Nobl9 Annotations API (v1alpha)

Using Nobl9 Annotations API, you can create new annotations, fetch existing ones, or delete them.

You can find more detailed information on SLO Annotations in the respective section of Nobl9 documentation.

Annotations quota and rate limits

A quota limits the number of user annotations - there is a limit of 100 000 annotations per organization.

For rate limits, see the Rate limits section below.

Access Token

Generate access token

To generate access token, you must provide Authorization header with the Basic scheme.

The access token consists of your Client ID and Client Secret in the following format: clientId:clientSecret.

Rate limits for access token

All requests to the endpoint https://app.nobl9.com/api/accessToken are rate limited. An organization can make 1 request per 3 seconds.

The API returns the 429 HTTP status code when this limit is exceeded.

NOTE
Your token will be valid for 1 hour. Minimize the usage of this endpoint and reuse the token until it expires.

We recommend downloading your token once and reusing it in your CI/CD pipeline. Generating multiple tokens may exceed your rate limits.

Create single Annotation

You can update Annotations using a standard PUT request. This method will create a new annotation unless the annotation with the provided name (i.e. specified in the body of the JSON object) does not exist in the specified Project.

In addition, you must also provide all the remaining parameters even if you want to update just one of them (effectively, this command acts like a REPLACE command).
