# Deprecated API rate limits **(FREE SELF)**

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/68645) in GitLab 14.4.

Deprecated API endpoints are those which have been replaced with alternative
functionality, but cannot be removed without breaking backward compatibility.
Setting a restrictive rate limit on these endpoints can encourage users to
switch to the alternatives.

## Deprecated API endpoints

Not all deprecated API endpoints are included in this rate limit - just those
that might have a performance impact:

- [`GET /groups/:id`](../../../api/groups.md#details-of-a-group) **without** the `with_projects=0` query parameter.

## Define Deprecated API rate limits

Rate limits for deprecated API endpoints are disabled by default. When enabled, they supersede
the general user and IP rate limits for requests to deprecated endpoints. You can keep any general user
and IP rate limits already in place, and increase or decrease the rate limits
for deprecated API endpoints. No other new features are provided by this override.

Prerequisites:

- You must have administrator access for your instance.

To override the general user and IP rate limits for requests to deprecated API endpoints:

1. On the top bar, select **Main menu > Admin**.
1. On the left sidebar, select **Settings > Network**.
1. Expand **Deprecated API Rate Limits**.
1. Select the checkboxes for the types of rate limits you want to enable:
   - **Unauthenticated API request rate limit**
   - **Authenticated API request rate limit**
1. _If you enabled unauthenticated API request rate limits:_
   1. Select the **Maximum unauthenticated API requests per period per IP**.
   1. Select the **Unauthenticated API rate limit period in seconds**.
1. _If you enabled authenticated API request rate limits:_
   1. Select the **Maximum authenticated API requests per period per user**.
   1. Select the **Authenticated API rate limit period in seconds**.
