Change Promotion End Date
POST/api/walmart/:integrationInstance/promotions/extend
Move the end date of existing promotions, in or out.
integrations:writeGrant this scope to your token under Settings → Developer → Personal Access Tokens.
Each promotion is re-submitted at its OWN price and start date with the new end date — the price is not re-derived from a discount rule, so extending a promotion cannot quietly re-price it against a catalogue that has moved since it started.
Submits one promotion feed for the whole selection. The new end date must fall after every selected promotion's start date.
Authentication: Requires Bearer token.
Requires the integrations.sync permission.

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.
