# Add rtc-config object to amp-ad units Once the placements creation and the GAM connexion are complete, you need to add the rtc-config object in your AMP tags. Real Time Config (RTC) is an AMP feature used for Header Bidding to make request calls to your SSPs. ## RTC setup Add the rtc-config object in your amp-ad unit, as in the following example: ``` ``` {% hint style="warning" %} Replace “ACCOUNT\_ID” and “TAG\_ID” with your unique IDs, which can be found in the “Sites management” tab: * ACCOUNT\_ID => Customer ID present at the top right of the UI. * TAG\_ID => Placement ID available on each line of the placements list. {% endhint %} {% hint style="warning" %} If you have configured a CMP, ensure to link the call to `amp-ad`unit to the user consent by adding the attribute `data-block-on-consent` in the ad unit. Integrate the following script in the`` : ``` ``` {% endhint %} {% hint style="info" %} The rtc-config code can be directly copied from the button on the top right of the website page "View rtc-config". {% endhint %} ## Cookie-sync setup You can add the cookie-sync functionality to help bidders identify the user and bid accordingly. While this step is optional, it is recommended to improve attractiveness to bidders. {% hint style="info" %} This process is GDPR compliant, as it will not be executed if a user doesn't provide consent. {% endhint %} Here is the script to add to your page: ``` ``` {% hint style="warning" %} **Implementation recommendations:** * The iframe must be either 600 px away from the top or not within the first 75% of the viewport when scrolled to the top. * To display a valid iframe, please add the `amp-iframe` component on your AMP page (if not already present). See required script below: ``` ``` :point\_right: See additional documentation here: . {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
