I am integrating PayPal with my platform in sandbox mode.
I want to rename "John Doe's Test Store" (pictured below) with the name of my platform.
I would also like to rename "John Doe's Test Store" in the second image below, with the name of my platform.
How can this be done?
To change the account's business name, log into that receiving sandbox Business account via https://www.sandbox.paypal.com/businessmanage/account/aboutBusiness
(If you need to change the sandbox account's password, do so from PayPal Developer)
To change the displayed business name for a particular transaction, set the v2/orders REST API application_context object's brand_name
parameter, or the old classic API's BRANDNAME parameter. This is mainly useful if you have multiple websites/storefronts going to one PayPal account.
