Authorization

Follow this guide to create a new Trello credential that will allow Nexla to authenticate to and exchange data with your Trello account.

Trello

Prerequisites

Before creating a Trello credential, you need to obtain your OAuth Consumer Key and Consumer Secret from your Trello account. Trello uses OAuth1 authentication for all API requests.

To obtain your Trello OAuth credentials, follow these steps:

1. Sign in to your Trello account using your administrator credentials.

2. Navigate to Power-Ups in your Trello account, or visit the Trello Developer Portal to access API key management.

3. In the Trello Developer Portal, navigate to API Keys or Developer API Keys to access your API key management.

4. If you don't have an API key yet, click Create API Key or Generate API Key to create a new API key.

5. Configure your API key settings:

   • Enter a name for the API key (e.g., "Nexla Integration")
   • Review and accept the Trello API Terms of Service
   • Click Create or Generate to create the API key

6. After the API key is created, you will see your API Key (Consumer Key) and API Secret (Consumer Secret). Copy both values immediately, as the API Secret may not be accessible again after you navigate away from the page.

7. Store both credentials securely, as you will need them to configure your Nexla credential. The API Secret is sensitive information and should be kept confidential.

The OAuth Consumer Key and Consumer Secret are used in the OAuth1 authentication flow to obtain access tokens. These tokens are then used to authenticate your requests to the Trello API. If your credentials are compromised, you should immediately revoke them in your Trello Developer Portal and generate new ones. For detailed information about obtaining OAuth credentials, API authentication, and available endpoints, refer to the Trello API documentation.

Create a Trello Credential

• To create a new Trello credential, after selecting the data source/destination type, click the Add Credential tile to open the Add New Credential overlay.

Credential Name & Description

1. Enter a name for the credential in the Credential Name field and a short, meaningful description in the Credential Description field.

   Resource descriptions are recommended but are not required. They should be used provide information about the resource purpose, data freshness, etc. that can help the owner and other users efficiently understand and utilize the resource.

OAuth1 Authentication

Trello uses OAuth1 authentication for all API requests. This method requires your OAuth Consumer Key and Consumer Secret to obtain access tokens through the OAuth1 flow.

2. The OAuth1 authentication flow will be initiated when you save the credential. During the OAuth flow, you will be redirected to Trello to authorize Nexla to access your Trello account.

3. After authorization, Nexla will automatically obtain and store the access tokens needed to authenticate API requests.

   Your Trello OAuth credentials (Consumer Key, Consumer Secret) can be found in the Trello Developer Portal under API Keys. The Consumer Secret is sensitive information and must be kept confidential.

   If your credentials are compromised, you should immediately revoke them in your Trello Developer Portal and generate new ones. The OAuth credentials provide access to your Trello account data and should be treated as sensitive information. Keep your credentials secure and do not share them publicly.

   For detailed information about obtaining OAuth credentials, API authentication, and available endpoints, see the Trello API documentation.

Save the Credential

1. Once all of the relevant steps in the above sections have been completed, click the Save button at the bottom of the overlay to save the configured credential.

2. The newly added credential will now appear in a tile on the Authenticate screen during data source/destination creation and can be selected for use with a new data source or destination.
