How can I get the data stored from Taxamo?

You can use the Taxamo RESTful API to retrieve all transactions and other data.

See this endpoint for an example: https://dashboard.taxamo.com/apidocs/api/v1/transactions/docs.html#GET

Once the data is retrieved you can download the transaction data for storage in your own system.
