# Update an aggregation of a Tulip Table

Put/tables/{tableId}/aggregation/{aggregationId}

Updates an aggregation in a Tulip Table by the aggregation id. Requires the `table-queries:write` API key scope.

SecurityHTTPType basic

Access to the Tulip API requires the use of [HTTP Basic Authentication](https://datatracker.ietf.org/doc/html/rfc7617) using the credentials of an active [Tulip API Token](https://support.tulip.co/docs/set-up-a-tulip-api). All requests require the `Authorization` HTTP header with the `Basic` scheme to provide API credentials unless otherwise noted.

API tokens can be configured with a set of *scopes* which determine what parts of the API that specific token has access to. Security best practices dictate that API credentials be given the minimum set of capabilities required to fulfill their intended purpose. For example, an API token created for use in an integration that is only designed to use the Tables API should probably only be given the `tables:read` and `tables:write` scopes. In this way you can minimize risk in the event that API credentials are compromised. API endpoints will document what API token scopes are required to access that endpoint in their descriptions. If a request is made to an endpoint with an API token which does not have the required scopes, the response will be an authorization error.
