Summarize the following:
Tap the PayPal app icon, which resembles a white "P" on a dark-blue background. This will open your PayPal page if you're logged in.  If prompted to log in, enter your email address and password and then tap Log In before proceeding. If you're using an iPhone or Android that has fingerprint ID, you may be prompted to scan it instead of entering your password. It's a tab at the bottom of the screen. You'll find this option near the top of the screen. Doing so brings up a menu of apps through which you can share your PayPal link. Tap the app you want to use to share the link. This will open the app with your link in the "Share" field. For example, if you want to send your PayPal link to a friend via a text message, you would tap your phone's Messages app icon. This would open the Messages app with your PayPal link in the text box. If you're sharing your link via a text or an email, for example, you'll need to enter the information for the contact (or group of contacts) to whom you're sending the link. If you're sharing the link on social media, skip this step. Once you've added any necessary information to the link, tap the Send or Post button to share the link.

Summary:
Open PayPal. Tap Request. Tap Share your link to get paid. Select an app. Enter the contact's information if necessary. Send or post your link.
