File upload methods
Peak supports multiple ways to upload files for ingestion. Use the method that matches your automation and security requirements.
What are signed URLs?
Peak uses signed URLs to securely upload files to your tenant. A signed URL contains time-limited authentication details in the query string and allows upload without sending credentials in the upload request.
Before you start
Before using signed URL uploads, ensure you have a tenant API key. Peak uses this key to authenticate requests that generate signed URLs.
Supported file types and formatting
Peak expects files to follow supported formats and naming conventions. For requirements, see File formats and naming conventions.
Upload methods
| Method | Typical use case | Requirements |
|---|---|---|
| Ad hoc upload | Manual upload during onboarding or testing | File format compliance and naming rules |
| Signed URL (Postman) | Manual upload using Postman | Tenant API key |
| Signed URL (Python) | Automated upload via script | Tenant API key and Python 3 |
| Signed URL (CLI) | Automated upload via command line | Tenant API key and cURL |
| FTP/SFTP | Scheduled file delivery from servers | FTP/SFTP server access and Peak IP allowlist |
Using signed URLs
Uploading files with signed URLs is a two-step process:
- Generate a signed URL by sending the file name to
https://api.peak.ai/file/signedurl/clientwith your tenant API key. - Upload the file to the generated signed URL with a
PUTrequest.
You can complete these steps using:
- Uploading files via command line with signed URLs
- Uploading files via Postman with signed URLs
- Uploading files via Python with signed URLs
Next steps
After a file upload, create a file feed to ingest the data into the data warehouse. For details, see Creating a file feed from Files.
