Finalize an upload (HEAD-verify the bytes)
const url = 'https://api.aerandil.com/v1/attachments/2489E9AD-2EE2-8E00-8EC9-32D5F69181C0/finalize';const options = {method: 'POST', headers: {Authorization: 'Bearer <token>'}};
try { const response = await fetch(url, options); const data = await response.json(); console.log(data);} catch (error) { console.error(error);}curl --request POST \ --url https://api.aerandil.com/v1/attachments/2489E9AD-2EE2-8E00-8EC9-32D5F69181C0/finalize \ --header 'Authorization: Bearer <token>'Confirm a pending attachment: the server issues a HEAD against the uploaded object and reconciles the actual byte_size / checksum / content_type / etag against the declared intent, then flips the stored_object to available. This is where object storage becomes the source of truth — the row’s available facts are the ones the bytes actually have, not the ones the client claimed.
Scope: objects:write.
Requires AERANDIL_OBJECT_STORE_ENABLED — 501 otherwise.
Authorizations
Section titled “Authorizations”Parameters
Section titled “Parameters”Path Parameters
Section titled “Path Parameters”Object id (UUID v7, server-generated at create time).
Responses
Section titled “Responses”Attachment finalized. The body is the stored_object resource carrying the HEAD-verified available facts.
The finalized stored_object — status available, with the byte_size / checksum / content_type / etag the HEAD verified.

{}Headers
Section titled “Headers”Always no-store — live data is never cacheable.
Quoted strong validator (RFC 7232 §2.3) carrying the object’s monotonic version. Informational on the read path — object mutation goes through typed actions on /v1/actions/{action}/apply, not raw CRUD.
Missing the objects:write scope.
Structured error wrapper. Every non-2xx response from any Aerandil endpoint serialises to this shape; the HTTP status carries the failure class (4xx/5xx), the body adds a stable code for programmatic dispatch plus a human-readable message.
object
object
Stable, programmatic error code (e.g. unauthorized, forbidden, not_found, invalid_body, invalid_url, precondition_failed, no_secondary_key). Clients dispatch on code, not on the message (which may be localised or contextualised in future versions).
Request-id correlation handle echoed on the request-id response header — support teams correlate without scraping logs.
Human-readable explanation of the failure.
Per-error structured detail. The shape varies by code (e.g. forbidden_action carries {"action": "..."}; precondition_failed carries {"current_version": N}).
