I'm trying to use the PayPal-PHP-SDK to integrate PayPal with a custom built WordPress eCommerce theme and I'm getting a an error:
Got Http response code 400 when accessing
https://api.paypal.com/v1/payments/payment/..
.
This error only appears when I which to live, it works completely fine on sandbox mode.
On the client side I'm using checkout.js and redirecting it to the PHP file where I'm trying to use the the PayPal-PHP-SDK to execute the payment and I get the error where the code reads:
$result = $payment->execute($execution, $apiContext);
Below is a sample code I am using
JavaScript
paypal.Button.render({
env: 'production',
client: {
sandbox: 'sandbox_id',
production: 'production_id'
locale: 'en_US',
style: {
color: 'blue',
size: 'responsive',
commit: true,
payment: function (data, actions) {
return actions.payment.create({
payment: {

The above code is part of an old code that was on the website, I'm just trying to make it work. It was working fine until we changed the Client and Secret ID. The payment is being created fine but the issue comes when I execute the payment

I'm definitely doing something wrong with this.
Hard to guess at what precisely is wrong with the execute call without seeing the full API response body and headers, including a PayPal-Debug-ID
400 errors are usually a wrong credential problem, or credentials paired with the wrong environment, but that is less likely if your payment creation and oauth2 calls are working okay
The more important question is why are you using an deprecated V1 SDK, at all, which is no longer maintained? You should completely change your integration to the current V2 PHP SDK, documented here: https://developer.paypal.com/docs/api/rest-sdks/
The current best front-end experience to pair it with is https://developer.paypal.com/demo/checkout/#/pattern/server
