# Open Telekom Cloud

In order to integrate with Open Telecom Cloud, you must:

1. Create the account to access data in the Object Storage Service.
2. Give the account read access to the desired buckets by:
   * Creating a Custom Bucket Policy.
   * (Optional) If you have *Cross-origin resource sharing (CORS)* configured on your buckets, make sure that `*.encord.com` is given read access.
3. Create the integration.

## 1. Start Setting up the Integration

1. To create an Open Telekom Cloud integration, click the **+ Add integration** button in the [Integrations tab](/platform-documentation/General/annotate-data-integrations). Select *OTC*.

## 4. Configuring CORS

<Warning>
  If you use Infrastructure as Code tools like Terraform, they can overwrite your manual CORS settings. To prevent this, always include the correct CORS policy in your Terraform configuration file.
</Warning>

If your bucket has a configured CORS policy, make sure it permits access from `*.encord.com`.
