PayPal Rest API Direct Payments

I currently have my site accepting payments through PayPal. I use the PHP SDK for the REST API to handle this. This is the steps I take to handle payments through my site:

  1. Create a payment with the intent set to "Sale", payment method set to "paypal" and the redirect url set to the confirmation page.
  2. On the confirmation page I store the returned paymentId and PayerID (from the query string) to use in step 3.
  3. Once the user confirms the order I then execute the payment passing in the paymentId and PayerID stored in step 2.

This works a treat. However I'd like to give the user an option of processing the payment via PayPal (like above) or via my site (using PayPal direct payments).

For the direct payments I have been able to successfully create the payment by setting the intent to "Sale", payment method to "credit_card" and passing in the appropriate card details. However I'm not sure whether I need to execute the payment afterwards like I do above or whether the payment automatically goes through.

If I do need to execute the payment then how do I get the paymentId and PayerID? If I don't need to execute the payment then this presents a problem as I'd like the user to confirm the payment. I could move the create payment stuff to only execute once the user confirms the order for direct payments but then I can't validate the card details after the user enters them. I was wondering if there was a better way to handle this?

I'd appreciate it if someone could help clear this up. Thanks

You'll just need to process the first step (create the payment) when it comes to a credit card (detailed here: https://developer.paypal.com/docs/integration/direct/accept-credit-cards/).

For your other question about the issues in not being able to have the user confirm, there are a few things you can do:

Since I think auth/capture is closer to what you're thinking about doing, let me dig in there a bit further. What you're essentially doing is authorizing the funds (holding them on the user's payment source) and then capturing them at a later time. This is the same premise as a hotel putting a hold on your credit card for incidentals, and later canceling the hold.

You can do all of this with the PayPal REST API. Here are the features you're looking for:

After you authorize, that's the point where the user can confirm and you can validate the card. Once everything is approved, you can then capture.

I know this isn't going to be an issue for you, but I'll mention it anyways. With auth/capture, authorized funds will be guaranteed to be there for only 3 days (honor period), but you can keep trying to capture the funds for 29 days. After those 3 days though, there isn't a guarantee that the funds will be present.

Hope that helps
