Connecting a legacy JSON Feed

​

Steps to Add or Modify a JSON Feed Connection

​

1. Start the Data Provider Wizard

• Open the Data Provider Wizard by following the instructions in Adding a Data Provider or Editing a Data Provider.
• Select JSON Feed as the provider type.

​

2. Specify the JSON Feed URL

• Enter the JSON Feed URI (URL) pointing to the data source.
• Click Preview to view a sample of the retrieved data.

​

3. Choose the Request Method

• GET (default) → Retrieves data without modifying it.
• POST → Used for sending additional parameters.
  • If POST is selected, enter the request body with required parameters.

​

4. Configure Data Formatting

• Flatten Hierarchical Data → Converts nested JSON structures into a flat table format.
• Include Parent Levels Column Names → Adds parent-level identifiers for hierarchical relationships.
• Create Additional Columns Without HTML Tags → Removes HTML formatting and extracts plain text.

​

5. Configure Security and Authentication

• Authorization (if required)
  • Enable Authorization Required.
  • Enter UserID, Password, and Domain.
• Proxy Server (if applicable)
  • Configure proxy settings if your network requires authentication.
• User-Agent Identification
  • If required, specify a custom User-Agent string (useful for API access restrictions).

​

6. Finalizing the JSON Feed Setup

• Click Finish to complete the configuration.

Important Considerations

• PADS4 Data Server
  • If using a PADS4 Data Server, ensure the JSON feed is accessible from the server.
  • If not using a Data Server, ensure that both PADS4 Designer (for previewing) and Viewers can access the JSON feed.
• Hierarchical JSON Data Handling
  • If your JSON structure has multiple levels, ensure that Flatten Hierarchical Data is enabled for a structured output.
