Automate Tasks in Power Automate Using the CData API Server

Power Automate (Microsoft Flow) makes it easy to automate tasks that involve data from multiple systems, on premises or in the cloud. With the CData API Server, line-of-business users have a native way to create actions based on QuickBooks Online triggers in Power Automate; the API Server makes it possible for SaaS applications like Power Automate to integrate seamlessly with QuickBooks Online data through data access standards like Swagger and OData. This article shows how to use wizards in Power Automate and the API Server for QuickBooks Online to create a trigger -- entities that match search criteria -- and send an email based on the results.

Getting Started

---

Set Up the API Server

Follow the steps below to begin producing secure and Swagger-enabled QuickBooks Online APIs:

Deploy

The API Server runs on your own server. On Windows, you can deploy using the stand-alone server or IIS. On a Java servlet container, drop in the API Server WAR file. See the help documentation for more information and how-tos.

The API Server is also easy to deploy on Microsoft Azure, Amazon EC2, and Heroku.

Connect to QuickBooks Online

After you deploy, provide authentication values and other connection properties by clicking Settings -> Connections in the API Server administration console. You can then choose the entities you want to allow the API Server access to by clicking Settings -> Resources.

QuickBooks Online uses the OAuth authentication standard. OAuth requires the authenticating user to log in through the browser. To authenticate using OAuth, you can use the embedded OAuthClientId, OAuthClientSecret, and CallbackURL or you can obtain your own by registering an app with Intuit. Additionally, if you want to connect to sandbox data, set UseSandbox to true.

See the Getting Started chapter of the help documentation for a guide to using OAuth.

You will also need to enable CORS and define the following sections on the Settings -> Server page. As an alternative, you can select the option to allow all domains without '*'.

1. Access-Control-Allow-Origin: Set this to a value of '*' or specify the domains that are allowed to connect.
2. Access-Control-Allow-Methods: Set this to a value of "GET,PUT,POST,OPTIONS".
3. Access-Control-Allow-Headers: Set this to "x-ms-client-request-id, authorization, content-type".

Authorize API Server Users

After determining the OData services you want to produce, authorize users by clicking Settings -> Users. The API Server uses authtoken-based authentication and supports the major authentication schemes. You can authenticate as well as encrypt connections with SSL. Access can also be restricted by IP address; access is restricted to only the local machine by default.

For simplicity, we will allow the authtoken for API users to be passed in the URL. You will need to add a setting in the Application section of the settings.cfg file, located in the data directory. On Windows, this is the app_data subfolder in the application root. In the Java edition, the location of the data directory depends on your operation system:

1. Windows: C:\ProgramData\CData
2. Unix or Mac OS X: ~/cdata

[Application]
AllowAuthtokenInURL = true

Add QuickBooks Online Data to a Flow

You can use the built-in HTTP + Swagger connector to use a wizard to design a QuickBooks Online process flow:

1. In Power Automate, click My Flows -> Create from Blank.
2. Select the Recurrence action and select a time interval for sending emails. This article uses 1 day.
3. Add an HTTP + Swagger action by searching for Swagger.
4. Enter the URL to the Swagger metadata document:

   https://MySite:MyPort/api.rsc/@MyAuthtoken/$oas

5. Select the "Return Customers" operation.

6. Build the OData query to retrieve QuickBooks Online data. This article defines the following OData filter expression in the $filter box:

   FullyQualifiedName eq 'Cook, Brian'

   See the API Server help documentation for more on filtering and examples of the supported OData.

Trigger an Action

You can now work with Customers entities in your process flow. Follow the steps to send an automated email:

1. Add an SMTP - Send Email action.
2. Enter the address and credentials for the SMTP server and name the connection. Be sure to enable encryption if supported by your server.
3. Enter the message headers and body. You can add QuickBooks Online columns in these boxes. 👁 An email to be populated with results from an OData query. (Salesforce is shown.)
