How to download listings in MarketPlace at Designer?

All the scripts and solutions added in the Marketplace will be available in the Designer, empowering users with a rich library of pre-built components. This library includes integrations that facilitate seamless connections to external services, as well as custom activities, allowing users to incorporate specialized functionalities into their automation workflows.

Follow the below steps to download and integrate the scripts:

1. Launch the designer.
2. Navigate to the “MarketPlace”.
3. Here chooses the specified template that is suitable for your solutions.
4. Click on it and a pop-up window will appear on the screen. Here I am choosing the “PDF” specified as “Reusable component”.
5. It displays the description of the chosen listing along with the versions available, listing type, created by, license file and URL.
6. Review the “Terms & Conditions” and then proceed to check the box.
7. Select the “Download” option to download it in your local system.
8. Now, easily integrate the script in your automations.

You can view the downloaded MarketPlace file in the following path “C:\Users\Username\Documents\Robility\Marketplace”.

Steps to integrate the listing in the solutions/templates:

Example

In the following example, I have downloaded the “PDF” listed as “Reusable component” to integrate into the solutions.

1. Open an existing template or create a new template.
2. Navigate to the toolbox section and scroll to the end of the features.
3. Here, you will find the scripts downloaded under the feature as “Reusable Component”.
4. Now, I have dragged and dropped the “PDF” which acts as the “Load Environment” activity. It also acts as scope for the list of scripts available in it.
5. Now, navigating to the “PythonPath” in the properties to provide the path of the “Python” application. Here I am providing the value in the variable as “Path”.
a. There are two steps to provide the variable in the property.
b. Step 1: Click on the variable pane, enter your preferred name (here, I’m using “Path”), and choose the data type as “String” since the output value accepts the string data type. And provide the path of the python application as default value.
c. Step 2: Double-click on the variable parameter in the “PythonPath” section and enter a name as “Path”.
6. Now, I am adding the “Image conversion” script into “LoadEnvironment – PDF” activity to automate in the solutions.
7. Here I am choosing the file name from the drop-down as “Image_Conversion.py”.
8. Now, the “MethodName” option will be available and here I am choosing the method from the drop-down as “convert_pdf_to_images”.
9. Navigating to the “Parameters” in the properties section to provide the required inputs for the script.
a. Click on the Three dots and the “Parameters” dialog box will appear on the screen with the required inputs.
b. Here are two inputs required to automate the script. You can either enter the input values here in the specified datatype in the “Value” field or can hardcode the values in the specified datatype.
c. I have directly provided the values in the “Values” field for both the inputs, now click on “OK” button.
10. The parameter which indicates “OUT” as direction is indicated as the output of the activity. Here the “result” is indicated as “OUT”, so declaring a variable there to view the output.
a. Now, I am declaring a variable in the “Variables” section with the similar name “result” along with the specified datatype as “Jobject”.
11. Now, to view the output, add the “Writelog” activity and pass the required inputs.
12. Save and execute the bot.

Now, the script will be loaded and starts to create a virtual environment, which might get delayed on the first execution. Then the bot proceeds to execute the script.

The bot will write the output in the “Output” section using the “writelog” activity.
