• Refer to PDF4me API documentation for specific endpoint responses
• Use dynamic content parsing in subsequent actions

Common Patterns

Common Response Patterns

Typical response structures:

{
  "File Content": "[Binary Content]",
  "Status": "Success",
  "Message": "Operation completed"
}

Or

{
  "Data": {...},
  "JobId": "job_123"
}
