Shopify just announced that starting with REST Admin API version 2027‑01, the line_item_id property on the Gift Card resource will be read‑only. If your app creates or updates gift cards via the REST API and includes this field, the value will be ignored and the original association will stay unchanged. This post breaks down the change, who it affects, and the exact actions you need to take to keep your integration running smoothly.
What Changed
In API version 2027‑01 and later, the line_item_id field can no longer be added, replaced, or cleared through Gift Card create or update requests. Shopify will silently drop any line_item_id value sent in the payload, preserving the existing association with the order line item that originally created the gift card. The field remains present in GET responses, so you can still read the current association.
Who Is Affected
Why This Matters
The line_item_id records the specific order line item that generated the gift card. Making it read‑only protects data integrity by preventing external apps from altering that linkage, which could cause accounting, fulfillment, or reporting discrepancies.
Breaking Changes & Migration Steps
Code Example: Removing line_item_id
// Before – problematic payload (API <2027‑01)
const payload = {
gift_card: {
amount: "50.00",
currency: "USD",
line_item_id: 1234567890 // ❌ will be ignored in 2027‑01+
}
};
// After – compliant payload (API >=2027‑01)
const payload = {
gift_card: {
amount: "50.00",
currency: "USD"
// line_item_id removed
}
};
// POST /admin/api/2027-01/gift_cards.json
fetch('/admin/api/2027-01/gift_cards.json', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(payload)
});
Testing the Migration
After sending a create or update request without line_item_id, fetch the same gift card (GET /admin/api/2027-01/gift_cards/{id}.json). Verify that the line_item_id field still shows the original value and that no error was returned. This confirms that Shopify ignored the field as expected and your app’s state matches the platform.
Conclusion & Next Steps
The read‑only shift for line_item_id is a small but important change that safeguards the relationship between gift cards and their source orders. By stripping the field from your create/update payloads now, you avoid silent data mismatches when you upgrade to API version 2027‑01. Keep monitoring Shopify’s changelog for future API adjustments, and consider adding a linting rule in your codebase to flag any usage of line_item_id in write operations.
