Mercado Pago via dLocal

Mercado Pago via dLocal redirects the customer to Mercado Pago, where they approve the payment using their wallet balance, a stored card, or Mercado Crédito. Mercado Pago is the payments arm of Mercado Libre and one of the most widely held wallets in Latin America. Through dLocal it is available in six markets, each with its own local currency.

One off payment	Refunds	Recurring	Cancel
✓	✓	x	x

Mercado Pago via dLocal is asynchronous. dLocal confirms the payment by webhook once the customer approves it in Mercado Pago, so fulfil orders only on a final status. Full and partial refunds are supported, and a payment can be refunded more than once.

Supported markets

Market	`order.countryCode`	`currencyCode`
Argentina	`AR`	`ARS`
Brazil	`BR`	`BRL`
Chile	`CL`	`CLP`
Colombia	`CO`	`COP`
Mexico	`MX`	`MXN`
Uruguay	`UY`	`UYU`

To route payments in Chile in CLP, you must request special currency access from Primer. Raise a ticket on the Support Portal before you go live in Chile — without it, CLP payments cannot be processed.

Prepare the SDK for payments

Web

Android

Use the payment method type DLOCAL_MERCADO_PAGO wherever the code below references YOUR_PAYMENT_METHOD_TYPE.

Primer Checkout (recommended)
Universal Checkout (legacy)
Headless Universal Checkout (legacy)

Primer Checkout is our latest web SDK, built around declarative web components. Once Mercado Pago via dLocal is enabled in your Dashboard, the default <primer-checkout> layout renders it automatically alongside your other methods — no payment-method-specific markup is required.

<primer-checkout client-token="your-client-token"></primer-checkout>

Custom layouts

Only reach for primer-payment-method if you’re building a custom layout and need to place Mercado Pago via dLocal at a specific position. The element only renders when the type is enabled in your Dashboard and returned by the server for this checkout.

<primer-checkout client-token="your-client-token">
  <primer-main slot="main">
    <div slot="payments">
      <primer-payment-method type="YOUR_PAYMENT_METHOD_TYPE"></primer-payment-method>
    </div>
  </primer-main>
</primer-checkout>

For dynamic rendering based on what the server returns, listen to primer:methods-update or use primer-payment-method-container for declarative filtering.

Set up redirects

If Mercado Pago via dLocal can’t be shown in a popup, Universal Checkout redirects the customer back to your site using the returnUrl passed in the redirect options. See Handle redirects & deep links for the full flow.

const options = {
  container: "#checkout-container",
  redirect: {
    returnUrl: "https://mystore.com/checkout",
  },
  onCheckoutComplete({ payment }) {
    console.log("Checkout complete.", payment);
  },
};

Show Universal Checkout

Mercado Pago via dLocal is automatically presented when calling Primer.showUniversalCheckout.

import { Primer } from "@primer-io/checkout-web";

try {
  await Primer.showUniversalCheckout(clientToken, options);
} catch (e) {
  // handle error
}

Check the customization guide to learn how to customize payment method buttons.

Create a RedirectPaymentMethodManager for Mercado Pago via dLocal using createPaymentMethodManager, then call start() to begin the redirect flow.

const manager = await headless.createPaymentMethodManager("YOUR_PAYMENT_METHOD_TYPE");

if (manager) {
  manager.addEventListener("click", () => {
    // Optional: run custom logic before the redirect flow starts.
  });

  await manager.start();
}

Refer to the full guide for handling payment methods with redirect.

Use the payment method type DLOCAL_MERCADO_PAGO wherever the code below references YOUR_PAYMENT_METHOD_TYPE.

