This information will then be displayed in the [**Statistics**](/publishers/publisher-statistics.md) tab, in the **Sub IDs** sub-tab. ## Putting Sub IDs into your ad zone code Once you have clicked on **Create** in the **New Zone** screen, you will be presented with the code for your new ad zone. To use Sub IDs, add the **parameter** corresponding to the format you selected and the **number** you wish to use as Sub ID: | Parameter | Used in | | ---------- | ----------------------------------------------------------------------------------------------------------------------------- | | `sub` | Banners (iframe), Popunder (inline script), Direct Links, Email Clicks, In-Video Banner (VAST), In-Stream Video | | `ad_sub` | Popunder (remote script) | | `data-sub` | Banners (async), Sticky Banners, Outstream Video, Video Slider, In-Page Push, Instant Message, Native, Fullpage Interstitials | {% hint style="warning" %} Sub IDs should be a number between 1 and [**Int32**](https://docs.microsoft.com/en-us/dotnet/api/system.int32.maxvalue?view=net-5.0): Do not use zeroes at the beginning of Sub IDs. {% endhint %} ## Use in different ad zone formats Here is an extensive list of examples showing how to add the parameters needed to register Sub IDs. ### Asynchronous ad zones: Banners, Instant Messages, Sticky Banners and others Added `data-sub="123456789"` ```html ``` ### iFrame Added `&sub=123456` ```html ``` ### Popunder (inline) Added `"sub":"123456"` ```html ``` ### Popunder (remote) Added `ad_sub = "123456"` ```html ``` ### VAST ads (In-Stream and In-Video) Added `&sub=123456` ``` https://s.magsrv.com/v1/vast.php?idzone=1234567&sub=123456 ``` ### Push Notifications This format does not currently support the use of subids. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.exoclick.com/publishers/sites-and-zones/subids.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
