I am using Paypal Express Checkout payment gateway. When you checkout using express checkout, it will redirect to paypal page. On the top left I need to display my store logo instead of text.
So far I have figured out that the API used is SetExpressCheckout API Operation (NVP)
In this there is a field named HDRIMG which sets the logo. In core_config_data table this can be seen with path paypal/style/paypal_hdrimg. If the logo URL is set from DB then it shows the logo on paypal page, but I need to set it from
public function start($returnUrl, $cancelUrl)
Any help is appreciated.
