# Acknowledge a prepared source write

`POST /v1/spaces/{spaceId}/content/sync/acknowledge`

## Request

- Base URL: `https://api.spacefast.com`
- URL: `https://api.spacefast.com/v1/spaces/{spaceId}/content/sync/acknowledge`
- Auth: one of:
  - HTTP bearer
  - OAuth 2 (authorization code, authorization URL `https://api.spacefast.com/v1/auth/oauth2/authorize`, token URL `https://api.spacefast.com/v1/auth/oauth2/token`; client credentials, token URL `https://api.spacefast.com/v1/auth/oauth2/token`, scopes: `spaces:write`)

Closes a reconciliation that prepared a source write, once the caller has landed those bytes. Refused when the ledger moved on, so a file nobody reconciled is never adopted as the common base.
