Yes. In Tweetdeck version 0.34.2, support for custom URL shorteners was added. This means you can use Capture or your own custom domain that is powered by
Capture.
- In Tweetdeck, click on the Settings icon in the top right corner
- Click Services in the Settings area of Tweetdeck
- Choose "Other" from the dropdown list
- Enter your "URL Shortening Endpoint" into the field provided.
You can find your URL Shortening Endpoint by logging into
Capture, clicking on the Settings tab. If you are account owner you will then have to click on "Manage Your Personal Settings." (note: this same URL can be used in the Twitter for iPhone app to shorten your URLs there too!)
