I'm using a Run Code action to calculate the credit to be applied. My application also applies a different percentage of the order to be credited based on what tier the customer is (3% - default, 4.5%, or 6% based on certain customer tags if present):
Input:
query {
order {
customer {
tags
}
subtotalPriceSet {
shopMoney {
amount
}
}
}
}
Output:
"Output object"
type Output {
"Calculated Store Credit"
storeCredit: Float!
}
Code:
/**
* Calculate the store credit to be applied on purcahse
*/
export default function main({order}) {
const subtotal = order.subtotalPriceSet.shopMoney.amount;
var reward = 0.03;
if(order.customer.tags.includes('elite-member')){
reward = 0.045;
} else if(order.customer.tags.includes('vip-member')){
reward = 0.06;
}
return { storeCredit: (subtotal * reward).toFixed(2)};
}
Then I use the Send API request to send the storeCreditAccountCredit mutation to the GraphQL Admin API:
{
"id": "{{order.customer.id}}",
"creditInput": {
"creditAmount": {
"amount": "{{runCode.storeCredit}}",
"currencyCode": "{{order.currentTotalPriceSet.presentmentMoney.currencyCode}}"
},
"expiresAt": "{{order.createdAt | date: "%s" | plus: 31536000 | date: "%Y-%m-%dT%H:%M:%S%z"}}"
}
}
The real thing that took a some trial and error was, from that I could see, the expiresAt field appears to be required. I tried excluding it and setting that to false since I wanted my credits to not have an expiry date but none of those options seemed to work. So instead, I'm using a date that is 365 days after the order creation which should work. If anyone can suggest why I wasn't able to create a credit without an expiry date, I'd welcome the input.
I'm still testing things to make sure all my conditions work as expected but so far, things appear to be working well.
