Duplicate Records Being Created in Base44 Database
Your Base44 application is creating duplicate records in the database. Users submit a form once but two or more identical records appear in the table. This can also happen through automated workflows or API integrations that fire multiple times.
Duplicate data causes serious problems: incorrect counts in dashboards, duplicate email notifications being sent, billing errors, and general data integrity issues that compound over time.
The duplicates may be exact copies or near-duplicates where most fields match but timestamps or auto-generated IDs differ slightly, indicating the same action was triggered multiple times in quick succession.
Common Causes
- The form submit button doesn't disable after the first click, allowing users to click it multiple times
- A workflow trigger fires multiple times for the same event (e.g., on both create and update)
- The page navigates on submit but slow network causes the user to click again before navigation
- No unique constraints are set on the table to prevent duplicate entries
How to Fix It
The quickest fix is to add a unique constraint on a combination of fields that should be unique (e.g., email address, or a combination of user ID and date). This prevents duplicates at the database level regardless of how many times the form is submitted.
Check if your form's submit action properly disables the button or shows a loading state after the first click. Also review any automated workflows that create records to ensure their trigger conditions don't cause multiple executions.
For apps already containing duplicates, a developer can help write a cleanup script to deduplicate existing data and set up proper constraints to prevent future duplicates.

Get HelpFrequently Asked Questions
Why are duplicate records appearing in my Base44 database?
The most common cause is users clicking the submit button multiple times. Add a unique constraint on key fields and disable the submit button after the first click.
How do I remove existing duplicate records in Base44?
You'll need to identify duplicates by their shared field values and manually delete the extras. For large datasets, a developer can automate this cleanup.
