I am currently using sandeepshetty's shopify.php plugin on github https://github.com/sandeepshetty/shopify.php
The plugin appears to work and the logic is fairly simple. I have tested it using the "Create a new Fulfillment", however I get an error message when using the "Modify an existing Fulfillment" API call.
I submit the following string and I receive a 404 error
$orders = $shopify('PUT', "/admin/orders/160387514/fulfillments/791851111396.json", $fulfillment_put, $response_headers);
Where $fulfillment_put translates to the payload
{ "fulfillment": { "tracking_number": "987654321", "id": 255858046 } }
The following is a verbose dump from the PUT command. As can be seen above, I used the following format for the path. I did replace a few variables with either hidden or alt just as an fyi.
/admin/orders/#{order_id}/fulfillments/#{product_id}.json

P.S. I would like to note that I used the following API documentation http://docs.shopify.com/api/fulfillment#create
It suggests that I use PUT /admin/orders/#{id}/fulfillments/#{id}.json
However, #{id} is referenced in there twice, suggesting that I should use the Order ID twice in a row, but the documentation clearly shows the example of /admin/orders/450789469/fulfillments/255858046.json I would like more clarification on what the actual #{id}'s stand for and how to use them.
I think you're just using the wrong ID for the second one in /admin/orders/#{id}/fulfillments/#{id}.json. You're right about the first one, it's the order ID, but the second one is the fulfillment ID. The fulfillment ID was returned in the create fulfillment response.
