In order to update a campaign, you need to go to the campaign settings and make the modifications.
- Update geo targeting
- Fallback options
- Delivery domain
- Add / remove landing pages
- Add / remove offer links
When you're finished with the updates, don't forget to hit the Save button.
NB: You do not need to send a new campaign URL to your traffic source. The campaign URL remains the same.
NB: If you change the delivery tracking domain, you should send the new campaign URL to your traffic source. The old campaign URL will still work.
