Podemos usar o mesmo gateway de pagamento para vários formulários? Meu formulário não solicita detalhes de pagamento.

posso criar mais de um formulário com mesma forma de pagamento?

temos um formulário de compra de produto, duplicamos o mesmo pois as informações são diferente, porem ao finalizar a compra ele não pede dados de pagamento 

Hi HotelPremiumCampinas,

Thanks for reaching out to Jotform Support. Unfortunately, our Spanish Support agents are busy helping other Jotform users at the moment. I'll reply based on your English reply, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Spanish, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Now, coming back to your question about using the same payment gateway for your forms. Sure, you can do that. You'll need to reconnect the payment gateway. When I checked your cloned form, I saw that the Product List field is already connected to Stripe. Here's the screenshot:

You'll be asked for the payment details after you fill in your form and click on the To send button. Take a look at the screencast below:

Can you try it again and see how it goes? I also cleared your form caches. If you run into any issue, let us know. You might also want to check out this guide about How to Integrate Stripe Checkout With Jotform.

Give it a try and reach out again if you have any other questions.
