The `/ping` endpoint enables you to validate connectivity between your client application and the Marqeta platform. You can use these endpoints to validate connectivity to your production environment, as well as to the public or private sandbox testing environment.

  Perform ping
</h2>

**Action:** `GET`\
**Endpoint:** `/ping`

{/* <EndpointCard
title="Returns a heartbeat to the consumer"
path="/ping"
method="get"
/> */}

To validate that the Marqeta server is available and responsive, send a `GET` request to the `/ping` endpoint. The response indicates whether the ping was successful, the version and revision number of the environment, and a timestamp.
