Example 1: Send QR and Barcode images as email attachments
In the following example, Barcode images are sent as email attachments using the sendmail task.
Event organizers email barcoded tickets to attendees, allowing quick and seamless check-in by scanning the barcode at the entrance.
// Retrieve the QR code image from input qr_code_image = input.QR_Code.file; // Define email details email_subject = "Ticket for Night Concert"; email_message = "Hi Amy, your ticket to the most spectacular concert of the year is confirmed!\n" + "Please scan the attached QR code at the entry and carry a valid ID for verification.\n" + "Thank you for joining us—we can’t wait to see you there for an unforgettable experience!"; // Send the email with the QR code attachment sendmail [ from : zoho.adminuserid to : zoho.adminuserid subject : email_subject message : email_message attachments : file : qr_code_image ];
Example 2: Send barcode images to other services using invoke URL
The following example pushes the QR or Barcode images to the services you're trying to integrate with using invokeURL() task.
Automatically push patient test reports with barcode identifiers to diagnostic systems, enabling seamless retrieval, tracking, and processing of medical records.
// Step 1: Prepare patient report metadata test_report = Map(); test_report.put("patient_name", "John Doe"); test_report.put("report_id", "TR-12345"); test_report.put("barcode_image_url", "https://example.com/barcode/TR-12345.png"); // Step 2: Format the request with essential report metadata request_payload = Map(); request_payload.put("patient_name", test_report.get("patient_name")); request_payload.put("report_id", test_report.get("report_id")); request_payload.put("barcode_file",input.barcode.file); // Step 3: Push the report to the diagnostic system along with the barcode identifier response = invokeUrl [ url: "https://api.diagnosticservice.com/v1/reports" type: POST body: request_payload connection: "diagnostic_api_connection" ]; // Step 4: Log the response for audit and debugging info response;
