Get signing document — Brigg developers

Access & visibility

Allow signing.GetSigningDocument on your API key.

Workspace access by default. Private member data requires approved member delegation through Brigg-Act-As; the key supplies permissions while private ownership and project boundaries remain enforced.

Request fields

Send a JSON object with the following fields. Required fields must be included; omit optional fields you do not need.

signing_request_idstringRequired

Keep the signing_request_id returned when invitations were requested. A file_id or signer_id identifies something else. signing.RequestFileSignatures.

At least 1 character.

versionstringOptional

Which document to download: the original source or the completed signed archive.

Allowed: "original", "signed". Default: "signed".

Follow one signing request through completion

Upload a readable PDF, then request signatures and keep signing_request_id. The request keeps a fixed source; replacing the original file later does not change what recipients sign.

Read Get signing request for per-recipient progress. completed means everyone signed, but the archive can still be preparing: wait for non-null file_id before requesting the signed PDF. Get signing document returns a short-lived URL for either the fixed original or the signed archive.

Notification failures do not undo the signing request. Remind the affected pending recipients instead of creating a duplicate request. Recipients sign themselves; a delegated API call cannot supply a recipient's signature. See the complete signing workflow.

Response

Returns 200 OK with a JSON body.

urlstringRequired

Absolute URL, including its scheme.

filenamestringRequired

Original filename, including its extension.

expires_atnumberRequired

Signing deadline in Unix milliseconds.

Errors & retries

This operation reads data. It needs no idempotency key and can be retried after a transient failure.

For rate limits, follow the server’s retry guidance and back off. See HTTP errors and safe retries and limits.

HTTP status	Code	What to do
400	`invalid_json`	Send a JSON object with Content-Type: application/json.
400	`invalid_input`	Check the request fields and types.
401	`invalid_key`	The workspace API key is missing, invalid or revoked.
403	`forbidden`	Check the key’s operation and resource grants. If Brigg-Act-As is supplied, the key must be authorized to delegate to that member.
