Capture Payment and Create Card

[MateoLa]

Hi.
I want to save the card the firt time I capture a payment with it.
How can I do that if I only have one token coming from the client?
Thanks.

Hi @MateoLa , how are you?

If I understand you correctly, you want to add a card to a customer, right?
If that is the case, you can create a customer like this:

sdk = Mercadopago::SDK.new('<ACCESS_TOKEN>')

customer_request = {
  email: '<EMAIL>' 
}

customer_response = sdk.customer.create(customer_request)
customer = customer_response[:response]
puts customer

And for adding a card to a customer:

customer_id = '<CUSTOMER_ID>'

card_request = {
  token: '<CARD_TOKEN>',
  payment_method_id: '<PAYMENT_METHOD_ID>'
}

card_response = sdk.card.create(customer_id, card_request)
card = card_response[:response]
puts card

Thank you for using our SDK!
Any doubt, let us know!

Hi Rhames. Thank you for your response.
I would like to ask you if the same <CARD_TOKEN> you used to save the card can be used again to capture the payment or you must retrieve a new one? In the last case you should ask the customer to enter the card data twice.
Thanks, Mateo.

Hi @MateoLa!
After the card has been saved, the following payments can be made as described in this documentation.

Thanks Rhames for the document, I had seen it.
I was trying to say at the first purchase, when you save the card. You have to ask the customer to enter the CVC code again. The first time you ask the customer for the card details and you can save it. Then you have to ask the customer again for the CVC to capture the payment. Is this true or is there any way to do both events at the same time without asking the customer twice?

You can try the following: try to make the payment, and if the payment is successful use the same token to save the card for the user.
Remember that the token is limited to one transactional use only, but I believe you can use the same token to save the card.

Ok. I'll try.
I think I've try it before but I'm going to give it a second look. I let you know.
Thanks.
