Check invoice arithmetic from incoming email
Ask Notis to verify the arithmetic in invoice details that are available from a new message or supplied file.
Trigger
New Gmail Message Received Trigger
Triggers when a new message is received in Gmail.
Action
Execute Code
Execute python code in a sandbox and return any result, stdout, stderr, and error. use /home/user folder to write/read files. try to not use plt.show() as the code is executed remotely. use files for image/chart output instead.
Why this helps
Manually checking invoice arithmetic in a crowded inbox makes routine review harder to keep up with.
- Calculate totals from available line items.
- Surface mismatches in the run report for human review.
- Avoid assuming an attachment is accessible when it is not.
Setup
Build it in a few focused steps.
- 1Connect Gmail and Codeinterpreter once in the Notis portal.
- 2Create an automation named for invoice total checks.
- 3Describe in one instruction which available invoice data to calculate and how to report missing information.
- 4Choose the New Gmail Message Received trigger and a report destination.
- 5Test with one real invoice email and confirm the data is available and parsed correctly.
Questions about this workflow
Will the automation approve or pay an invoice?
No. This workflow runs a calculation and reports findings for review.
What if the invoice is only in an inaccessible attachment?
The script needs the invoice data available in the sandbox. The run should report missing data rather than infer totals.

Email Sent
Triggers when a Gmail message is sent by the authenticated user. It polls the 'SENT' label and emits metadata including sender, recipients, subject, timestamp, and thread ID.
