDK 400 bad request

I also have this frustrating issue. 
I docs there is clear format of JSON data then needs to be sent: https://developers.klaviyo.com/en/v1-2/docs/guide-to-integrating-a-platform-without-a-pre-built-klaviyo-integration#placed-order
 

But as soon as I reformat this data to PHP array format so I can use your PHP SDK package it returns error like this: 

'[400] Client error: `POST https://a.klaviyo.com/api/events/` resulted in a `400 Bad Request` response:

{"errors":[{"id":"22a89f30-3e98-4575-802b-572151897937","status":400,"code":"invalid","title":"Invalid input.","detail": (truncated...)

Please be advised this is not issue with API keys. This is error because of some field cannot be inserted.
I cannot know which since error msg is truncated! Please, please provide entire error message to end user, this is really poor decision to truncate error from user. I am now trying like chicken in a fog to find a way how can this be done.

Also in your PHP SDK docs, there should be clear indication and example or POST data that can be sent. It really, really simple for your DEV to add this examples of arrays to docs.
Without this thousands of DEV will lose thousands of hours researching this and nagging your support.

Anyway, can I have this secret data PHP array example data for placed order event? 
Just copy example array of data that needs to be posted and I will be on my way…
Thanks!

The issue still persists. I am using new PHP API SDK and I am having trouble with POST subscribeProfiles API. If I use Postman, with JSON body (which is decoded from the PHP body), I get 202 SUCCESS status. If I try the same data as an associative array in PHP, I get 400 status and the details parameter has “(truncated...)” value. Please help as this is a crucial piece of functionality my company is working on.

Hi @Plutarch87 Did you solve this issue? I have the same issue using the SDK for PHP
This is the error I got 
 KlaviyoAPI\ApiException  [400] Client error: `POST https://a.klaviyo.com/api/profiles/` resulted in a `400 Bad Request` response:
{"errors":[{"id":"a9080d30-8e7c-446e-b384-...","status":400,"code":"invalid","title":"Invalid input.","detail": (truncated...).

@Plutarch87 sorry for bothering you again but as you know the documentation lacks of information and I’m clueless how to implement the SDK.
I created a KlaviyoServiceProvider 

public function register()
    {
        $this->app->singleton(Klaviyo::class, function() {
            return new Klaviyo(new KlaviyoAPI($this->config['private_api_key']));
        });
    }

and then a Klaviyo service
 

 public function createKlaviyoProfile(User $user)
    {
        $body = array(
            "data" => array(
                "type" => "profile",
                "attributes" => array(
                    "email" => $user->email,
                    "phone_number" => $user->shipping_phone_number,
                    "external_id" => $user->id,
                    "first_name" => $user->firstName(),
                    "last_name" => $user->lastName(),
                    "organization" => null,
                    "title" => null,
                    "image" => null,
                    "location" => array(
                        "address1" => $user->shipping_address_line1,
                        "address2"=> $user->shipping_address_line2 ?? null,
                        "city" => $user->shipping_address_city,
                        "country" => "United States",
                        "region" => $user->shipping_address_state,
                        "zip" => $user->shipping_address_postal_code,
                        "timezone" => "America/New_York",
                    ),
                    "properties" => array(
                        "newKey" => "New Value",
                    ),
                ),
            ),
        );

        $klaviyo = new KlaviyoClient(
            $api_key = '$this->config['private_api_key']',
        );

        try {
            $klaviyo->Profiles->createProfile(json_encode($body));
        } catch (Exception $exception) {
            echo $exception;
        }
    }

Do you think this is a good approach?

Thank you @Plutarch87 I think I will switch to call it manually, is a shame the SDK does not work as suppose to!

I had the same issue as couldn’t figure out the format of the PHP associative array to pass (no examples seem to be given anywhere!).  

This is what I used to get it to work - hope it helps somebody!

 $body =['data' => ['type' => 'profile', 'attributes' => ['email' => 'test@outlook.com', 'first_name' => 'elliot',     'title' => 'fddfasdsfaf', 'organization' => 'fsdfdsfsd',    'external_id' => '1234', 'anonymous_id' => '12345', 'image' => 'dfds']]];

$klaviyo->Profiles->createProfile($body);
