Explicitly dispatch an existing native material preparation
Generated from the checked-in source. Do not edit this reference by hand.
POST /v1/media/operations/{id}/dispatch
Current selected key, exact model/account/channel and workspace Write authority required. Safe Niu references only; no Provider identifiers, source URLs, credentials or procurement prices returned. Requires an already saved operation matching the original idempotency UUID and full canonical input. Never creates a missing preparation. Atomic prepared-to-unknown claim precedes a single Provider call; unknown and terminal records never redispatch. No automatic retries.
Operation: dispatchProviderAssetOperation.
Authentication
Section titled “Authentication”Use the credential and permission scope described above. Each object below is an alternative; schemes within one object are required together.
[ { "bearerAuth": [] }, { "niuApiKeyAuth": [] }]HTTP request
Section titled “HTTP request”Set NIU_ORIGIN to your installation origin (without /v1). Replace path, query and header placeholders with the required values. Query examples use curl 7.87 or newer to encode values with --url-query. Use the credential scope described above; a bearer token must have the authority required by this operation.
Authentication alternative: bearerAuth.
