Hi there German!
Don here from Shopify. :)
Depending on which country your store is operating in, you may already have the option to add PayU Latam!
We can see here, for example, in the list of payment gateways available for use in Colombia with your Shopify store that PayU Latam is available there!
If your store is not based in Colombia, just let me know what country you are operating from and we can check the list there to see if PayU Latam is available there.
German, you can also take a look at EBANX (https://business.ebanx.com/en/ebanx-payment-gateway-for-shopify). With EBANX you can offer the most popular payment methods in several Latin American countries.
Hope this helps!
