Get One Online Archive

You can retrieve an online archive using its ID. You can also view an online archive from the Atlas UI. You must have GROUP_READ_ONLY (Project Read Only) role to retrieve an online archive.

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

To learn how to configure API access for an Atlas project, see Configure Atlas API Access.

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.
