A number of sellers were alarmed when they saw a "Configure APIs" notification when they signed in to PayPal. The good news is you can safely ignore that message.
If you're curious as to why the message appears, read on.
By default, PayPal accounts are set up to accept Express Checkout payments. In other words, you don't need to do anything to receive Express Checkout payments. We confirmed this with PayPal when we first discussed moving to Express Checkout and along the way as we built the new Checkout.
A few days ago, some Etsy sellers started to see a "Configure APIs" notification when they signed in to their PayPal account. Our understanding is that this notification appears if you have received multiple Express Checkout payments from Etsy. The purpose of the notification seems to be to let you know that you're receiving Express Checkout payments. The notification takes you to a page with two options:
1. Yes, grant API permissions to my Etsy (API username: PayPal_API_api1.etsy.com) online store.
2. No thanks – I'll configure API permissions later.
If you select Yes, you're simply granting Etsy explicit permission to send you Express Checkout payments.
If you select "No thanks – I'll configure API permissions later", it's as if you did nothing. It simply means that you're not setting permissions specific to Etsy. You will continue to receive Express Checkout payments because the default PayPal setting is to accept all Express Checkout payments.
If you select Yes and then remove API permission for the Etsy API username, it's as if you selected No thanks. You no longer have permissions specific to Etsy, and you will continue to receive Express Checkout payments because that's the default PayPal setting.
Our understanding is that the only way you could block receiving Express Checkout payments is if you changed the Express Checkout setting, under API Access, to "Block payments from uncredentialed shopping carts (blocks payments from online stores or shopping carts until you set up API permissions)."
The bottom line is you can ignore this notification, and you don't need to do anything to receive Express Checkout payments from Etsy.
