README

This package is an SDK for the GraphQL API.

Basics

The SDK on GitHub

Minimal PHP version: ^8.2

Requires GuzzleHttp ^7.7.0

For Laravel projects we recommend using the Laravel providers for REST or GraphQL.

Installation

You can install the SDK as a composer package.

composer require preprio/php-graphql-sdk

Making your first request

Let's start with getting some content items from your Prepr environment.

<?php

use Preprio\Prepr;

$apiRequest = new Prepr('{ENDPOINT_URL}');

$apiRequest
    ->rawQuery('{
                  Posts( limit : 30 ) {
                    items {
                        _id
                        _slug
                        title
                    }
                  }
                }')
    ->request();

print_r($apiRequest->getResponse());

In the example above, we wrote all of our arguments inside the query string. However, in most applications, the arguments to fields will be dynamic. To add these properties, use the variables method.

<?php

use Preprio\Prepr;

$apiRequest = new Prepr('{ENDPOINT_URL}');

$apiRequest
    ->rawQuery('query ($search : String) {
                    Posts(where: { _search : $search }) {
                        items {
                            title
                        }
                    }
                }')
    ->variables([
        'search' => "amsterdam",
    ])
    ->request();

print_r($apiRequest->getResponse());

Using query files

If you saved your GraphQL queries to a static file, you can use the following method to execute those:

<?php

use Preprio\Prepr;

$apiRequest = new Prepr('{ENDPOINT_URL}');

$apiRequest
    ->query('query_file.graphql')
    ->request();

print_r($apiRequest->getResponse());

Adding headers

In some cases, you may need to add headers to your request. For example, when using Prepr personalization with the Prepr-Customer-Id header.

The example below shows how to add extra headers to the requests.

<?php

use Preprio\Prepr;

$apiRequest = new Prepr('{ENDPOINT_URL}');

$apiRequest
    ->headers([
        'Prepr-Customer-Id' => 'your-customers-session-or-customer-id'
    ])
    ->request();

print_r($apiRequest->getResponse());

Debug Errors

With $apiRequest->getRawResponse() you can get the raw response from the Prepr API.
