Cards

Mercado Pago Tarjetas (Checkout API) is an app that allows transparent payments with debit or credit cards, where the entire checkout process happens within the online store environment, without the need to redirect to an external page. In addition to providing greater control in the customization and integration process, it reduces cart abandonment and increases the possibility of conversion.

To install the Mercado Pago Tarjetas checkout on a Shopify store, we offer the two installation models below.

Install via Shopify admin panel

  1. Go to your Shopify store.
  2. In the store's administration panel, click on Settings in the bottom-left corner of the page.
  3. Once there, select the Payments option from the left-hand side menu.
  4. In "Payment providers", click on Choose provider.
  5. On the "External payment providers" screen, serach for the app "Mercado Pago Tarjetas".
  6. Once you've found it, select it and click Install. Carefully read the information about the requested permissions and click Install again.
  7. After accepting the requested permissions, click Manage account to input your credentials and link your Mercado Pago account to the store.
The credentials are responsible for identifying the account collecting the payments that you will receive in your store.
  1. In the Mercado Pago admin, go to Your integrations and select your application. If you haven't created an application yet, access the developer Dashboard documentation to learn how to create one.
  2. Click on Production credentials in the left menu. Copy the public_key and access_token.
  3. Return your store settings on Shopify and enter your production credentials (access_token and public_key) in the corresponding fields, being careful not to swap the fields when copying and pasting the credentials.
Note
Once entered, the credentials will no longer be required for future installations of Mercado Pago apps for Shopify.

Remember that, when changing the Shopify password, it is necessary to renew your credentials. To do so, follow the instructions in the Best practices for credentials documentation. Then, to update them on your Shopify account, click on Manage account and fill in the corresponding fields with your access_token and public_key being careful not to swap the fields when copying and pasting the credentials.
