File Uploads & Downloads

Attach files to entries and retrieve existing files through your AI assistant.

The AI can upload files to Inistate entries and retrieve download links for existing files. Both operations work in all three modes.

Uploading a File

The AI uses a three-step presigned upload flow that supports files up to 500 MB.

1

Request an upload URL

The AI calls request_upload_url with the file name, MIME type, and size. Inistate returns a pre-signed S3 URL valid for approximately 1 hour.

2

Upload the file to S3

The AI sends the file bytes directly to the S3 URL. The Content-Type header must match exactly.

3

Confirm the upload

The AI calls confirm_upload with the s3Key returned in step 1. Inistate verifies the file is in S3 and returns the file path used in entry field values.

After confirmation, the AI attaches the file to the entry by including the path in a submit_activity call.

Example prompts

"Attach this PDF to invoice INV-1042."

"Upload the signed contract to PO-0234."

"Add a photo to this equipment inspection entry."

What the AI does

Supported file types include documents, images, spreadsheets, and most common formats. Executable files (.exe, .bat, .cmd, .dll, .msi) are blocked.

Downloading a File

To retrieve an existing file from an entry, the AI requests a pre-signed download URL that expires after 1 hour.

Example prompts

"Download the attachment from invoice INV-1042."

"Get the signed contract from PO-0234."

"Show me the photo attached to inspection entry INS-0012."

What the AI does

Download links expire after 1 hour. If you need to share a file, do so promptly after requesting the link.
