Understand What a Custom Event Is     Custom events in Bubble.io allow you to create reusable workflows that can be triggered from multiple places within your application. These events can help you streamline and modularize your workflows, making your development process more efficient.   Create a New Custom Event     1.   Open your Bubble.io application. 2.   Navigate to the "Workflow" tab on the left side of the editor. 3.   Click on the "Click here to add an event..." button. 4.   Select the "Custom" option at the bottom. 5.   You'll see a new event with the title "Do when it is true." Rename this to something more specific to your need (e.g., "My Custom Event").   Define Actions Within the Custom Event     1.   Click on the "Click here to add an action" button within your newly created custom event. 2.   Choose the action type you need from the list. This could be anything from navigating to a page, modifying a thing, or triggering an API workflow. 3.   Configure the selected action as required.   Trigger the Custom Event     1.   Go back to the Workflow tab. 2.   Click on the "Click here to add an event..." button to create a new event that will be used to trigger your custom event. 3.   Choose an appropriate event type (e.g., when a button is clicked, when a page is loaded). 4.   Once the event is created, click on the "Click here to add an action" button within this event. 5.   Select the "Trigger a custom event" action. 6.   In the dialog box that appears, choose your previously created custom event from the dropdown menu.   Test Your Custom Event     1.   Go to the preview mode in Bubble.io. 2.   Trigger the event that you set up to trigger your custom event (e.g., click the button you associated with the custom event). 3.   Verify that the actions defined in your custom event are executed correctly.   Organize and Maintain Your Custom Events     1.   Give meaningful names to your custom events to make them easier to identify. 2.   Document what each custom event does, either in a separate document or within the notes section of your Bubble.io editor. 3.   Group similar custom events together for better organization. 4.   Regularly review and update your custom events to ensure they remain relevant and efficient.
