API imports and blockchain imports retrieve all your transactions every 24 hours.
If you delete a transaction, it will be automatically re-imported within the next day.
To bypass this re-import, you can:
- Switch the importer from "automatic" to "manual" (only for API imports)
- Delete the API key or the coin address
- Set a "start date" for the importer on the API/blockchain importer page
Example of setting a start date for the ETH blockchain importer:
1) Click on "Edit"
2) Enter your start date and click on Update:
(Please note that your date format may differ, so add it accordingly)
