Updating recurring profiles via NVP #10002: Authentication/Authorization Failed

[markoambrozic]

Hi,

I'm trying to implement a referral program on a clients website. This would allow customers to gain discount on existing recurring profiles when they invite friends.

I am having problems with the PayPal NVP API. When I try to update the billing and tax amount I get: PayPal gateway has rejected request. You do not have permissions to make this API call (#10002: Authentication/Authorization Failed).

Here is the request I am making:

https://api-3t.paypal.com/nvp
{
    "PROFILEID":"<specific profile id>",
    "AMT":"24.00",
    "TAXAMT":"2.28",
    "CURRENCYCODE":"EUR",
    "METHOD":"UpdateRecurringPaymentsProfile",
    "VERSION":"72.0",
    "BUTTONSOURCE":"Magento_Cart_Community"
}

Does anyone have any idea what could be wrong?

I would also like to add that all other Paypal functionality works fine (including creation, cancelation of recurring payments).
