# Get started

> Configure and deploy the Smarty Connector with Grand Central

Complete the following prerequisites and configuration to start using the Smarty Connector.

## Prerequisites

Before you begin, make sure that the following requirements are met:

* You have completed the steps in the [Get started](/connectors/getting-started).
* You have an active contract with Smarty and your own accounts and credentials set for Smarty services.

## Configuration

To configure your connector, follow these steps:

1. Set your APIM subscription key in the header as follows:
   * Key: `api-key`
   * Value: `<your subscription key>`

2. Request the Grand Central team to set up a connection with Smarty, and provide the following details for OAuth token generation:
   * `smarty-us-license`
   * `smarty-us-metadata-license`
   * `smarty-int-license`
   * `smarty-auth-id`
   * `smarty-auth-token`

3. Configure the Smarty `baseURL` in the `gc-applications-live` repository in the connector's `values.yaml` file:

   ```properties theme={"system"}
   smarty.int.base.url = //SMARTY environment base URL for International Address AutoComplete
   smarty.us.base.url = //SMARTY environment base URL for US Address AutoComplete
   smarty.us.metadata.url = //SMARTY environment base URL for US Address Validation
   ```

4. Verify the connector's `values.yaml` file location in the repository:

   ```
   ├── iPaaS
   └── azure/runtimes
       ├── dev
       └── test
           └── values
               └── gc-smarty
                   └── location-data-management-v1.values.yaml
   ```

## Test your integration

To access the Location Data Management Unified API, include your Grand Central subscription key in the request header. If you don't have a key, contact the Grand Central team to have one provisioned.

| Key       | Value                     |
| :-------- | :------------------------ |
| `api-key` | `<your_subscription_key>` |

Test the API using the [Postman collection](https://github.com/bb-ecos-ecos/grandcentral-documentation/blob/main/Postman-Collection/GC%20Location%20Data%20Management%20-Unitfied%20Spec.postman_collection.json).

## Troubleshooting

If your connector isn't responding as expected, check these common scenarios.

<AccordionGroup>
  <Accordion icon="lock" title="5xx: internal server error or core system down">
    **Cause:** The Grand Central gateway cannot establish a handshake with the Smarty endpoint. This typically indicates an upstream service outage at Smarty or a network routing failure.

    **Solution:** Verify the operational status of the Smarty environment with Smarty. If the service is operational, contact the [Grand Central team](mailto:gc_support@backbase.com).
  </Accordion>

  <Accordion icon="wifi-slash" title="5xx: timeout or sockettimeoutexception">
    **Cause:** The request to Smarty exceeded the configured timeout threshold. This can occur during high load or network latency issues.

    **Solution:** Verify the operational status of the Smarty environment with Smarty. If the service is operational, contact the [Grand Central team](mailto:gc_support@backbase.com) to review timeout configurations.
  </Accordion>

  <Accordion icon="key" title="Invalid authentication">
    **Cause:** The credentials provided during setup are incorrect.

    **Solution:** Verify your credentials with Smarty and contact the Grand Central team to update the connection.
  </Accordion>

  <Accordion icon="gauge-high" title="429: rate limit exceeded">
    **Cause:** The number of incoming requests exceeded the defined threshold for your subscription tier. This response protects the stability of the Grand Central and partner infrastructure.

    **Solution:** Review your application's request patterns to identify unexpected spikes. If you require higher throughput, contact the Grand Central team to request an adjustment to your APIM rate limit policy.
