# Send payment links

> Send a checkout link to customers via SMS or email. Ideal for phone orders, invoicing, or any scenario where the customer isn't on your website.

Send a payment link directly to a customer's phone via SMS or email. This is useful for phone orders, manual invoicing, remote sales, or any situation where the customer isn't browsing your website.

You create a checkout session with the customer's phone number, and Dintero delivers the link automatically. The customer opens it, pays on the Dintero-hosted checkout page, and you receive the result through your normal callback flow.

## Integration steps

<Steps>
  <Step title="Choose how to send links">
    There are three ways to send payment links:

    | Method                         | Best for                                                          |
    | ------------------------------ | ----------------------------------------------------------------- |
    | **Payment Link in Backoffice** | Manual one-off payments, no code required                         |
    | **Payment profile setting**    | Automatically send SMS for every session using a specific profile |
    | **API configuration**          | Full control, enable SMS per session in your code                 |

    For the no-code approach, go to **Payment Link** in Backoffice, choose **Send by > SMS/Push**, and enter the phone number. No API integration needed.
  </Step>

  <Step title="Enable SMS in your payment profile (optional)">
    If you want SMS delivery for all sessions using a specific profile, open [Backoffice](https://backoffice.dintero.com/) and enable SMS on the payment profile. Every session created with that `profile_id` will automatically send a link.
  </Step>

  <Step title="Create a session with SMS delivery">
    For API-driven delivery, create a checkout session and include the customer's phone number and SMS configuration in the request body. Dintero sends the SMS as soon as the session is created.

    Include `order.amount`, `order.currency`, the customer's phone number, and your callback/return URLs as with any session.

    See [Payment link by SMS](/docs/checkout/payment-link-by-sms) for the full configuration options.

    <Info>
      SMS messages are not sent for test sessions (`T` prefix accounts). Use production credentials to verify SMS delivery.
    </Info>
  </Step>

  <Step title="Customer receives and pays">
    The customer receives an SMS or push notification with a link to the Dintero-hosted checkout page. They open it, select a payment method, and complete the payment. The experience is the same as any Dintero Checkout.
  </Step>

  <Step title="Handle the payment result">
    The result is delivered to your `callback_url` and through [webhooks](/docs/checkout/checkout-webhooks), just like any other checkout session. Capture, void, and refund through the [Transactions API](/docs/checkout/transaction-management).
  </Step>
</Steps>
