There are two ways to pay your next installment:
1. You will receive an email from the organizer. The email will have a big button "Make Payment". Just click on the button, sign in to your WeTravel account and you will be redirected to the payment page for your installments.
Then click on "Pay Installments" on the right side of the screen.
A pop-up appears where you can pay your next or all of the remaining installments.
Select a saved payment method or enter a new one and click "Confirm Payment"
Congrats, you just paid your next installment :)
