Revert Cost Change
POST/api/cost-changes/:costChange/revert
Returns an applied or dismissed cost change to the inbox. For an applied change, every revaluation it produced is reversed, anything re-costed downstream is unwound, and the set is re-staged for review with a fresh preview; posted ledger entries are reversed and drafts discarded. For a dismissed change the set is simply reopened.
inventory:writeGrant this scope to your token under Settings → Developer → Personal Access Tokens.
Responds 409 when the change is already in the inbox, when it was applied by a backfill (switch its resolution instead), or when the same inventory has been revalued by a later change that must be reverted first. Use Get Decision Impact with to=revert to see the ledger and provider consequences before calling this.
Authentication: Requires Bearer token (inventory scope) and permission to resolve cost changes.
Path params:
- costChange: Cost change set ID
Body fields:
- notes (optional, max 2000 chars): recorded on the decision

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.

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.
