# Batch triggers **Batch triggers** let you trigger multiple runs for a single workflow at once. Unlike the [Looping over a list \*inside\* a workflow](/flow-control/iterators.md), Batch Triggers aren't restricted in terms of how many runs they can start. ## About batch triggers You will find batch triggers inside the trigger menu for each app. Below the list of regular "event-based" triggers, you'll find a list of the supported batch triggers for that app. Apps typically only have one batch trigger option available, but some have multiple types.

## Setting up a batch trigger ### 1. Configure it to start on demand or on a recurring schedule When selecting a batch trigger, you'll first need to select whether you will want to * Manually kick off the batch every time "on demand," or * Start a batch of runs on a recurring schedule (e.g. every day/month/etc) ([more here](#id-3.-recurring-only-specify-the-schedule))
### 2. Specify for which items it should start runs First, select whether runs should be started for every item (e.g. every row in the selected spreadsheet), or only a subset. Typically you'll want to only run for a subset, and specify filters.
If you've selected to only trigger runs for a subset of items, you'll need to specify filters. The "Preview" area below it will show a preview of the items that match your filters and that it would trigger runs for.
### 3a. \[Recurring only] Specify the schedule If you've selected a recurring batch trigger [above](#id-1.-configure-it-to-start-on-demand-or-on-a-recurring-schedule), specify the recurring schedule below the Preview section:
### 3b. Starting a batch on demand/manually To start a batch manually, click 'Start batch' in the header of the trigger. Note: This button will only appear when you have a complete workflow set up (i.e. there are steps and no errors).
