What's changing?
We've introduced new fields to provide an identifier for each order item, such as an IMEI (for smartphones, tablets, and smartwatches) or a serial number (for other product categories). You can find these in the new item_identifiers array for all order item update methods. One identifier of each type can be added per order item.
"item_identifiers": [
{
"identifier_type": "UNSPECIFIED",
"value": "string"
}
]
This replaces the old item_identifier field and lets you specify the identifier type (IMEI or SERIAL_NUMBER). IMEIs have to be 14-16 digits and numeric.
The old item_identifier field will be deprecated and removed in early June 2026.
Why this change?
This update ensures compliance, transparency, and smooth operations.
