Refund Walmart Return
POST/api/walmart/:integrationInstance/returns/:return/refund
Issue a refund against a Walmart Marketplace return order. Without a request body, every returned line is refunded at its full quantity. To refund only specific line(s) or quantities, send an optional lines array — each item has returnOrderLineNumber (integer, required) and quantity (integer ≥ 1, required). Reflects the refund status locally.
Any valid API token can call this endpoint — no specific scope required. Manage tokens.
WFS-fulfilled returns are settled by Walmart and cannot be refunded here; attempting to refund one (or any Walmart-side failure) returns a 422 with the failure reason. The return must belong to the integration instance in the path (404 otherwise).
Requires a Bearer token.

Response Headers
Unauthenticated — the bearer token is missing, revoked, expired, or malformed. Never retry automatically; fix the credential. See the Errors guide.
Forbidden — the token lacks a required scope, the endpoint is not available to API tokens, or the user behind the token lacks the permission. A human must adjust the token scopes or user permissions; do not retry.
Not found — no record with the given identifier (or the route does not exist). Verify the ID before retrying.
Unprocessable Entity
Response Headers
Rate limited — platform limit is 1,000 requests/min; individual tokens may carry lower limits. Honor the Retry-After header before retrying. See the Rate Limits guide.
