**Available on:** [![Meta](/providers/meta.svg)](https://docs.adcrunch.dev/connect/providers) [![TikTok](/providers/tiktok.svg)](https://docs.adcrunch.dev/connect/providers)

Places an Asset in one **advertiser's** provider-side library. Not a provider — an organization has several advertisers, and the bytes land in exactly one of them.

Returns immediately with a `running` Registration; poll `GET /assets/{id}` for its state. Video can take several minutes to process at the provider, which is normal rather than a failure.

A Registration that is `running` or `ready` refuses a second one for the same pair. A `failed` one starts again: send this request, and AdCrunch replaces it.
