post/v1/tasks/{taskId}/attachments

Request

  • Base URL
    https://api.trycomp.ai
  • Auth
    API key in header X-API-Key

Path parameters

taskIdstring required
Example:tsk_abc123def456

Unique task identifier

Request body

fileNamestring required

Name of the file

fileTypestring required

MIME type of the file

fileDatastring

Base64-encoded file contents. For the web UI / direct callers. AI/MCP clients should instead upload via /v1/uploads/presign (purpose=attachment) and pass s3Key — base64 through an LLM is impractically slow and times out. Provide exactly one of fileData or s3Key.

s3Keystring

Key of a file already uploaded via /v1/uploads/presign (purpose=attachment). The server fetches the bytes from storage — no base64 needed. Provide exactly one of fileData or s3Key.

descriptionstring

Description of the attachment

userIdstring

User ID of the user uploading the attachment (required for API key auth, ignored for JWT auth)

Example request

{
  "fileName": "document.pdf",
  "fileType": "application/pdf",

  "s3Key": "org_abc123/uploads/attachment/1700000000000-rbac-matrix.xlsx",
