# Manual

Run a workflow by hand, with the Run button or the API.

## Start a workflow

### When someone runs it

Starts only when a person presses Run or calls the run endpoint. Nothing fires it on its own: no URL, no schedule, no polling.

For a step-by-step guide, see [Run a workflow by hand](https://docs.gorunner.io/build/run-by-hand).

Not in your list? See [When an app isn’t here](https://docs.gorunner.io/apps/when-an-app-isnt-here#q-not-in-list).

## For developers

In the API, which calls apps pieces, Manual is `pieceId: "manual"`. Its trigger is `manual` / `manual`. [Get an app](https://docs.gorunner.io/api/apps/get-app) returns every field.
