Set Shipping Method Carrier
PUT/api/walmart/:integrationInstance/routing/methods/:shippingMethod
Sets the Walmart carrier for a single shipping method (layer 1) — the highest-priority layer.
This endpoint currently requires session authentication; Personal Access Token scope support is in progress.
Send walmart_carrier: null with suppress: false to clear it, which drops the method back to its carrier family's default. Set suppress: true for a method that is not a carrier shipment.
Every change returns the COMPLETE refreshed routing configuration, not just the row that changed — the layers interact, so a partial response could disagree with what the next shipment would actually send.

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.
Validation failed — the body is a field → messages map (Laravel shape) or the platform envelope with a stable machine-readable code. Fix the payload and resubmit.
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.
