If the brand that you have applied to is using PayPal to issue commissions (or "Earnings"), you will need to connect your PayPal account to your ambassador account in order to receive your earnings from the brand. To connect your PayPal, you can follow the steps below:
Log in to your ambassador account here
Navigate to Settings (⚙️ icon)
Go to "Payout Settings"
Click "Add PayPal Account" and type the correct email address associated with your PayPal account
Click the "Update Email" to connect your PayPal
Keep in mind that your commission becomes payable once it clears the brand's holding/processing period (shown as "Due" in your dashboard). From there, it's the brand who chooses when to actually issue the payout: there's no fixed schedule on Buzzbassador's end for exactly when a Due reward gets paid, it's simply a matter of when your brand manager sends it via PayPal (if applicable).
