POST/v1/cards

Upload a file as a card

upload_card

Send the document in the file field of a multipart/form-data form. Before saving, Sursa checks that the file name extension, the declared Content-Type of the part and the content signature agree:
- PDF;
- DOCX, XLSX, XLSM, PPTX: a ZIP with the declared main document type;
- ODS: a ZIP with a mimetype entry;
- XLS: an OLE2 document with a workbook stream;
- TXT, MD, CSV, TSV, HTML, AsciiDoc, EML: text without null bytes in UTF-8 or a single-byte encoding, and for email, headers at the start;
- PNG, JPEG, TIFF, WebP, BMP: by signature.

A mismatch returns 415 files.type_mismatch; an extension outside the list of formats returns 415 cards.unsupported_format. A file larger than the installation's upload limit or the organization's total storage under its plan returns 413 files.too_large. When antivirus scanning is enabled, an infected file returns 422 files.infected, and if the scanner is unavailable under the “reject” policy, the request returns 503 files.scan_unavailable. Each rejection is written to the audit log as file.rejected.

Instead of the form, you can send an application/json body (CardUploadFromUpload, since 1.62.0): the file is a ready multipart upload upload_id (POST /v1/uploads with the card_file purpose), the fields are the same as in the form, and tags is a list of strings. The file of the upload was already checked at complete (format, antivirus), and the size limit is the multipart upload limit instead of the single-request upload limit. The upload is used once, in the same transaction that creates the card: an upload already used returns 409 uploads.already_used, one that is not ready yet returns 409 uploads.not_ready, a rejected one returns 422 uploads.rejected, one with another purpose returns 422 uploads.purpose_mismatch, an expired one returns 410 uploads.expired, and another caller's or an unknown upload returns 404 uploads.not_found. If the card checks fail (collection, category, limits), the upload is not used up.

Authentication

Send an API key in the Authorization header: Authorization: Bearer <key>.

Header parameters

Idempotency-Keystring
Key for a safe retry of a write: 1 to 255 printable ASCII characters; a UUID v4 per logical operation is recommended. A retry with the same key within 24 hours does not run the operation again: it returns the saved response (status, headers and body) with the Idempotency-Replayed: true header. The same key with a different method, path, Content-Type or body returns 409 api.idempotency_mismatch; while the first request is still running, 409 api.idempotency_in_progress with Retry-After: 1. After a 5xx or 429 response the key is released, and a retry runs the operation again. The key is scoped to the organization and the caller (API key, user, or custom source key).
length ≥ 1, length ≤ 255
X-View-Asstring
For API keys with the admin role only. Makes the request as the data profile <profile>[:viewer|verifier|editor], for example employee:viewer. The installation key cannot use this header (403).

Cookie parameters

kb_view_asstring
Cookie of the “View as” mode for a session. POST /auth/view-as sets it and DELETE /auth/view-as clears it.

sensitiveboolean | null

Default: false
folder_idstring | null
Folder of the collection to put the new card in. A folder of another collection returns 400 folders.card_collection_mismatch, a missing folder returns 404 folders.not_found, and no COLLECTION_EDIT_CARDS permission on the folder returns 403 authz.forbidden. The check runs before the file is saved. A duplicate of a file that is already uploaded (skipped) is not moved into the folder.
length ≤ 64
collection_idinteger | null
Collection by ID. When collection is passed too, collection_id wins. A collection that does not exist in the organization or is not visible returns 404 collections.not_found.
external_idstring | null
external_id of the new card. With it, the card is created even if the collection already has the same file. If another card of the organization uses it, the request returns 409 cards.external_id_taken. To create or replace a card by external_id, use PUT /v1/cards-by-external-id/{external_id}.
length ≤ 512
metadatastring | null
metadata of the new card: a JSON object as the value of the form field. The rules are those of MetadataPatch.

upload_idstringrequired
A ready upload (ready) with the card_file purpose; it is used once.
collectionstring
Default: "default"

external_idstring | null
external_id of the new card, as in the form field. With it, the card is created even if the collection already has the same file. If another card of the organization uses it, the request returns 409 cards.external_id_taken.

Idempotency-Replayed
true means the response was replayed from the saved one for this Idempotency-Key: the operation did not run again.

Error codes

Codes this endpoint can return in error.code, besides the general codes of every request.

Safe retries

Send an Idempotency-Key header (for example a UUID) with each POST and PATCH. A retry with the same key within 24 hours returns the saved response instead of running the request again.

Rate limits

Responses carry the RateLimit and RateLimit-Policy headers and the earlier X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset. A 429 response has Retry-After in seconds: wait and retry.
