note Quick Start Guide

It is also possible to pass Custom Parameters via API requests.


Lets assume that it is needed to request an ad in the XML format. To accomplish that:

  1. Copy the Request URL from the API tab of the Invocation Codes pane. For this example it will be:
  2. http://n101.epom.com/ads-api-v3
  3. Add the placeholders for parameters to the Request URL:
  4. http://n101.epom.com/ads-api-v3?key=&format=
  5. Copy and paste the corresponding values from the API tab of the Invocation Codes pane:
  6. http://n101.epom.com/ads-api-v3?key=6d83a03ab653bbe2d51d05c95fad88a5&format=XML
  7. Paste the Request URL with parameters into the address field of your Web Browser and press Enter.

This should return you the information regarding the Banners linked to the Placement in question in the XML format:

200 OK

It consists of the following sections:

  • creative - path to the Banner creative.
  • beacon - Impression tracking URL.
  • click - Click tracking URL.
  • code - Banner source code.

To check if there is a Banner that can be served, open the Developer tools in your Web Browser and switch to the Network tab. The response code (Status) should be 200 OK:

200 OK

For another banner types, the responses would be:

HTML response sample:

<a href="http://foo.bar/landing" target="_blank"> <img border="0" alt="foo.bar" src="http://foo.bar/img.png" width="300" height="50"></a>

JSONP response sample:

jQuery172021720809857884849_1337079958141({"code":"<a href=\"http:\/\/foo.bar\/landing\" target=\"_blank\">\n <img border=\"0\" alt=\"foo.bar\" src=\"http:\/\/foo.bar\/img.png\" width=\"300\" height=\"50\">\n <\/a>"});

JSON response sample:

{ "success":true,
"code":"<a href=\"http://landing.url/landing\" target=\"_blank\"><img border=\"0\" alt=\"\" src=\"http://path.to.creative/320x50.gif\" width=\"320\" height=\"50\"></a><img src=\"http://impression.beacon/impression.gif\"/>" }

When there is no Banner that can be displayed, the response code would be the same (200 OK), but a No-impression beacon will be served instead of banner markup.

HTML No-impression response sample:

<script type="text/javascript">
new Image().src = "http://impression.beacon/no_impression.gif";

JSONP No-impression response sample:

"code":"<script type=\"text\/javascript\">
new Image().src = "http:\/\/impression.beacon\/no_impression.gif\"

JSON No-impression response sample:

"code":"<script type="text/javascript">
new Image().src = http://impression.beacon/no_impression.gif";

XML No-impression response sample:

<response><success>false</success><code><script type="text/javascript">new
Image().src = "http://impression.beacon/no_impression.gif";</script></code></response>
