You can use the Bitly integration to replace the native Okt.to links that are created by Oktopost. This integration also functions with branded Bitly links.
Please note that there is no need to shorten the link in Bitly, as Oktopost will shorten it once it's published.
- Head over to App Settings → Integrations → Bitly.
- Enter your Bitly username and Access Token. To view the username, shown as login in Bitly, click here (You must be logged in to see this link). To generate the Access Token, from the link where you got your login, click User Settings, enter your Bitly password, and click the orange Generate Token button at the bottom of the screen.
