Sending customers orderID with transaction --> REST API

[bidmore]

Hello,

I'm looking for an answer to my question:

If we (Webshop) connect to PayPal through API. Can I send the ID of the customers order with the transaction and will the PayPal API pick up this data so it can be presented to the accounts owner?

Hi, what you could do is passing a variable with the value of the orderID. The variable is:

1) for REST APIs, "custom" that must be passed inside the transaction object

2) for classic NVP APIs, "PAYMENTREQUEST_n_CUSTOM", to pass into the SetExpressCheckout API call

Once you pass this variable you will have the value available in your integration.
