On some occasions you may want to run some tests before deploying a campaign to the general public. Having Development Mode turned on will allow you to do that. All campaigns by default will only allow you to use the embed code on the original website you entered when setting it up. This feature allows you to be able to test your creatives using any domain name, IP address or localhost.
To turn on this feature go to the campaign you want to set this up for and select Settings to the right of the campaign name. Next switch the button for Development Mode to Yes.
Please Note: Development mode will only stay active for a period of 1 hour at a time.
