Dropbox Download File Application Steps
1. Defining the Action in UI Design
Open your Kuika project.
In the UI Design module, select the screen where the file will be downloaded.
Add a Button element (e.g., “Download File”).
Click on the button and select the + ADD ACTION → Dropbox → Dropbox Download File action.
2. Configuring Parameters
settings: Select the Dropbox API settings you created in Configuration Manager.
path: Specify the path of the file to be downloaded (e.g., /Reports/2025/Annual.pdf).
Use Case: Downloading Reports
In a reporting application, when the user clicks the “Download Latest Report” button, the relevant PDF file in Dropbox is downloaded to the application.
Steps:
Add a “Download Report” button.
Define the OnClick → Dropbox Download File action.
Link the full path of the file to the path parameter as fixed or dynamic (from Form Input).
When the user clicks the button, the file is downloaded and becomes available within the application.
Dropbox Download File Advanced Customizations
Dynamic File Selection: The file selected by the user from the list can be downloaded dynamically.
Conditional Download: If the file does not exist, a warning can be displayed to the user.
Using the Result: The downloaded file can be transferred to another action (e.g., adding it to an email attachment).
Format Control: Only files with specific extensions can be downloaded (e.g., .pdf, .xlsx).
Technical Risks and Controls
The path must not be empty. Since it is a required parameter, leaving it blank will cause the operation to fail.
Invalid path: If the file path is entered incorrectly, the action will return an error.
Settings must be configured correctly. If the Dropbox API setting is not configured in Configuration Manager, the action will not work.
File size: Download time may be extended or a timeout may occur for very large files.
