Obtain information from a Brazilian Product Tax Invoice (Gemini)

When to use

Use this action when you want to:

• Automatically extract data from Brazilian Notas Fiscais attached to records
• Reduce manual data entry when processing invoices at scale
• Feed invoice data (such as values, items, or dates) into fields for further automation or reporting

How to configure

Step 1

Create a new automation. (This page covers only the action. For instructions on how to access automations and create a new automation, see the Automations page.)

Step 2

Select the action: In the action search bar, type Product Tax Gemini and select Obtain information from a Brazilian Product Tax Invoice.

Step 3

Connect your Google account: This action requires a Google Gemini connection. Click Log in with Google and authorize access. This only needs to be done once per workspace.

Step 4 (optional)

Choose tab: Select the table that contains the records you want to update with the extracted data.

Step 5

ID of your record: Set the ID of the record you want to update. This is typically a dynamic value mapped from the trigger.

Step 6 (optional)

Choose the field where the answer will be saved: Select the field where Gemini's extracted output will be written.

Step 7

Image: Enter the content of the image or file field that contains the invoice. If the field holds multiple files, the first file will always be used.

Step 8

Save the automation and set it to active.

Keep in Mind

• You also can use the Attachment Vision (OCR) feature, instead of this automation
• This action only processes the first file in a file field — additional attachments in the same field are ignored.
• The action does not validate whether the uploaded file is actually a valid Brazilian Nota Fiscal. If the image is unreadable or the wrong document type, the output may be empty or incorrect.
• It does not extract data into multiple fields at once — you need one action per piece of information you want to save.
• The Google Gemini connection is required. The action will not run without an active connection.
• This action does not send or submit the invoice anywhere — it only reads and extracts data within Jestor.
• File fields with no attachment will cause the action to return no output, without throwing an error.

FAQ

1 — Does this action work with PDF invoices or only images?

It works with both images and file fields. If the field is a file field, the first file in the field will be used, regardless of format. However, results may vary depending on file quality and readability.

2 — What happens if the invoice image is blurry or low quality?

Gemini may return incomplete or incorrect data. There is no built-in quality check — the action will still run and save whatever it interprets.

3 — Do I need a paid Google account to use this action?

The action uses Google Gemini via a standard Google login. Depending on usage volume, Google's own limits may apply. Jestor does not control Gemini's quota or billing.
