### Adjusting Permissions

An Admin of your NationBuilder account will need to follow these steps:

1. **Go to Settings**: Click on `Settings` in the main menu of NationBuilder.
2. **Select Nation Defaults**: Within Settings, find and select `Nation Defaults`.
3. **Edit Permission Sets**: Navigate to `Permission Sets` and edit the relevant set.
4. **Enable Key Permissions**:
   * Ensure the `API` option is checked.
   * Activate the "Sign into apps" permission.
   * Leave other permissions unchanged unless otherwise needed.

By enabling these permissions, your account should be all set to access and use FieldEdge effectively.
