|Q1.||How can I assign banners to a line item?|
To assign banners for a line item you need to create a tag and specify all desired creatives. The tag itself won't be used as the banners will be served from one master tag, but it is still a necessary step.
|Q2.||I've reached the limit of 500 line items, what should I do?|
You can either create a new order (each order has a limit set to 500 line items) or create a brand new campaign within your agency account.
|Q3.||What is the difference between PlacementId and RTBActivityId?|
When creating line items, you will receive two IDs - RTBActivityId and PlacementId. The first one is used within the service (i.e. you will use it to get/update/delete a specified line item) while the second one is used when communicating with other related services (e.g. when creating a tag).
|Q4.||How can I set RTB campaign budget?|
RTB campaign budget can be set using RTB settings service.
