# Personalization of OSM Content

> Personalize On-site Messaging content in MoEngage using user attributes, events, catalogs, and content APIs. Add dynamic content with the @ symbol.

You can personalize content in your On-Site Messaging (OSM) campaigns. Use the **@** symbol to add dynamic content to text and images.

You can personalize campaign content by using the following data types:

* User Attributes
* User Events
* Product Catalogs
* Content APIs
* Content Blocks
* Auxiliary Data

For more information about these personalization options, see:

* [MoEngage Templating Language (Jinja)](/user-guide/campaigns-and-channels/getting-started/message-personalization/jinja-templating-language)
* [Derived Events & Attributes](/user-guide/data/event-data/derived-events-and-attributes)
* [Product Catalogs](/user-guide/content/recommendations/prerequisites/catalogs)
* [Content APIs](/user-guide/campaigns-and-channels/getting-started/campaign-content/content-apis)
* [Content Blocks](/user-guide/content/content-blocks/content-blocks)
* [Auxiliary Data](/user-guide/data/imports/file-based-imports/auxiliary-data)

To personalize content in your OSM campaign, follow these steps:

1. In step 2 of campaign creation, click the **text box** or the **Image Property URL**.
2. To personalize text, press **@** anywhere within the **text area**. The Data Personalization pop-up window appears.

4. In the Data Personalization pop-up, do one of the following:
   1. Select **Data Personalization**.
      1. From the drop-down list, select one of the following data types:
         * **User Attributes**
         * **Product Catalogs**
         * **Content API**
           1. Modify the values of the Content API parameters. For more information, refer [here](/user-guide/campaigns-and-channels/getting-started/campaign-content/content-apis).
      2. Select one of the following fallback options:
         * **No Fallback**: No alternate content is displayed if personalization fails.
         * **Do not send In-App**: In-App messages are not sent if personalization fails.
         * **Replace Text**: Type or paste the text to display if personalization fails.
   2. Select **Content Block**.
      1. Select the **content block** to insert.
      2. Click **Insert only the content of the content block**.

         <Info>
           This option inserts only the content, which is disconnected from the original content block. Any future updates to the original content block are not reflected in the inserted content.
         </Info>
5. Edit your Jinja code in the **text area** after selecting the attribute or content block.
6. Click **Done**.
7. To edit the Jinja code again, click the personalization in the **text box**.

   <Warning>
     Avoid selecting another attribute from the drop-down list. Doing so will replace the entire Jinja code in the text box.
   </Warning>

<Info>
  Ensure that custom attributes do not have the same names as MoEngage's standard attributes. If a custom attribute and a standard attribute having the same name are used for personalization, it could result in incorrect personalization.
