Refreshes the temporary upload instruction for a pending session. File properties and the one-hour session deadline remain unchanged. No replacement file or metadata is accepted.

Parameters

upload_idstring

ID of the media-library upload session.

Response Payload

id
string
verplicht
state
string
verplicht

The session is awaiting transfer and completion.

Value: pending

expires_at
string
verplicht

Absolute session expiry. Completion must finish before this deadline; starting it or refreshing an upload instruction does not extend it.

name
string
verplicht

Frozen display name for a newly published asset.

alt_text
nullable string
verplicht

Frozen alternative text, or null when omitted.

folder_id
nullable string
verplicht

Frozen destination folder, or null for the library root.

file
object
verplicht

Exact properties of the original file. Calculate size and SHA-256 from its bytes before creating a session. Images allow up to 5,242,880 bytes; other supported media allow up to 25,000,000 bytes.

next.kind
string
verplicht

What you do about this step.

  • operation: call the operation named in operation, then read again.
  • external: act somewhere this API does not reach, then read again.
  • wait: nothing is asked of you, so read again later.
  • terminal: nothing you do resolves this, so stop retrying.

Tolerate a value you do not recognize: show the description and offer no action.

Possible values (may grow over time): operation, external, wait, terminal

next.description
string
verplicht

A short, human-readable label for the step, suitable for display.

next.operation
string

The operationId to call. Present only when kind is operation. The operation's own schema says how to call it; this says only which one, and what to address it with.

next.params
object

The parameters that address the operation, by name: {"sender_id": "…"} for an operation on /v1/sms/senders/{sender_id}/requirements. A parameter the operation takes in its query string is given the same way, so an operation addressed as ?subject_id= carries {"subject_id": "…"}. Every parameter the call needs is here, whether its value came from the thing you were acting on or is fixed for this step, so you can make the call from this object alone. Present only when kind is operation and the operation names a subject. A request body, when the operation takes one, is described by the operation's own schema and never appears here.

next.url
string

A URL to open. Present only when kind is external, and only when the step has one. An external step whose description says to go and do something with no URL to open is normal.

upload
object
verplicht

Send the original file bytes to this URL with the exact headers and content length. Send no Bird credentials or cookies. Keep the URL private and call complete after the PUT succeeds.
