A merge field is a variable that references the value of a JSON node. For example, if a JSON node is `"FirstName": "John"`, then the merge field `%FirstName%` returns `John`. ![Managed Package app icon](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-xcloud-omnistudio_for_managed_packages-264-0-0-production-enus/aa2554ec-624a-4ee6-8da4-6435670e6e62/resources-global/_corporate/images/managedpackageicon.png) This information is for Omnistudio for Managed Packages. For Omnistudio on standard runtime, see [Omnistudio Help](https://help.salesforce.com/s/articleView?id=xcloud.os_omnistudio_standard.htm&language=en_US). Merge fields access data JSON using syntax to indicate to an Omniscript Element that a merge field is present. The syntax requires you to wrap a full JSON path with a percent sign on both ends. ![Note](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-xcloud-omnistudio_for_managed_packages-264-0-0-production-enus/aa2554ec-624a-4ee6-8da4-6435670e6e62/images/icon_note.png) Note Only certain element properties support merge fields. Text between two percent (%) signs in a Set Values formula or text field is treated as a merge field. To represent literal percent (%) signs, use the `$Vlocity.Percent` [environment variable](https://help.salesforce.com/s/articleView?id=xcloud.os_environment_variables_in_dataraptors_and_integration_procedures_1.htm&release=264.0.0&type=5 "For the managed package runtime, you can use environment variables to define Default Values and Filter Values, and in Formulas."). ## Common Use Cases (Managed Package) For the managed package runtime, learn about common use cases for accessing Omniscript data JSON with merge fields. ![Managed Package app icon](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-xcloud-omnistudio_for_managed_packages-264-0-0-production-enus/aa2554ec-624a-4ee6-8da4-6435670e6e62/resources-global/_corporate/images/managedpackageicon.png) This information is for Omnistudio for Managed Packages.

For Omnistudio on standard runtime, see [Omnistudio Help](https://help.salesforce.com/s/articleView?id=xcloud.os_omnistudio_standard.htm&language=en_US). 1. Locate the name of the JSON node in the Omniscript's data JSON. ![image](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-xcloud-omnistudio_for_managed_packages-264-0-0-production-enus/aa2554ec-624a-4ee6-8da4-6435670e6e62/omnistudio_for_managed_packages/images/omniscript_merge_data_json.png) 2. Enter the name of the JSON node and wrap the name in percentage signs to indicate it is a merge field. For example, a merge field accessing a JSON node named firstName must use the syntax %firstName%. ![image](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-xcloud-omnistudio_for_managed_packages-264-0-0-production-enus/aa2554ec-624a-4ee6-8da4-6435670e6e62/omnistudio_for_managed_packages/images/omniscript_merge_syntax.png) 3. Preview the Omniscript to ensure the Merge field works correctly. ![image](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-xcloud-omnistudio_for_managed_packages-264-0-0-production-enus/aa2554ec-624a-4ee6-8da4-6435670e6e62/omnistudio_for_managed_packages/images/omniscript_merge_field_result.png) ## Additional Syntax (Managed Package) For the managed package runtime, check out additional syntax examples for nested JSON. ![Managed Package app icon](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-xcloud-omnistudio_for_managed_packages-264-0-0-production-enus/aa2554ec-624a-4ee6-8da4-6435670e6e62/resources-global/_corporate/images/managedpackageicon.png) This information is for Omnistudio for Managed Packages.

JSON Node

Merge Field Syntax Example

 
"ContactInfo": {
    "FirstName": "John"
  }

Use a colon symbol : to access a nested JSON node.

%ContactInfo:FirstName%
 
"ParentObject": {
    "NumberMap": [
      1,
      2,
      3
    ]
  }

Use a colon symbol : to access nested JSON nodes and a pipe symbol | to access the index of the array that value.

%ParentObject:NumberMap|3%
 
 "ContactInfoStep": {
    "ContactInfoBlock": [
      {
        "FirstName": "John"
      },
      {
        "FirstName": "Adam"
      },
      {
        "FirstName": "Steve"
      }
    ]
  }

When a formula exists within a repeatable block, use |n to access the node in which the formula exists. Depending upon which node the formula exists in, it will return the correlating value. For more information, see Access to Data Within and Outside a Repeatable Block (Managed Package).

%ContactInfoStep:ContactInfoBlock|n:FirstName%
