# Service Checks

The service check endpoint allows you to post check statuses for use with monitors. Service check messages are limited to 500 characters. If a check is posted with a message containing more than 500 characters, only the first 500 characters are displayed. Messages are limited for checks with a Critical or Warning status, they are dropped for checks with an OK status.
