}Authorizations
Mixpeek API key, sent as Authorization: Bearer mxp_sk_.... Create one in Studio under Settings → API Keys, or with an admin key via POST /v1/organizations/users/{user_email}/api-keys. A missing, malformed, unknown, revoked, inactive or expired key returns 401; a key without the permission, scope or plan an operation needs returns 403.
Namespace id (ns_...), not the namespace name. This scopes the request rather than authenticating it, and it is required on every operation marked x-mixpeek-namespace-scoped.
Path Parameters
The unique identifier of the bucket
Query Parameters
Insertion policy for unique key enforcement on the object created at confirmation. Valid values: 'insert', 'update', 'upsert'. Only applies if the bucket has a unique_key. Overrides the bucket's default_policy, matching ?policy= on POST /objects. Required when the bucket has a unique_key and no default_policy.
Available options:
insert, update, upsert Example:
"insert"
Body
application/json
Keys this body does not declare are ignored, and the response's warnings name them, until 2026-11-02; from 2026-11-02 they are refused with 422 extra_forbidden naming the accepted keys.
Request to confirm multiple uploads in batch.
List of confirmations with upload_id, etag, file_size_bytes
Required array length:
1 - 100 elementsResponse
Successful Response
Response from batch confirmation.
Task ID for tracking batch confirmation progress
Task status
Available options:
PENDING, QUEUED, IN_PROGRESS, PROCESSING, COMPLETED, COMPLETED_WITH_ERRORS, FAILED, CANCELED, INTERRUPTED, UNKNOWN, SKIPPED, DRAFT, ACTIVE, ARCHIVED, SUSPENDED, DEACTIVATED Number of confirmations being processed
