 * Hi guys,
 * I have been trying to setup my paypal express but when I save the credentials
   it shows this notification There is a problem with PayPal. **Your API credentials
   may be incorrect. Please update your API credentials.** [Learn more.](https://docs.woocommerce.com/document/subscriptions-canceled-suspended-paypal/#section-2).
 * I have checked the credentials over and over and with PayPal integration peps
   as well and they are correct. The API is signature not certificate… I have a 
   woocommerce membership and woocomerce subscription plugins both plugins are up
   to date and work perfectly fine with stripe but can’t seem to get it to work 
   with Paaypal express. Do I have to get a paypal Pro? Thank you in advance for
   all your help 😀

 * Expres Checkout is what you want with our plugin. It replaces Standard and gives
   you a lot more options and flexibility. It will also increase conversion rates
   on your site, so I wouldn’t recommend going back to standard.
 * You just need to make sure you get your API credentials entered correctly. [Click here](https://www.paypal.com/us/cgi-bin/webscr?cmd=_login-api-run)
   and log in with your PayPal account. If you’re asked about Certificate or Signature
   make sure to choose Signature. It will return a username, password, and signature
   value. Those are what you need to copy and paste into the plugin fields.

 * I know that, the credentials are right.
 * The problem is that I cannot use ExpressCheckout because I am not a bussiness
   so I did not able to give the needed informations in Paypal to do so.
 * I tried to unninstall your plugin to return to the only mode that I am able to
   use Paypal (Standard) and it seems that your plugin change something in other
   plugin (WooCommerce or Woocomerce Subscriprion) that set the POSTing “[METHOD]
   => SetExpressCheckout” , instead of the default STANDARD one.
 * Do you know how can I go back to Standard again?

 * So you completely removed our plugin but new subscriptions are still showing 
   up as SetExpressCheckout??? That doesn’t make sense. The only way SEC would be
   showing up is if the Woo Subscriptions plugin was seeing an Express Checkout 
   gateway enabled within it. Are you sure you don’t still have some other Express
   Checkout plugin enabled?
 * Side note, what are you setting up Subscriptions for if you are not a business,
   out of curiosity?

 * In Brazil you can work with or without a “CNPJ”, and this number Paypal requires
   to work with Express Checkout.
 * Well, so I will try to figure out, but it appears after install your plugin. 
   If you have any input will be awesome.
 * If I find the answer I will update you.
