Take One On-Demand Snapshot


Groups and projects are synonymous terms. Your {GROUP-ID} is the same as your project ID. For existing groups, your group/project ID remains the same. The resource and corresponding endpoints use the term groups.

The Atlas API uses HTTP Digest Authentication. Provide a programmatic API public key and corresponding private key as the username and password when constructing the HTTP request.

For complete documentation on configuring API access for an Atlas project, see Configure Atlas API Access.

Base URL:

Take one on-demand snapshot. Atlas takes on-demand snapshots immediately, unlike scheduled snapshots which occur at regular intervals. If there is already an on-demand snapshot with a status of queued or inProgress, you must wait until Atlas has completed the on-demand snapshot before taking another.

You must have the Organization Owner or Project Owner role to successfully call this endpoint.

All requests to this endpoint must originate from an IP address on the Atlas user’s API whitelist. For complete documentation on configuring API whitelists, see Enable API Whitelisting for Your Organization.
