We're using https://github.com/phpclassic/php-shopify as our framework to communicate with the shop
and we're getting the orders all fine. Just when wanting to switch the fulfillment_status to "fulfilled" by using this code
$shopify = new PHPShopify\ShopifySDK($config);
$updateInfo = array (
"fulfillment_status" => "fulfilled",
$orderID = '3067744911535';
it doesn't change the status of Order ID 3067744911535 and no error return message.
This next try doesn't work either, but it returns an error
"errors": "An error occurred, please try again"
2878406688943 is the fulfillment id, that we're getting from /admin/api/2020-10/orders/3067744911535/fulfillments.json
Another attempt was
with this content
This does not return an error but also doesn't change the fulfillment_status.
Any chance someone can help us?
