Use `${{ .workflowInputs.variableName }}` to pass dynamic values at runtime in endpoint URLs and other input fields.

**What this approach does:**

-   Accept dynamic input values when workflow is triggered
-   Reference input values using template syntax throughout workflow steps
-   Enable workflow reusability with different parameters

## Example

```json
  {
    "inputs": [
      {
        "key": "urlParams",
        "value": "{\"filter\": \"active\"}"
      },
      {
        "key": "headers",
        "value": "{\"Api-Key\": \"your-api-key\"}"
      }
    ]
  }
```
