The API key is needed to manage proxies programmatically: order, renew, and export lists without logging into the account.
Steps to follow
In the left menu, under "Settings", open the "Developer API" section.
"Developer API" section in the left menu.
Copy the key from the field — there is a copy button next to it.
If there is no key yet, click "Generate key".
"Developers API" section: field with the key and "Generate key" button. 1 — API key · 2 — "Generate key" · 3 — field for allowed IP addresses · 4 — "Submit"
Important. The "Generate key" button creates a new key, and the previous one stops working. All integrations using the old key will stop responding — update it consciously.
Important. Do not share the key with anyone: it provides full access to manage your orders.
To prevent the key from being used from an unauthorized address, restrict access by IP — how to do this is described in the article Restricting API Access by IP.
