PayPal Smart Buttons: Is there any way onApprove runs without the payment having completed?

So I have a website that uses PayPal smart buttons and I have a code that sends a the buyer the product when he buys the it. It uses a PHP file to send the product.

I have javascript code that calls PHP when the onApprove function runs.

I know that it is not the safest way to do but I found it really hard to use the API and it would be a lot of time to do it so I decided to do it this way.

But I ran into a problem when I don't receive the money on PayPal, but the program send the product to them. It sometimes works and sometimes not.

I am sure that the PHP code can only run when the onApprove runs so that is not the problem.

Is there any way that onApprove runs without the payment having completed?

Yes, definitely. onApprove runs whenever the payment is approved by the customer, meaning they clicked on the final approval action, usually phrased "Pay Now". This does not mean a payment has been captured/completed resulting in a PayPal transaction.

Normally in onApprove you do something like call actions.capture() , so if that is successful (and only if that is successful) you would want to trigger your PHP code. A more secure implementation would be to call your PHP code and have it do a v2/orders capture API call on the server side, but that is up to you. Here is a demo of such a server-side integration pattern: https://developer.paypal.com/demo/checkout/#/pattern/server

Alternatively, you could also try defining an onComplete function to call your PHP code.
