I propose to buy I am asked for the promo code I do not know it help me.
You do not have a Promo Code. Simply leave that field empty and don't click on "Apply" next to it.
As Petra noted, you can buy Connects without a Promo code by just leaving the field empty and clicking on Buy Connects at the bottom. You will also need to add a Billing Method to your account in order to purchase Connects. You can learn about the available Billing Methods here.

Yes you can. Leave it blank and then scroll down without clicking on "Apply" and click on the green "Buy Connects" button.
We don't have any discount codes or promos available at the moment nor there's any qualification that would award one. Periodically, offers are sent by Upwork via email, at events, and through partnerships. To ensure you get the marketing emails, please submit the following form and we’ll add you to the list!
