Bubble.io Workflows Explained: A Complete Beginner’s Guide
Workflows are the logic engine behind every Bubble app action. Every workflow type explained, a six-step build walkthrough with debugger guidance, and the five most common mistakes new builders make.
The Logic Engine Behind Every App Action
In Bubble.io, a workflow is the mechanism that makes things happen. When a user clicks a button, submits a form, or loads a page, a workflow runs. Workflows are the logic layer of every Bubble application: they create records, send emails, call APIs, navigate users to new pages, and update data. This guide explains every workflow type, how to build them correctly, and the patterns that separate reliable workflows from fragile ones.
Page, General, Backend, and Scheduled
| Type | When It Runs | Best For |
|---|---|---|
| Page Workflow | When a page element is interacted with (click, hover, input change) or on page load | UI interactions, navigation, showing and hiding elements |
| General Workflow | When triggered by a custom event from another workflow | Reusable logic shared across multiple triggers |
| Backend API Workflow | Triggered by another workflow, an API call, or a schedule | Server-side processing, webhooks, long operations |
| Scheduled Workflow | At a specific future datetime or on a recurring schedule | Reminder emails, nightly aggregations, trial expiry actions |
Step-by-Step: A Complete Create Record Workflow
Drag a Button element onto your page. Give it a descriptive label like ‘Create Project’. Double-click to open settings and give it an ID you will recognise.
Click the button element, then click ‘Start/Edit workflow’. This opens the Workflow editor with a trigger already set to ‘When [button] is clicked’. Every step you now add runs when this button is clicked.
Only when
: Input_project_name’s value is not empty
AND
: Current User is logged in
Action
: Create a new thing (Project)
name
= Input_project_name’s value
workspace
= Current User’s current_workspace
created_by
= Current User
status
= Active (option set)
Add action: Reset inputs. Select the Input_project_name element. This clears the field so the user can immediately create another project without manually deleting the previous value.
Click the Bug icon to enable Bubble’s debugger. Run the workflow in step-by-step mode to inspect the actual value of every condition and step result as it executes. This is the only reliable debugging tool for complex workflows.
What New Bubble Builders Get Wrong
| Mistake | What Happens | Fix |
|---|---|---|
| No role check on sensitive steps | Any user can trigger admin actions | Add: Only when Current User’s role is Admin |
| Missing workspace on created records | Records not scoped to tenant | Always set workspace = Current User’s current_workspace |
| Frontend workflow for heavy operations | Fails if browser closes mid-execution | Move operations over 3 steps to backend API workflow |
| No error handling after API calls | Silent failures confuse users | Add ‘detect error’ condition after every API call |
Q: What is the difference between a workflow condition and a step condition?
A workflow condition controls whether the entire workflow runs. A step condition (Only when on a specific step) controls whether that individual step runs. Other steps can still run even if one step’s condition fails.
Q: Can one workflow trigger another?
Yes. Use ‘Trigger a custom event’ to start a general workflow. Use ‘Schedule API workflow’ to trigger a backend workflow from a frontend workflow.
Q: What happens if a step fails?
Bubble stops at the failed step and does not run subsequent steps. Build error handling into every workflow that calls an external API.
