In your Paperform dashboard, click on the avatar in the top right corner.
Select "Account Settings" located in the sidebar, and then navigate to Account Services.
Add a new payment account:
Click the "Connect" button for your preferred payment provider.
Follow the prompts to authorize Paperform to have access to your payment account.
After authorizing Paperform, you will be returned to the Account Services page and your selected payment account will be in the list of connected services.
Note that you'll need to have a payment account set up with a supported payment provider in order to connect it to your Paperform account. So the first thing you need to have in place is a registered account with either Stripe, Braintree, PayPal Business, or Square.
Once connected to your account, payment accounts can then be added to select forms in the form editor so you can start collecting payments from your customers.
