File or API: Which should I use?

If you need real time validations (for example, if you want to verify your users' email addresses during the sign up process and reject them if they are invalid, the API is going to be the faster and easier choice. If you need to validate lists, either as a one off or once every few days/weeks, then it's easier to use the browser and upload all your emails at once.

AutoPay

./getting-started/auto-pay

AutoPay is a feature that allows you to automatically replenish your account when your credit balance gets low. This feature ensures that you don't run out of credits when using our API to validate emails.

In order to use this feature, you need to make at least one purchase using the "Pay with Card" option on the "Buy Credits" screen. Then you will be able to add or delete payment methods, but only one payment method is allowed to be active.

Be sure to "Check" the Enable Automatic Payment button and click "Save Changes".
