Attach a CHAT file to a deal: the write twin of listDealFiles.

Attach a CHAT file to a deal: the write twin of listDealFiles. Pass the artifactId of a file your organization already holds: the id the chat assistant sees on its artifact shelf ((artifactId: …) [origin] filename). A Library item id is refused: use fileLibraryItemsOnDeal. The server resolves it to the underlying file, org-scoped, links it to dealId, and returns the file (id, fileName, fileUrl, createdAt); read it back with listDealFiles. The deal must be in a pipeline owned by or shared with your organization, and the artifact's file must belong to your organization: a foreign artifact is refused, so you cannot link another org's bytes onto a deal you own. There is no raw-bytes upload op yet (the shared upload key is not org-scoped).

Variables

The example sends only what the schema requires. Some operations also need one of several optional variables (one filter or another, say); the description above says which.

dealIdID!required
artifactIdID!required

Response

What comes back under data: a list shows as one entry, and a value as its type.

response shape

  "data": {
    "dealMutation": {
      "attachDealFileFromArtifact": {
        "id": "<ID>",

    }
  }
}

Errors

400unknown_variable

A variable the operation does not declare. A typo is refused rather than silently dropped.

401unauthorized

No bearer header, or the key is invalid or revoked.

403insufficient_scope

The key lacks the scope the operation requires.

403forbidden

A referenced record does not exist, was deleted, or is outside your organization. The gateway cannot tell those apart.

409idempotency_conflict

A request with this Idempotency-Key is still in flight.

Idempotency

Send an Idempotency-Key of 1 to 255 characters. A finished request retried with the same key replays its stored response, marked Idempotency-Replayed: true; one still in flight returns 409 idempotency_conflict. Keys expire after 24 hours. Write without fear →
