# Public Requests w/Reply

A [Public Request with Reply](/worker-apis/public-requests-w-reply.md) is a message that can be sent to a Worker from an external source, such as from a Worker's Caller (within a Workers application), from another LabVIEW application or framework, or from TestStand. The VI that sends the message will wait until a Reply message is received back from the Worker that the Request message was sent to. You can create and edit a Worker's Public Request with Reply in the **Requests w/Reply tab** of the Public API Builder tool, as shown in the image below:
