## Example workflow: Gmail invoice → ADP → Google Drive

<Steps>
  <Step title="Authorize Gmail">
    Authorize the Gmail account and set email filters, such as invoice in subject, specific supplier, or specific label.
  </Step>

  <Step title="Filter documents automatically">
    Built-in filters exclude files that do not match the conditions. Default rules:

    * Attachment title contains `invoice`, `receipt`, `expenses`, or `fee`.
    * File size is less than 50 MB.
    * Format is `.jpeg/.jpg/.png/.bmp/.tiff/.pdf/.doc/.docx/.xls/.xlsx`.
  </Step>

  <Step title="Call the Laiye ADP node">
    Enter API Key, App Secret, and Access Key. ADP returns structured JSON with 10+ text fields, such as Invoice Name, Invoice Number, and Date, plus full line items such as Item Name, Quantity, and Unit Price.
  </Step>

  <Step title="Store files in Google Drive">
    * Processed files are converted to binary and imported into Google Drive Sheets.
    * Unprocessed files are stored in the **Untreated Document** folder.
    * You can change Parent Folder to customize the path.
  </Step>
</Steps>

## Use cases

* **Multi-supplier integration**: Process invoices from many suppliers and archive them automatically.
* **Accounting firm batch processing**: Handle more client invoices without increasing headcount.
* **Cross-border trade**: Process multilingual and complex Global Invoices without manual setup.
* **Small and midsize technology companies**: Extract reimbursement amount, date, and invoice number without manual entry.
