How It Works
This source, once deployed, listens to orders.create events from your linked Shopify Store. When a new order is created
we loop through the line items of the order and check if any of them are defined in GIFT_PRODUCT_TO_PRODUCT_MAPPING in helpers.js.
You'd need to define a mapping of the gift products IDs to the IDs of the actual products that will be gifted, you can get your
product ID by logging into your Shopify Store Admin Dashboard and clicking the product, it will be in the URL:
Then add the IDs like so:
// Gift Product ID -> Actual Product ID
const GIFT_PRODUCT_TO_PRODUCT_MAPPING = {
1234567890123: 1122334455667,
5152233445566: 4777112233447
};
After the Gift Products have been identified from the line items of the Order, we loop through them, and
generate a new 12 character alphanumeric code that will be used as the Discount Code:
let generatedDiscountCode = crypto.randomBytes(6).toString("hex").toUpperCase();
We then call the products.retrieve endpoint to fetch
information about the product that will be gifted (mainly the title):
let productId = `gid://shopify/Product/${productIdNumber}`;
// Fetch information about product that will be gifted
let product = await lib.shopify.products['@2020.7.0'].retrieve({
id: `${productId}`
});
Afterwards we create a new one time use 100% off Discount Code for the gifted product with the new code we generated earlier,
using the discountcodebasics.create endpoint:
// Create a new one time use 100% off discount code for that product
await lib.shopify.discountcodebasics['@2020.7.0'].create({
title: `${product.title} Gift Discount Code (${event.customer.email})`,
startsAt: new Date().toISOString(),
endsAt: null,
usageLimit: 1,
appliesOncePerCustomer: true,
customerGets: {
'value': {
percentage: 1.00 // Get 100% off product
},
'items': {
products: {
productsToAdd: [`${productId}`]
}
}
},
customerSelection: {
'all': true
},
code: generatedDiscountCode
});
And finally once the Discount Code is created, we send it in an email to the customer, using Gmail's messages.create
let customerEmail = event.customer.email || event.email;
// Send email to customer containing the purchased gift Discount Code
await lib.gmail.messages['@0.2.0'].create({
to: `${customerEmail}`,
subject: `Your Gift Product Discount Code`,
html: ejs.render(emailTemplate, {
product: product,
customer: event.customer,
generatedDiscountCode: generatedDiscountCode
})
});
A default email template is used from templates/template.html, utilizing ejs to render and
handle passing in variables. You can upload your own template to ./templates and use it instead, make sure you
change line 14 to include your template:
let templateFilename = './templates/your_template.html';
