Receipts for purchase when I connect firstdata

I noticed that I can configure my Thank you page after the registrant (event registration form) submits.  Does a receipt from firstdata get emailed to the registrant as well?  It looks like I have to send the receipt separately from firstdata.

Also, where its the registration data held.  Is there a video I can view too see the complete process?

Usually, payment gateways and merchant services do not send emails to the persons who made payment unless it is made directly through them. The usual responsibility to send emails come from the seller or merchant service's clients. With this in mind, I believe it is safe to assume that they do not send emails to your form users.

If you wish for them to receive emails after making a purchase, your form can send an email buy adding an autoresponder to it. Please check this guide on how to set up an autoresponder email for your form: https://www.jotform.com/help/26-Setting-up-an-Autoresponder-Email

With regard to the data registration, the information is submitted through here and stored here in JotForm. Only the payment information and product items purchased are sent through the payment gateway (First Data) since they are the only ones capable of handling payments.

Thanks.
