How to remove events from amplitude?

On Nov 4-9, 2021, my transaction system has a problem causing Event "paymentSuccess" to be sent twice in the same period, can I remove or drop filter this event? because it affects the repurchase data.

So you accidentally sent an event twice and want to remove it? Unfortunately, historical data in Amplitude is immutable and not changeable or editable. However, an option is to use the Export API, export all your project data and clean it (remove unwanted events) and then backfill into a new project.

Export all event data using Export API and clean the values on events
Set up a new project
Self backfill all this new cleaned data into a new project see this guide for details and for a link to Export API https://developers.amplitude.com/docs/self-data-backfill-guide
Delete old project

This would be the best way at the moment to handle this. The other solution is to use our User Privacy API to remove all data about one user, but this would remove all their “healthy” data too. So it is up to you to decide which you would choose. I hope this helps!

Hello,

Does this removes the event quota limit affected by the first project ingestion?
Meaning, if the first ingestion took 10% of your quota, do you get that 10% back after deleting?

Hello, Is there a way to make a query like: “Give me all the users that have the user property X equal to 10”, by using just any of the APIs, without making a cohort first through the Amplitude’s UI? Thank you!
