Scripts
Cleanup
A configrable automation script that cleans up the AWS and Dwolla environment from test data. To be run pre-deployment in production. Script allows accounts to be preserved by adding the ‘Email’ in ‘preserve_users.txt’ file.
Webhook
A webhook created for dwolla, that handels clearing of ACH transactions. In case of successful ACH clearing, it sends out a text to the customer with transaction details. In case of unsuccessful ACH clearing, it sends out a text to the customer with transaction details and Dracker entry so the customer can track back and re-attempt to settle the payment.
