We are collecting dues for a family reunion. Adult "dues" ( let's call them tickets to make it easier ) are $100, kids are $75.

I have a simple form that asks the family name, how many adult tickets, how many kid tickets.

Can someone show me how to send this information to PayPal for processing, please?

Our site is on a PHP server, so a PHP sample would be great, or Javascript.

Thank you

How to check whether my Magento  CE 1.9.3.3 is already compliant in regards to PayPal security changes on the following?

• IPN Verification Postback to HTTPS
• Discontinue Use of GET Method for Classic NVP/SOAP APIs

If it is not compliant, what should I change to continue using PayPal?

Here is the PayPal link:

In Magento CE 1.9, which are the tables that payment configuration and PayPal configuration?

I'm using PayPal SDK to create instant payment.

The code is below

PayPal.Api.Payment createdPayment = PreparePaymentModel(returnUrl, 
    model.CancelUrl, model.PaymentDetails, model.PaymentMethod, 
    model.PaymentIntent, model.CreditCardId);

    // Create a payment using a APIContext
    createdPayment = createdPayment.Create(apiContext);

Getting HttpException sometimes with PayPal_debug_id.

Nowadays, PayPal is one of the most widespread payment systems all over the world. It makes internet payments easy and quite fast. Even online gaming providers which have the premium content option or gaming staff for real money are accepting PayPal in their products. What is more surprising, even online casinos like ones from this list http://free-slots-no-download.com/paypal/ allow you to make payments with it from your account. So I am interested in your opinion about it. How do you think, why it is so popular?

Running the following CURL command:

I am faced with an error to do with the  SSL certificate:

curl: (60) SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). The default
 bundle is named curl-ca-bundle.crt; you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.
[#### ~]$ curl --tlsv1.2 https://tlstest.paypal.com/
curl: option --tlsv1.2: is unknown
curl: try 'curl --help' for more information
[#### ~]$ curl --tlsv1 https://tlstest.paypal.com/
curl: (60) SSL certificate problem, verify that the CA cert is OK. Details:

I have a client who's selling tangible goods (ie: food products) online using WordPress & Woocommerce and who's based out of New Hampshire in the US, .. where there's no sales tax.  

Should I be setting up any kinds of special tax tables to ensure that customers are paying sales tax based on whatever US state they're having the merchandise shipped to? In other words, .. if someone from AZ purchases something from the NH business owner and has it shipped to them in AZ .. does the extra 8.1% sales tax apply in this situation?  Or not?

If the extra state specific sales tax DOES apply .. then what's the most efficient way for me to set that up within WooCommerce?

Thanks,
- Yvan
