The request body must be a JSON object where each key is a line item identifier (as a String) and each value is a list of AttributeInfo objects containing attribute key/value pairs. For example: { "gid://shopify/SubscriptionLineItem/987654321": [ { "key": "color", "value": "red" }, { "key": "size", "value": "M" } ] }. The service validates that the contract exists and that each specified line item is eligible for update. Authentication is performed via the X-API-Key header (the 'api_key' parameter is deprecated). ## OpenAPI ````yaml /subscription/admin-api-swagger.json put /api/external/v2/subscription-contracts-update-multiple-line-item-attributes openapi: 3.0.1 info: description: >- Comprehensive API documentation for managing subscriptions, payments, and related operations.
