# Trello authentication

> Connect UiPath to Trello using OAuth 2.0 with your Trello API key and secret.

## Prerequisites

To create a connection, you need the following credentials:

* Client ID (corresponds to your API key)
* Client Secret

You can retrieve your API key and secret from your [Trello account](https://trello.com/app-key).

To learn more about OAuth 2.0 authentication for Trello, refer to the [Trello authentication documentation](https://developer.atlassian.com/cloud/trello/guides/rest-api/authorization/#authorizing-a-client).

## Add the Trello connection

1. Select Orchestrator from the product launcher.
2. Select a folder, and then navigate to the **Connections** tab.
3. Select **Add connection**.
4. To open the connection creation page, select the connector from the list. You can use the search bar to find the connector.
5. Enter the required credentials: Client ID and Client secret.

   Where available, select the menu next to a field and choose **Use credential asset** or **Use Orchestrator asset** to reference an Orchestrator asset instead of entering the value directly. For more information, see [Use credential assets for connections](credential-store-connections.md).
6. Select **Connect**.
7. Next, you are asked to authorize the UiPath application access to your account. Select **Allow**.
