## Setup Guide

You'll need the following information to set up your Trello App with Paragon Connect:

* API Key
* API Secret
* Scopes Requested

### Generate a Trello API Key and API Secret

1. Log in to Trello. If you don't have an account, you can create one [here](https://trello.com/).

2. Access the [Power-Up Admin Portal](https://trello.com/power-ups/admin). If you haven't created a Power-Up yet, click on "New" to create one.

3. Within your Power-Up's settings, go to the **API Key** tab.

4. Your **API Secret** will be displayed in the same section.

### Add your Trello app to Paragon

1. Select Trello from the **Integrations Catalog**.

2. Under **Integrations > Connected Integrations > Trello >** **Settings**, fill out your credentials in their respective sections:

* **API Key:** Found under API Key > API Key.
* **API Secret:** Found under API Key > API Secret.
* **Permissions:** Select the scopes you've requested for your application. For a list of recommended scopes, please view this integration within your Paragon dashboard. [View dashboard.](https://dashboard.useparagon.com)

Press the purple "**Save Changes**" button to save your credentials.

<Info>
  **Note:** Leaving the API Key and API Secret blank will use Paragon development keys.

## Connecting to Trello

Once your users have connected their Trello account, you can use the Paragon SDK to access the Trello API on behalf of connected users.

See the Trello [REST API documentation](https://developer.atlassian.com/cloud/trello/rest/) for their full API reference.

Any Trello API endpoints can be accessed with the Paragon SDK as shown in this example

```js JavaScript theme={null}
// You can find your project ID in the Overview tab of any Integration.

// Authenticate the user
paragon.authenticate(<ProjectID>, <Paragon User Token>);

// Get a board
await paragon.request("trello", "/boards/<Board ID>", {
  method: “GET”,
});

// Create a new card
await paragon.request("trello", "/cards",
  method: “POST”,
  body: {
    idList: “<List ID>”,
    name: “New task”,
    desc: “Integrate all productivity apps using Paragon”
  }
});
```

## Building Trello workflows

Once your Trello account is connected, you can add steps to perform the following actions:

* Search Cards
* Get Cards in Board
* Create Card
* Update Card
* Delete Card
* Get Lists in Board
* Search Boards

You can also use the [Trello Request](/workflows/requests#making-integration-requests) step to access any of Trello's API endpoints without the authentication piece.

When using Trello, you can reference data from previous steps by typing `{{` to invoke the variable menu.

## Using Webhook Triggers

Webhook triggers can be used to run workflows based on events in your users' Trello account. For example, you might want to trigger a workflow whenever Cards are updated to sync your users' Trello Cards to your application in real-time.
