Create Trello-Connected Business Apps in AppSheet



Connect to Trello Data via CData Connect Cloud in Google AppSheet and create custom business applications with real-time access to Trello data.

Google AppSheet is a no-code development platform for application software, enabling users to design mobile, tablet, and web applications. When combined with CData Connect Cloud, you gain immediate cloud-to-cloud access to Trello data for business applications. This article outlines the process of connecting to Trello using Connect Cloud and constructing a basic app from Trello data within AppSheet.

CData Connect Cloud offers a dedicated cloud-to-cloud interface for Trello, enabling the creation of reports directly from live Trello data within AppSheet, all without the need for data replication to a native database. When you design applications that interact with data, AppSheet formulates SQL queries to retrieve the required information. With its inherent optimized data processing capabilities, CData Connect Cloud efficiently channels all supported SQL operations, including filters and JOINs, directly to Trello. This leverages server-side processing to swiftly deliver the requested Trello data.

Configure Trello Connectivity for AppSheet

Connectivity to Trello from AppSheet is made possible through CData Connect Cloud. To work with Trello data from AppSheet, we start by creating and configuring a Trello connection.

  1. Log into Connect Cloud, click Connections and click Add Connection
  2. Select "Trello" from the Add Connection panel
  3. Enter the necessary authentication properties to connect to Trello.

    Trello uses token-based authentication to grant third-party applications access to their API. When a user has granted an application access to their data, the application is given a token that can be used to make requests to Trello's API.

    Trello's API can be accessed in 2 different ways. The first is using Trello's own Authorization Route, and the second is using OAuth1.0.

    • Authorization Route: At the moment of registration, Trello assigns an API key and Token to the account. See the Help documentation for information on how to connect via the Authorization route.
    • OAuth Route: Similar to using Authorization, OAuth creates an Application Id and Secret when you create your account. See the Help documentation for information on how to to connect.

  4. Click Create & Test
  5. Navigate to the Permissions tab in the Add Trello Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

  1. Click on your username at the top right of the Connect Cloud app and click User Profile.
  2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
  3. Give your PAT a name and click Create.
  4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured, you are ready to connect to Trello data from AppSheet.
