Invocation Codes

The Invocation Codes pane includes all the code types available for the current Placement Type:

Standard Site Placement: Universal JS, Iframe (Sync and Async), Simple Iframe, JS (Sync and Async), Direct URL, API
Non-Standard Site Placement: Universal JS, JS (Sync and Async), Direct URL, API
Mobile Site Placement: Universal JS, Iframe (Sync and Async), JS (Sync and Async), PHP, Direct URL, API
Video Placement: Vast 2.0; Vast 3.0 tags and OVA configs

It also contains the Settings section, where you can save the Channel, Custom Parameter and/or 3rd Party Click Tracking Url values for further usage. This will allow you to apply the frequently used Channels, Custom Parameters and/or 3rd Party Click Tracking Urls to the Invocation Codes of any Placements in your network in a matter of seconds instead of manually inserting those for each and every Placement.

Invocation Codes Specifics

For Universal JS code there are two additional options: Domain which allows to select ad serving domain from the list, and Ad Wrapper (for Standard Site Placement invocation codes only). The values are: Without Wrapper, Friendly Frame (default), Sandboxed Frame, No-redirect Frame.
A Fit container option is used for Universal JS invocation codes at Non-standard and Mobile placements. For outstream ad formats (interstitial, footerbar, etc.) Friendly Frame Ad Wrapper should be used with Fit container inactive. For banner ad formats Friendly Frame Ad Wrapper should be used with activated Fit container option. It allows banner to "fit" 100% of the container in which the code is executed.
Typically, elements of the web-pages are executed sequentially. If the Sync (synchronous) code - either iframe or JS - is used, it won't be requested until all the preceding elements have been loaded.
Asynchronous (Async) Codes provide an option to load elements in an order that is different from the way it has been organized in the web-page markup.
It is not recommended to use Sync and Async codes on the same web-page in order to avoid conflicts.
Async codes consists of two parts - HEAD and BODY. The HEAD tag can be placed anywhere on the page. BODY is a placeholder for the ad and should be placed at the spot where you would like your ad to be displayed.
The default size of the iframe Invocation Codes for Mobile Placements is 320x50. If the Ad Unit has a different size, the corresponding values should be inserted to the supp_width and supp_height parameters of the Invocation Codes.
All the Invocation Codes support the Cache Buster mechanism which prevents browsers from reusing an ad that has already been seen and cached previously.

Below you can find examples of different Invocation Codes along with the explanations of their structure.

API

&clientIp=112.12.23.33&requestUrl=http://epom.com&format=html

You can serve any types of ads by forming HTTP requests and sending them. The API response can have an HTML, JSONP, JSON or XML format.

Using Multiple JS Async Invocation Codes on one page

To place two Async Invocation Codes on the same page they must be combined together:

Copy the Configuration section from the HEAD of the Invocation Code.:

Paste this section to the HEAD of the second Invocation Code.

Insert the Division Units (<div> tags) from the BODY sections of Invocation Codes in the body of the web-page at the spots where you'd like your ads to be displayed.

❗️
Warning!
The Division Unit Identifiers should be different in order for both the ads to be displayed. Therefore, when using the same tag on the page multiple times, add any symbol to the supp_target_id and the corresponding Div IDs, i.e.:
<supp_target_id:"epom-90753ccb2860340d85e7ed09cda4c4f8X-300x250">
<div id="epom-90753ccb2860340d85e7ed09cda4c4f8X-300x250">

As a result, your Web page will be structured in the following way:

&lt;!DOCTYPE html&gt;<br />
&lt;html&gt;<br />
&lt;head&gt;<br />
&lt;title&gt;Test page&lt;/title&gt;<br />
