6. Map Amount to {{$node["Receipt Detail Extraction"].json["predictions"][0]["total"]["amount"]}} and Currency to {{$node["Receipt Detail Extraction"].json["predictions"][0]["locale"]["currency"]}}.
7. Map Added by to {{$node["Telegram Receipt Intake"].json["message"]["chat"]["first_name"]}} {{$node["Telegram Receipt Intake"].json["message"]["chat"]["last_name"]}}.

Step 4: Configure Output and Notifications

Step 5: Test and Activate Your Workflow

Run a controlled test to confirm each node processes a receipt correctly, then turn on the workflow.

1. Click Test workflow and send a receipt image to your Telegram bot chat.
2. Confirm Receipt Detail Extraction returns receipt fields and Assign Expense Fields outputs the mapped data.
3. Verify a new row is appended in Google Sheets by Append Expense Spreadsheet.
4. Check that Telegram Confirmation Notice returns a confirmation message and Text Alert Dispatch sends the SMS.
5. When successful, switch the workflow to Active for production use.
