You can both read from and write to databases with LogicLoop. When you set up a database like MySQL, Postgres or DynamoDB as an Action Destination, you can write updates back to your data. This is most commonly used to update the status of a row.
Click + New Action Destination and select PostgreSQL, MySQL or DynamoDB from the Create a New Action Destination popup. Then, enter your write-enabled database credentials.
You will now be able to define SQL you want to execute as an action to write back to your database when you create an Action Subscription in your rule.
