# Generate Code

> Generate a unique random code in a ChatbotX Flow for vouchers, tickets, order references, and other customer records.

**Generate Code** creates a unique random string or number inside a Flow. Use it when each customer needs a reference that is different from every other customer, such as a voucher code, event ticket, or order ID.

The Flow can use the generated result in a later message, a Custom Field, or another Action.

## Add Generate Code to a Flow

<Steps>
  <Step title="Open the Flow">
    Open the Flow that needs to create a unique code.
  </Step>

  <Step title="Add a Perform Action node">

## Choose a code type

| Type                    | Description                                    |
| ----------------------- | ---------------------------------------------- |
| **Numeric Length**      | Generates a random sequence of decimal digits. |
| **Numeric Value**       | Generates a random integer.                    |
| **Alphanumeric Length** | Generates random characters.                   |

Select the **Custom Field** where ChatbotX should save the generated result. Use **Add** when you need a new Custom Field.

## Example: send a check-in code

When a customer registers for an event, the Flow runs **Generate Code** and saves the result. The next message sends the code to the customer as their check-in reference.

<Note>
  Generate the code before the message that displays it. This ensures the Flow has a value ready to insert for the customer.
