Merge PDF Files Stored in an Entity List

Note: This feature is available in DRUID 5.25 and higher.

If you store PDF files in an entity list of files and you want to merge them, you can use the Document Builder.

On the desired flow step, in the PostAction section, add a connection action and provide the following details:

Parameter	Description
Name	The name of the action. The field is mandatory.
Description	A brief description of the action that might be useful for other tenant admins. The field is mandatory.
Category	Define on the spot when creating the action. Useful to easily find the actions in the Integrations list. The field is mandatory.
Icon	Select the icon that best describes the integration. It helps you easily identify the integration action in the list of integrations. If no icon is selected, DRUID will show default icon.
Request Entity Name	The entity used by the chatbot to send data to the external app via the current action.
Response Entity Name	The entity used by the chatbot to receive data from the external app via the current action.
Is Active	Tick to activate the connector action.

Click Save.

Add a Document Generator task (Word or Excel).

Click on the integration task and in the right-side editor provide the details described in the table below.

Field	Description
Description	Enter a brief description for the task. E.g., Invoice Generation.
Generated Extension	Select PDF.
Password Protected	Tick on PasswordProtected to password protect a pdf output document. On the flow that generates the PDF document, before calling the DocumentGenerator connector, make sure to set the password value in field [[ChatUser]].PasswordForProtectedFiles in the Set Variables section. Important! If you're using [[ChatUser]] as request and response entity on the connector, the password will be saved in clear in the conversation history.
Merge PDF templates	Tap on Merge PDF templates.
PDFs to be merged	Note: This field is available only if you tap on Merge PDF templates. Enter the name of the entity field (of type entity list of files) that stores the PDFs you want to merge (e.g., [[Account]].Files).
Dynamic File Name	Specify the file name of the generated document either hard coded (e.g., "Invoice April") or as a value from the context: an entity field (e.g., [[Employee]].Name) or a local variable. If the field is empty, DRUID will use the template file name as file name of the generated document.
ProjectResultToEntityPath	Select the entity field (a field of type file created on the request entity) that will store the generated document.

Click the Save icon (), then the Publish icon () at the top of the right-side editor.
