Bot Creation

In Automation Anywhere cloud Control Room, make a new boat for merging PDF files. We’ll be using the “REST Web Service: Post Method” action to consume “/pdf/merge” API endpoint. We’ll also get the “Message Box” action attached to the API call output. The final bot structure will look like this.


URI Configuration

Configure URI to “” in “Rest Web Service: Post Method” action.


Headers Configuration

Prepare the Header key with the name “x-api-key” with the API key. This API key is necessary for consuming APIs. API keys can be found at


Request Input Configuration

Configure input data to the REST web API call. Here, we’ve created very basic service request data in JSON format that looks like this. Here, we have multiple PDF URLs to be merged in a comma-separated format.

{"url": ",", "name": "name"}


Configure Rest API Output

Generate an output variable of type dictionary which will hold the API call response.


Configure Message Box

Drag and Drop the “Message box” action and attach it after the “REST Web Service: Post Method” action. Here, we’ll configure “message to display” with the “Body” property of the output variable.


Execute Bot and Review Output

With these configurations completed, we’re now ready to execute the bot and get the output message box below.

If we open the resulting URL, we’ll see it’s containing a PDF with two pages.
