# How can I hide a field from the Delpha Bot conversation?

## How to Hide Fields in Delpha Bot During Duplicate Merges

When using the **Duplicate conversation in the Delpha Bot**, you might want to **hide technical or sensitive fields** from the end user to streamline the merge process and improve clarity.

This is especially useful for internal identifiers (e.g., external system IDs) that shouldn't be part of user-facing decision-making.

## Use Case Example: Hiding a Technical ID Field

If you have a custom field like `External_System_ID__c`, you likely don’t want it visible to users during the merge conversation.

Delpha makes it easy to hide this field from the bot UI while still applying a merge rule.

## How to Hide a Field in the Duplicate Conversation

### Step 1: Navigate to Merge Field Rules

1. Open the **Delpha Setup** app
2. Go to the **Duplicate Settings** tab
3. Select the **target object** (e.g., Contact, Lead, Account)
4. Scroll down to the **Merge Field Rules** section
5. Click **New Rule**

### Step 2: Configure the Field Rule

| Field             | Description                                                                            |
| ----------------- | -------------------------------------------------------------------------------------- |
| **Action**        | Choose `Customize` (used for single field customization)                               |
| **Visible**       | Set to `Off` to **hide the field** from the Delpha Bot interface                       |
| **Override Rule** | Choose the rule to determine how the field is populated (e.g., `Master and Not Empty`) |
| **Custom Value**  | Optionally set a **default value** that will overwrite the field after the merge       |

{% hint style="info" %}
When the Override Rule is set to Empty, the value will be reset after merge.
{% endhint %}

### Result

Once saved:

* The field is **not shown** to users in the Delpha Bot conversation
* Your **merge rule still applies** as configured
* The process becomes more **user-friendly and secure**
