How to create an RPA flow for Postmark Data in UiPath Studio

UiPath is a Robotic Process Automation (RPA) platform with rich features and an easy-to-use UI that enables non-developers to create process automation. By using UiPath Studio, you can build an RPA program just like drawing a diagram. With the CData API Driver for ODBC, users can embed Postmark data in the workflow.

This article explains how to use the Postmark ODBC Driver in UiPath Studio to create an RPA program that accesses Postmark data.

👁 Using the CData ODBC Data Sources in UiPath

Configure the Connection to Postmark

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Using API Key Authentication

Postmark uses server API tokens to authenticate requests. Each Postmark server has its own API token, which controls access to messages, bounces, templates, and statistics associated with that server.

To obtain your Server API Token, log in to your Postmark account and navigate to the server you want to connect to. Go to API Tokens under the server settings and copy the token labeled Server API token.

After setting the following connection properties, you are ready to connect:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your Postmark Server API Token. This value is sent as the X-Postmark-Server-Token header on every request.

Example connection string:

Profile=C:\profiles\Postmark.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your-server-api-token"

Connecting to Postmark

Once the authentication is configured, you can connect to Postmark and query data from any of the available tables such as OutboundMessages, Bounces, and Templates.

Connect UiPath Studio to Postmark Data

Now you are ready to use Postmark data ODBC DSN in UiPath Studio with the following steps.

1. From the Start page, click Blank to create a New Project.
2. Click Manage Packages then search for and install UiPath.Database.Activities.
3. Navigate to the Activities and drop a Flowchart (Workflow -> Flowchart -> Flowchart) onto the process.
4. Drop a database Connect activity (App Integration -> Datbase -> Connect) after the Start activity.
5. Double-click the Connect activity and configure the Connection. 👁 Configure the Connect Activity
   
   1. Click the Connection Wizard
   2. Select "Microsoft ODBC Data Source"
   3. In Connection Properties, select your DSN (CData API Source) and click OK
6. To store Connection info, create a variable and bind to Output in the Properties section. Choose DatabaseConnection in Output.
   👁 Bind the Connection to the Output property.
   

Create an Execute Query Activity

With the connection configured, we are ready to query Postmark data in our RPA.

1. From the Activities navigation, select Execute Query and drop it on the Flowchart.
2. Double-click the Execute Query activity and set the properties as follows:
   • ExistingDbConnection: Your Connection variable
   • Sql: SELECT statement like SELECT , FROM Bounces WHERE = ''
   • DataTable: Create and use a variable with the Type System.Data.DataTable
   👁 Set the Query for the ODBC Driver.
   

Create Write CSV Activity

With the Connection and Execute Query activities configured, we are ready to add a Write CSV activity to the Flowchart to replicate the Postmark data.

1. From the Activities navigation, select Write CSV and drop it after the Execute Query activity.
2. Double-click the Write CSV activity and set the properties as follows:
   • FilePath: Set to a file (new or existing) on disk (i.e.: C:\UiPath[id]-data.csv
   • DataTable: Set to the DataTable variable you created earlier

Connect the Activities and Run the Flowchart

If they are not already connected, connect each Activity that you created to complete the RPA project for extracting Postmark data and exporting it to CSV.

👁 Connect each Activity in the Flowchart

Click Run to extract Postmark data and create a CSV file.
