Build Asana-Connected Apps in Mendix



Use CData Connect Cloud to create an OData feed for Asana Data and create custom apps in Mendix.

Mendix is a high-productivity app platform that allows you to build and maintain both mobile and web applications at-scale. When paired with CData Connect Cloud, Mendix provides instant, cloud-to-cloud access to Asana data for applications. This article demonstrates how to connect to a CData Connect Cloud data source from within Mendix.

CData Connect Cloud provides a pure cloud-to-cloud interface for Asana, allowing you to import data from live Asana data in Mendix — without replicating the data to a natively supported database. As you build web and mobile applications from within Mendix, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc.) directly to Asana, leveraging server-side processing to return the requested Asana data quickly.

Configure Asana Connectivity for Mendix

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

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

    You can optionally set the following to refine the data returned from Asana.

    • WorkspaceId: Set this to the globally unique identifier (gid) associated with your Asana Workspace to only return projects from the specified workspace. To get your workspace id, navigate to https://app.asana.com/api/1.0/workspaces while logged into Asana. This displays a JSON object containing your workspace name and Id.
    • ProjectId: Set this to the globally unique identifier (gid) associated with your Asana Project to only return data mapped under the specified project. Project IDs can be found in the URL of your project's Overview page. This will be the numbers directly after /0/.

    Connect Using OAuth Authentication

    You must use OAuth to authenticate with Asana. OAuth requires the authenticating user to interact with Asana using the browser. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

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

Configure Asana Endpoints for Mendix

After connecting to Asana, create a workspace and virtual dataset for your desired table(s).

  1. Navigate to the Virtual Datasets page and click Add to create a new Workspace (or select an existing workspace).
  2. Click Add to add new assets to the Workspace.
  3. Select the Asana connection (e.g. Asana1) and click Next.
  4. Select the table(s) you wish to work with and click Confirm.
  5. Make note of the OData Service URL for your workspace, e.g. https://cloud.cdata.com/api/odata/{workspace_name}

With the connection and Workspace configured, you are ready to connect to Asana data from Mendix.

Build a Asana-Connected App

With the Workspace added to Connect Cloud, you can build an app in Mendix with live access to Asana data.

Downloading the OData Metadata File

When creating a connection in Mendix, the connection flow requires a Data Source Contract File. Follow these steps to download the OData metadata file for CData Connect Cloud using curl, a command line tool:

  1. Open a command-line window for your operating system. On Windows, open the start menu, type cmd, and press the Enter key to open a command prompt. On macOS and Linux, open a Terminal window.
  2. To check if curl is installed on your system, type curl -help and press the enter key. If it is not installed, install it from the curl website.
  3. Issue the following curl command, replacing USER with your CData Connect Cloud username and PAT with the PAT you generated above: curl -u USER:PAT https://cloud.cdata.com/api/odata/{workspace_name}/$metadata -o metadata.xml
  4. Locate the metadata.xml file that the curl command created and move it to an accessible location.
