# Integrating Link with the Payment Element

**Does the Payment Element support Link?**
Yes, Link can be enabled in the [Payment Element](https://stripe.com/docs/payments/link/accept-a-payment).
**How do I test Link when integrating it with the new Payment Elements?**
You can test Link by following the instructions in the testing section of the [Link accept-a-payment guide](https://stripe.com/docs/payments/link/accept-a-payment?platform=web#web-test-the-integration).
**I’m not getting the SMS with the 6 digit authentication code when testing – what do I do?**
In test mode, you will not receive a 6 digit SMS one time passcode. Instead, you should use the passcodes listed in our testing section of the [Link accept-a-payment guide](https://stripe.com/docs/payments/link/accept-a-payment?platform=web#web-test-the-integration).
**How does Link work for end-customers? Is it opt-in or opt-out?**
* For first-time users, a component will appear at checkout that says, “Save my info for secure 1-click checkout”. The customer can opt in by filling in their phone number. Stripe will remember all the information on this page (email, address, payment details).
* For returning customers, we recognize their email address, prompt them to authenticate with a one-time code sent via SMS, then autofill their details so they can check out.
**Can I auto-fill any additional fields like email or phone number so that the customer can reduce the number of steps required to sign up for Link?**
* Yes, you can prefill the customer’s email address and phone number.

**Why can’t I see the card details (last 4 of card, card brand, billing zip) for a Link payment in my dashboard?**
Link payments in the Stripe Dashboard will show the payment method as “Link” and will not expose any of the card details (e.g,. card brand, last 4 of card, or card postal/zip code).