Set up redirects

Redirect-based payment methods present a webpage or open a third-party app for the customer to authorize the payment. To return to your app once the customer has authorized the payment, include the urlScheme parameter when configuring PrimerPaymentMethodOptions.

let settings = PrimerSettings(
  // ...
  paymentMethodOptions: PrimerPaymentMethodOptions(
    urlScheme: "your-url-scheme://" // e.g. primer://, yourscheme://
  )
  // ...
)

When the customer is redirected back to your app, iOS calls application(_:continue:restorationHandler:). Forward the call to the Primer SDK so the checkout can continue the flow.

import PrimerSDK
import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
  // ...
  func application(
    _ application: UIApplication,
    continue userActivity: NSUserActivity,
    restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void
  ) -> Bool {
    return Primer.shared.application(
      application,
      continue: userActivity,
      restorationHandler: restorationHandler
    )
  }
}

Universal Checkout (drop-in)
Headless Universal Checkout

Mercado Pago via dLocal is automatically presented when calling Primer.shared.showUniversalCheckout.

class MyViewController: UIViewController {
  func startUniversalCheckout() {
    Primer.shared.showUniversalCheckout(clientToken: self.clientToken)
  }
}

Check the customization guide to learn how to customize payment method buttons.

Mercado Pago via dLocal requires a Native UI Manager to be presented to the customer.

// 👇 Create the payment method manager
let nativeUIPaymentMethodManager = try PrimerHeadlessUniversalCheckout.NativeUIManager(
  paymentMethodType: "YOUR_PAYMENT_METHOD_TYPE"
)

// 👇 Show the payment method
try nativeUIPaymentMethodManager.showPaymentMethod(intent: .checkout)

See NativeUIManager.init for the full API. As many redirect-based payment methods share this approach, we recommend centralizing the implementation — see the worked example in the Native UI Manager guide.

Use the payment method type DLOCAL_MERCADO_PAGO wherever the code below references YOUR_PAYMENT_METHOD_TYPE.

Universal Checkout (drop-in)
Headless Universal Checkout

Mercado Pago via dLocal is automatically presented when calling Primer.instance.showUniversalCheckout.

class CheckoutActivity : AppCompatActivity() {
  private fun setupObservers() {
    viewModel.clientToken.observe(this) { clientToken ->
      showUniversalCheckout(clientToken)
    }
  }

  private fun showUniversalCheckout(clientToken: String) {
    Primer.instance.showUniversalCheckout(this, clientToken)
  }
}

Mercado Pago via dLocal requires a Native UI Manager to be presented to the customer.

// 👇 Create the payment method manager
val nativeUiManager = PrimerHeadlessUniversalCheckoutNativeUiManager.newInstance("YOUR_PAYMENT_METHOD_TYPE")

// 👇 Show the payment method
nativeUiManager.showPaymentMethod(this, PrimerSessionIntent.CHECKOUT)

See NativeUiManager.newInstance for the full API. As many redirect-based payment methods share this approach, we recommend centralizing the implementation — see the worked example in the Native UI Manager guide.

Test in sandbox

Connect your dLocal test account to your Primer Sandbox environment. Toggle Test mode in the dLocal dashboard before copying your credentials, sandbox and production credentials are different. Run the following for each market you intend to support.

Create a client session with order.countryCode, currencyCode and customer.nationalDocumentId set for that market.
Select Mercado Pago at the checkout.
Complete the payment on the Mercado Pago hosted page.
Drive a PAID callback from dLocal.
Confirm Primer resumes the payment once and the final status is Settled.

Also confirm that the correct Mercado Pago branding and logo are shown for the country under test.

Market	`order.countryCode`	`currencyCode`	Test document
Brazil	`BR`	`BRL`	CPF request a valid-format document from dLocal
Mexico	`MX`	`MXN`	RFC or CURP request a valid-format document from dLocal
Argentina	`AR`	`ARS`	CUIT or DNI request a valid-format document from dLocal
Chile	`CL`	`CLP`	RUT request a valid-format document from dLocal
Colombia	`CO`	`COP`	CC or NIT request a valid-format document from dLocal
Uruguay	`UY`	`UYU`	CI request a valid-format document from dLocal

Go live

Ensure to use production credentials, and confirm with dLocal that Mercado Pago is enabled on your production account for each market you intend to support. Make sure order.countryCode and currencyCode match one of the supported markets on every payment you route to it. If you are going live in Chile, confirm your CLP currency access has been granted by Primer.
