Develop Ipad-App to Scan Datamatrix and post JSON

We are producing leaflets for the pharma industry. Therefore we have to ensure that we pack correctly and without mixups. We need an Ipad-App, which matches the QR-code of box against the Datamatrix of a bunch of leaflets. The matching is actually done in our system, you just have to send the data via to our RestfulAPI. Pls find below Workflow Additional information Scribble of User Interface Scan QR Code of box Status: “Pls scan new box.” Send JSON via RestAPI { "boxID": "value of QR-code", "cartonID": “value of Datamatrix” >>> “” empty as you have not scanned it } Retrieve 200Response { "bunches_in_box": 15, "bunches_to_scan": 15, “new_box”: true, “status”: “OK, Pls scan 15 batches for BoxID. 1234” } Change status in Display Scan Datamatrix of Bunch Send JSON via RestAPI { "boxID": "value of QR-code", "cartonID": “value of Datamatrix” } Retrieve 200Response { "bunches_in_box": 15, "bunches_to_scan": 15, “new_box”: true, “status”: “OK, Pls scan 15 batches for BoxID. 1234” } IF NEW box== true Display Status Go to 1. ELSE Display Status Go to 5. Error Handling On error you will recieve 400-Response: { “status”: “Error.
