When downloading PayPal payment history as a CSV, the data contains columns labeled, "Option 1 Name," "Option 1 Value," "Option 2 Name," and "Option 2 Value."
My application submits payments to PayPal through the NVP API (at endpoint https://api-3t.paypal.com/nvp), using the DoDirectPayment method.
Using this API, is there a way to submit some name-value pairs that will allow me to insert ad-hoc values into the "Option 1 Name," "Option 1 Value," columns mentioned above?
Sources I've consulted:
I believe the documentation is here: https://developer.paypal.com/docs/classic/api/merchant/DoDirectPayment_API_Operation_NVP/
Things I've tried:
I've tried adding the following various name-value pairs to the request, an odd assortment to say the least. It's an odd assortment, I admit, as I was trying just about anything that might work from various online sources, most of them probably either outdated or for another Paypal API.
$params['option_name0'] = "foo";
$params['option_selection0'] = "bar";
$params['option_name_1'] = "foo";
$params['option_selection_1'] = "bar";
$params['on1'] = "foo";
$params['os1'] = "bar";
$params['on0'] = "foo";
$params['os0'] = "bar";
$params['on0_1'] = "foo";
$params['os0_1'] = "bar";
$params['option_select0'] = "foo";
$params['option_amount0'] = "bar";
$params['option_select1'] = "foo";
$params['option_amount1'] = "bar";
$params['L_NAME0'] = "L_NAME0";
$params['L_DESC0'] = "bar";
$params['L_NAME1'] = "L_NAME1";
$params['L_DESC1'] = "bar";
None of the above have succeeded in putting any values into these columns. So is this possible at all? And if not, what could these columns possibly be for?
