Automations only run if they are triggered in some way. There are different ways to do that:
1. Inside of miniExtensions:
Manually, by clicking the "run" button on our website.
Schedule it to run regularly using the Advanced options on the Run tab.
2. Outside of miniExtensions:
Trigger it with Airtable Automations (e.g. for any new record).
Trigger it by a Webhook. A Webhook is a unique URL for your automation that you call from another app (e.g. Zapier). Every time it’s fired (accessed), it will trigger the automation to run.
When triggered automatically, the automation will run in the same way as if you clicked on the run button on the settings page manually.
Keep in mind that, by default, the automation would skip any record that already contains data in its output field. It will only go through records that haven't been processed, unless you select the Overwrite option as explained here.
