# Shopify API
**Currently a Work in Progress**
This package allows Elixir developers to easily access the admin Shopify API.
## Installation
The package can be installed by adding `shopify` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[{:shopify, "~> 0.1.3"}]
end
```
## Getting Started
The Shopify API can be accessed in two ways - either with private apps via basic auth, or with oauth.
### Private Apps
Once you have a valid API key and password, setup your `config/confix.exs`.
```elixir
config :shopify, [
shop_name: "my-shop",
api_key: System.get_env("SHOPIFY_API_KEY"),
password: System.get_env("SHOPIFY_API_PASSWORD")
]
```
We can now easily create a new API session.
```elixir
Shopify.session
```
Alternatively, we can create a one-off session.
```elixir
Shopify.session("my-shop-name", "my-api-key", "my-password")
```
### OAuth Apps
Once you have a shopify app client ID and secret, setup your `config/confix.exs`.
```elixir
config :shopify, [
client_id: System.get_env("SHOPIFY_CLIENT_ID"),
client_secret: System.get_env("SHOPIFY_CLIENT_SECRET")
]
```
To gain access to a shop via OAuth, first, generate a permission url based on your requirments.
```elixir
params = %{scope: "read_orders,read_products", redirect_uri: "http://my-redirect_uri.com/"}
permission_url = Shopify.session("shop-name") |> Shopify.OAuth.permission_url(params)
```
After a shop has authorized access, they will be redirected to your URI above. The redirect will include
a payload that contains a 'code'. We can now generate an access token.
```elixir
{:ok, oauth} = Shopify.session("shop-name") |> Shopify.OAuth.request_token(code)
```
We can now easily create a new OAuth API session.
```elixir
Shopify.session("shop-name", oauth.access_token)
```
## Making Requests
All API requests require a session struct to begin.
```elixir
Shopify.session("shop-name", "access-token") |> Shopify.Product.find(1)
# OR
session = Shopify.session("shop-name", "access-token")
Shopify.Product.find(session, 1)
```
Here are some examples of the various types of requests that can be made.
```elixir
# Create a session struct
session = Shopify.session("shop-name", "access-token")
# Find a resource by ID
{:ok, resource} = session |> Shopify.Product.find(id)
# Find a resource and select fields
{:ok, resource} = session |> Shopify.Product.find(id, %{fields: "id,images,title"})
# All resources
{:ok, resources} = session |> Shopify.Product.all
# All resources with query params
{:ok, resources} = session |> Shopify.Product.all(%{page: 1, limit: 5})
# Find a resource and update it
{:ok, resource} = session |> Shopify.Product.find(id)
updated_resource = %{resource | title: "New Title"}
{:ok, resource} = session |> Shopify.Product.update(updated_resource.id, updated_resource)
# Create a resource
new_product = %Shopify.Product{
title: "Fancy Shirt",
body_html: "<strong>Good shirt!<\/strong>",
vendor: "Fancy Vendor",
product_type: "shirt",
variants: [
%{
price: "10.00",
sku: 123
}]
}
{:ok, resource} = session |> Shopify.Product.create(new_product)
# Count resources
{:ok, count} = session |> Shopify.Product.count
# Count resources with query params
{:ok, count} = session |> Shopify.Product.count(%{vendor: "Fancy Vendor"})
# Search for resources
{:ok, resource} = session |> Shopify.Customer.search(%{query: "country:United States"})
# Delete a resource
{:ok, _} = session |> Shopify.Product.delete(id)
```
Results are all returned in the form of a two-item tuple.
```elixir
# Create a session struct
session = Shopify.session("shop-name", "access-token")
# 'resource' is returned as a %Shopify.Product struct
{:ok, resource} = session |> Shopify.Product.find(id)
# 'resources' is returned as a list of %Shopify.Product structs
{:ok, resources} = session |> Shopify.Product.all
# 'error' is returned as a %Shopify.Error struct
{:error, error} = session |> Shopify.Product.find(1)
```
