Odoo OCR Integration — Auto-Fill Purchase Invoices

Overview

Odoo's accounting module can be extended with Cargoffer OCR. A custom module sends PDF invoices to the OCR API and fills the vendor bill form automatically.

Odoo Python Code

python

import requests
from odoo import models, api

class AccountMove(models.Model):
    _inherit = 'account.move'

    def action_ocr_extract(self):
        self.ensure_one()
        api_key = self.env['ir.config_parameter'].sudo().get_param('ocr.api_key')
        
        # Upload PDF
        with open(self.invoice_pdf_path, 'rb') as f:
            r = requests.post(
                'https://ocr.cargoffer.com/api/upload',
                headers={'Authorization': f'Bearer {api_key}'},
                files={'file': f})
            job = r.json()['job']
        
        # Analyze
        r = requests.post(
            f'https://ocr.cargoffer.com/api/analyze/{job}',
            headers={'Authorization': f'Bearer {api_key}'})
        data = r.json()
        
        # Fill invoice
        inv = data['results'][list(data['results'].keys())[0]]
        self.invoice_date = inv.get('issue_date')
        self.amount_total = inv.get('totals', {}).get('total')
        return True
