Develop a simpel Shopify integration

The task is to develop and setup a simple integration to Shopify where customers can click a button (Get it today) and send the contents of the current basket to our API, and then forward the user to the `checkoutUrl` returned. ​ The button can be located in the header, and doesn't have to be on the basket page, but both are valid options. ​ Sending Requests ============================= All requests should be sent to `[login to view URL]`. To authorize your reqeusts you should include an authorization key. This can be done by setting a header "Basic [base64 encoded auth key]", or by setting a --user key in a curl request. ​ Flow ------------------- First you create a delivery, with the corresponding api rute, afterwards you'd forward the user to the returned `checkoutUrl`, where we will handle the checkout itself. Here the user can provide delivery location as well as payment for the service itself. ​ Create a delivery (POST /api/v1/delivery) ================================================= To create a delivery, you create a delivery request, which gives you the option to create multiple deliveries at the same time, in case there are multiple pickup locations, thus we'd need multiple shoppers to pickup one for each location. ​ Most arguments are optional, but the more information can be provided the better for the shoppers, and thus the customer. ​ The format of the body sent to us should look like the following example. Everything denoted with an exclamation mark (!) are required fields, everything else is optional. ​ The request will return an object with a list of created deliveries as well as a `checkoutUrl`. ​ Structure of body: ------------------- ``` { deliveryLocation: Address deliveries: [{ pickup: { brandName: String! location: Address }! items: [{ name: String! quantity: Number! group: String # A name to group together different items (ie. fruit, cheese, etc..) imageUrl: String # Url to fetch the image of the item from description: String # description of the item if needed ​ # This should be defined only if there's an offer on the item offerPrice: { currencyCode: DKK | USD | SEK | NOK (etc...) REQUIRED amount: Integer! # In lowest currency value (cents in USD, øre in DKK, etc...) validFrom: Date # should be formatted as ISO string, or milliseconds since EPOC validTo: Date # should be formatted as ISO string, or milliseconds since EPOC quantityLimit: Number # If there's a limit to how many you can purchase with this offer } ​ price: { currencyCode: DKK | USD | SEK | NOK (etc...) REQUIRED amount: Integer! # In lowest currency value (cents in USD, øre in DKK, etc...) } }]! }] } ``` ​ Address definition: ------------------- ``` { co: String # Name of the customer address1: String! address2: String zipCode: String! city: String! state: String country: String! (Two letter contry code, DK, UK, US, etc..) } ``` ​ ​ Example ------------------- curl [login to view URL] \ -u sk_someauthkey: \ -H "Content-Type: application/json" \ -d '{"pickup":{"brandName":"Netto"}, "items":[{"name":"Apple","quantity":2}]}' ``` { "deliveries": [{ "id": "delv_fdGFvYcDtyzvLNt5Pa4cSp", }], "checkoutUrl": "[login to view URL]", } ``` ​ ​ GET /api/v1/delivery/[id] ============================= ​ Example ------------------- curl [login to view URL] \ -u sk_someauthkey: ​ ``` { ​ "delivery": { "id": "delv_fdGFvYcDtyzvLNt5Pa4cSp", }, "checkoutUrl": "[login to view URL]", } ```
