a) Yes Reference: https://learn.microsoft.com/en-us/ai-builder/prebuilt-receipt-processing

Yes, receipt processing in AI Builder does require a photo token when using the camera control in the canvas app. Explanation: When using AI Builder's receipt processing model in a canvas app, the model processes receipts by analyzing the data from the receipt image. The camera control in the canvas app is used to capture a photo of the receipt. This photo is then passed to the receipt processing model for analysis. The photo token is the unique identifier for the photo or image captured by the camera control, and it's necessary to pass this token to the receipt processing model so that the model can process the receipt data (such as extracting the total amount, vendor name, date, and other details). So, when implementing this, you need to capture a receipt image using the camera control and then provide the corresponding photo token to the AI Builder receipt processing model for it to process the receipt data. In summary, yes, a photo token is required for receipt processing when using the camera control in a canvas app.
