- Vertoz currently supports Open RTB Protocol 2.3.1. IAB documentation for OpenRTB 2.3.1 implementation can be found here.
Limitations imposed on the OpenRTB specs
- CPM campaigns only.
- Currency: USD only.
- Creative (ad markup) shall be sent by the DSP directly within the bid response.
- One bid per request only. Multiple bid/seat responses won’t be accepted.
- Campaign formats (ad types): image, VAST video.
- Vertoz currently supports Vast 2.0 & 3.0.
Bid response compliance
The bid response must at all times (regardless of test or live mode) fulfill following condition
- Compliance with the OpenRTB specs.
- The ad returned must correspond with the requested ad type. E.g. if the request only allows an image banner, you may not return a Rich Media ad, etc., see the OpenRTB specs regarding the attributes Banner.btype and Banner.mimes.
- The size of the returned ad needs to match the requested width & height, or at least the aspect ratio, as specified above.
- The bid response should contain the following parameters which are optional as per the official OpenRTB documentation, but required by Vertoz:
- nurl – Win notice URL that is used to notify the DSP each time when an auction was won.
- crid – Creative ID for reporting content issues or defects. This could also be used as a reference to a creative ID that is posted within an exchange.
- adomain – An advertiser’s primary or top-level domain for advertiser checking. Please Note: A bid will be rejected in case any domain(s) in this parameter matches the domain(s) passed inside of the badv parameter of the bid request.
- iurl – Sample image URL (without cache busting) for content checking.
Checkpoints for DSP Integration
DSP Endpoint url
Our Servers are located in North Virginia and Singapore. The DSP endpoints should reside in these or nearby regions for reducing network latency. The DSP should mail us their endpoint details at email@example.com. Please send the DSP endpoint url by email. Example of DSP endpoint url: http://xyz.abc.com/?rtb=1234
You may send different urls for test and production purposes.
Vertoz Ad exchange gives demand sources 200ms (roundtrip time on bid request) to respond to bid requests.
Send us your Reporting API
Vertoz would need DSP Reporting API for reconciliation of auction wins, impression and revenue numbers. Vertoz would also create an account for the DSP user on our platform to check the relevant metrics recorded by us.
Once the integration of the DSP endpoint is completed, and the traffic produces data, we will monitor and reconcile key metrics and check for discrepancies if any.
