Trigger

Initiate a flow whenever a specific event occurs in a connected app

The Trigger component starts your flow automatically when a specific event occurs in a connected app — such as a new message in Slack, a form submission, or a record update in a CRM. Use it when you want your automation to run in response to real-time activity rather than on a manual or scheduled basis.

• You can add this component by searching for Trigger in your flow. Once added, you’ll first need to select an app from the available list or search for the required one.

• After selecting the app, connect and authenticate your account to enable access.

• After saving, the Trigger will automatically listen for the selected event.

Based on the selected app, a list of Trigger events will appear.

In the case of Slack, when a message is posted in the specified channel, the trigger will activate and send a message from Fastn to that channel.

• Next, select the account ID associated with the connection, for example, Fastn.

• In the Headers section, add the required key–value pairs for authentication or configuration. Once you’ve entered all details, click Save to finalize this step.

• You can choose the event that should start your flow. For example, when integrating with Slack, you can select the Message Posted trigger event.

• You can test this step by clicking the Test button in the top right corner.

The console will display the result, and you’ll see the message sent to your selected Slack channel.
