Support banner

This page will accommodate the new adapter design, to support banner (display) type media, in our adapter

Changes are based on the prebid docs at: prebid docs

Current design takes the original GET request parameters, along with a new imp parameter (detailed structure below), and combines them into a single POST request with the following structure:

{
   // original GET parameters, including the data of the first adUnit
   "params": {   
               wrapper_type:
               wrapper_vendor:
                    ...
             }
   
   // array of all adUnits basic data
   "imp":    [{  
               id:
               h:
               w: 
                    ...
             }
             {
                    ...
             }]
}

Original GET request parameters:

{ 
    wrapper_type: 
    wrapper_vendor: 
    wrapper_version: 
    adapter_version:
    auction_start: 
    ad_unit_code: 
    tmax:
    width:
    height:
    publisher_id:
    floor_price: 
    ua: 
    bid_id: 
    bidder_request_id: 
    transaction_id:
    session_id:
    publisher_name: 
    site_domain:

New imp parameter structure (per AdUnit):

{
   id: // id - required 
   h: // height - optional
   w: // width - optional
   fp: // floor price - optional
   mt: // media type - required 
}

Phase 1

General structure change

• Add banner type to supported media type in spec
• Update endpoint to the new hb-multi
• Create the new imp object to send
• Change GET request to POST (and verify old behavior is not affected or destroyed)
• Find what's common between video and banner request and reuse data when building object
• Call endpoint only once for all adUnits, and not per-request as it is now (adapter was built for a single video request)

function specific

• isBidRequestValid - changed to support multiple bids
• isBidRequestValid - check if a different validation is needed compared to video
• buildRequests - check if a banner is built differently from video
• buildRequests - build an alternative for buildVideoRequest to receive and handle multiple adUnits, and return combined requests object

Phase 2

• Create a test object for the test endpoint
