# Apex RelayDynamicInput

This resource is used to hold a single dynamic input name and value pair. This resource is used for both Relay dynamic **input_** and **ext_** definitions. You will need to create a single flow resource for each individual dynamic input that is required.

> [!WARNING]
> IMPORTANT
> 
> If you are defining a Relay dynamic **input_** resource, make sure your Relay CSM has configured your Relay client with the same input name otherwise it can’t be used within a Relay experience. No additional configuration is required, on the Relay side, when defining dynamic **ext_** resources.

> [!NOTE]
> NOTE
> 
> If you will just be extracting field values from the current **$Record** then it might be easier to use the dynamic input field name convention. See: [Relay Dynamic Inputs](/v1/docs/relay-dynamic-inputs)

## Assign Values to the RelayDynamicInput Resource

The **RelayDynamicInput** resource has two fields that need to be set with a Flow **Assignment** element.

| FIELD | DESCRIPTION |

Every client will have a Relay Client Success Manager (CSM) assigned to the account. This person will be your primary point of contact for the duration of your engagement with Relay Network.
