Complete upload — Brigg developers

Access & visibility

Allow documents.CompleteUpload 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.

upload_idstringRequired

Keep the upload_id and the same credential and acting member throughout the upload. Completion returns a separate file_id. documents.CreateUpload.

At least 1 character.

partsarray of objectOptional

Optional receipts for uploaded parts. Completion can retrieve receipts when this list is omitted.

Item fields

part_numberintegerRequired

One-based part number. Use 1 for a single upload; for multipart uploads, transfer every part from 1 through part_count.

Greater than 0.

etagstringRequired

Optional explicit multipart receipt. When supplying parts, preserve the complete ETag value including quotes. Otherwise omit the parts array and Brigg collects the receipts automatically.

At least 1 character.

Where this fits in an upload

The file guide includes a streaming Node.js helper and the complete HTTP sequence: create an upload, request a signed URL for each part, PUT the bytes directly to that URL, then complete the upload. Never send the Brigg API key to a transfer URL.

Keep the same credential and acting member for every step. Follow the returned part size and count rather than imposing your own split. Completing with only upload_id lets Brigg collect part receipts. A successful byte transfer is not a completed file: verification and scanning must finish before you receive a usable file_id.

Retain upload_id for recovery. Read its state before retransferring an interrupted upload; ready returns the existing file ID, while an expired upload requires a new start. Temporary transfer URLs and completed file IDs have different lifetimes.

Response

Returns 200 OK with a JSON body.

file_idstringRequired

Stable file ID returned by documents.CompleteUpload, documents.ListDocuments or a document creation operation. Use the same ID for downloads, attachments and supported file-based workflows. Do not use a filename or storage path.

filenamestringRequired

Original filename, including its extension.

content_typestring or nullRequired

Media type of the file, such as application/pdf. Null when no binary file exists.

size_bytesnumber or nullRequired

File size in bytes. Null for a document without a downloadable binary file.

visibilitystringRequired

Who may read the completed file. Personal files belong to the approved acting member; workspace files use shared access.

Allowed: "personal", "workspace".

scan_statusstring or nullRequired

Malware scan state. Threats and failed scans block downloads. An unsupported file cannot be processed; only its original uploader can retrieve it as a forced download. Null is not proof of readiness.

Errors & retries

Set BRIGG_REQUEST_ID once for each logical action. The samples send it as Idempotency-Key. Reuse the same value and body on retries, including after a timeout; a missing response does not prove the action failed.

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. Supply a stable Idempotency-Key containing 1–200 characters.
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.
404	`not_found`	The requested operation or resource is not available to this credential.
429	`rate_limited`	Wait for Retry-After before retrying. Reuse the original Idempotency-Key.
409	`upload_incomplete`	Transfer all parts with their exact planned byte lengths before completing the upload.
409	`file_scan_pending`	Wait Retry-After seconds, then retry with the same input and idempotency key.
409	`file_scan_blocked`	The file cannot be used because its malware scan was blocked.
409	`upload_closed`	This upload was cancelled or is no longer open.
410	`upload_expired`	Start a new upload with a new idempotency key.
