How to request shopify graphql-admin-api from an api?

Question

I am trying to request shopify graphql-admin-api from my api. I am doing it according to the documentation given by graphql-admin-api, but it still gives me authorization errors.

Answer 1

PHP users can follow this function to make request to Shopify Admin API using GraphQL

I am using GuzzleHttp ( PHP HTTP client ) to create request

public function graph($query , $variables = []){
    $domain = 'xxx.myshopify.com';
    $url = 'https://'.$domain.'/admin/api/2019-10/graphql.json';

    $request = ['query' => $query];

    if(count($variables) > 0) { $request['variables'] = $variables; }

    $req = json_encode($request);
    $parameters['body'] = $req;

    $stack = HandlerStack::create();
    $client = new \GuzzleHttp\Client([
        'handler'  => $stack,
        'headers'  => [
            'Accept'       => 'application/json',
            'Content-Type' => 'application/json',
            'X-Shopify-Access-Token'=>$this->token // shopify app accessToken
        ],
    ]);

    $response = $client->request('post',$url,$parameters);
    return $body =  json_decode($response->getBody(),true);
 }

  $query = "{ shop { name email } }"; // this is example graphQL query

  $response = graph($query) // call this function 

Below code can help you to check how much cost this graphQL query

$calls = $response->extensions->cost;
$apiCallLimitGraph = [
     'left'          => (int) $calls->throttleStatus->currentlyAvailable,
     'made'          => (int) ($calls->throttleStatus->maximumAvailable - $calls->throttleStatus->currentlyAvailable),
     'limit'         => (int) $calls->throttleStatus->maximumAvailable,
     'restoreRate'   => (int) $calls->throttleStatus->restoreRate,
     'requestedCost' => (int) $calls->requestedQueryCost,
     'actualCost'    => (int) $calls->actualQueryCost,
];

Go to Apps -> Manage Apps at the bottom and then : Create a private app in Shopify, which will connect to your application. Make sure you manage permission for what you want to query

After creating the private app you will get the password which you can use as the token for your HTTP requests with header 'X-Shopify-Access-Token' value: password

  curl -X POST \
  https://{shop}.myshopify.com/admin/api/2021-04/graphql.json \
  -H 'Content-Type: application/graphql' \
  -H 'X-Shopify-Access-Token: {password}' \
  -d '
  {
    products(first: 5) {
      edges {
        node {
          id
          handle
        }
      }
      pageInfo {
        hasNextPage
      }
    }
  }
  '

The way I use in NodeJS is by using package "graphql-request" to make requests and

const mutation = gql`
      mutation createProduct(
        $input: ProductInput!
        $media: [CreateMediaInput!]
      ) {
        productCreate(input: $input, media: $media) {
          userErrors {
            field
            message
          }
          product {
            id
            metafields(first: 1) {
              edges {
                node {
                  id
                }
              }
            }
          }
        }
      }
    `;
     //const input = form your own input 
     const res = await graphQLClient.rawRequest(mutation, input);
