How can I implement payment intent in an online store?

[Itsshroff]

I am looking for any developer who has previously implemented payment intent. When the customers complete their order, they get redirected in iframe to complete their payment with the external payment provider. When payment is complete, your customer is redirected to the Shopify store to view their order summary and confirmation page.

Basically we don't want to use the payment apps in Shopify instead we want to use their APIs which will allow us to collect payment as a payment intent.
