Does Bold work with Mercado Pago, PayU, Wompi, or World Pay?
Mercado Pago, PayU, Wompi, and World Pay are not supported by Shopify as payment gateways for subscriptions. Because Bold Subscriptions works with Shopify’s checkout, you must connect an eligible payment gateway in Shopify. Bold Subscriptions is compatible with Shopify Payments, PayPal Express, Authorize.net, and Stripe. Read more about this in our Help Center article: https://support.boldcommerce.com/hc/en-us/articles/360054884151-Payment-Options-Eligibility-in-Subscriptions-for-Shopify-Checkout
If you having trouble connecting a payment gateway to your store, please reach out to Shopify for support.
