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 API key (to view the API key, click here).
