# Check Credit Limit

## Purpose

Allows you to run a script when a credit check is performed for a quote. Typically this script makes a call to an enterprise resource planning (ERP) or other external system.

## Setup

Upload the script for **Check Credit Limit**.

For details about uploading and configuring Groovy scripts, read [Upload a Groovy script](/v1/docs/upload-a-groovy-script).

## Binding variables

In addition to the [common binding variables](/v1/docs/binding-variables), the following binding variables are available for this extension point.

| Variable name | Class | Description |
| --- | --- | --- |
| salesItemsTree | SalesItemsTree | Represents the quote. Contains functions you can use to query and modify the quote and its line items. |

For details about the classes listed in this table, including available methods, fields, and method signatures, read the [Zilliant Groovy API reference](/main/docs/groovy-api-reference).

## Expected output

The script should retrieve the values of one or more of the following fields from an ERP or other external system:

- Credit Limit
- Credit Exposure
- Credit Exceeded Amount

The script should then package and return the retrieved values as a **GroovyTable** variable. Additional data points may be returned and displayed with these values; however, the system does not process these additional data points.

## Script execution

The script uploaded for this extension point is run automatically when a user select **Credit Check** in a quote. Based on the returned **GroovyTable** variable, the system updates the values in one or more of the following fields:

- Credit Limit
- Credit Exposure
- Credit Exceeded Amount

Any other data returned by the **GroovyTable** variable appears in a pop-up window.
