Hi,

The “Not Found” error means your route /whatsapp/public_file/<id> isn’t defined or not being picked up by Odoo. Make sure you have a controller like this:

Pyhton script:

@http.route('/whatsapp/public_file/<int:file_id>', type='http', auth='public')

def whatsapp_public_file(self, file_id, **kw):

    attachment = request.env['ir.attachment'].sudo().browse(file_id)

    if not attachment.exists():

        return request.not_found()

    return request.make_response(

        attachment._file_read(attachment.store_fname),

        headers=[('Content-Type', attachment.mimetype),

                 ('Content-Disposition', 'inline; filename="%s"' % attachment.name)]

    )

After adding, restart Odoo and update your module. Hope this should fix the link issue.

Hi,

Please refer to the module:

https://apps.odoo.com/apps/modules/15.0/all_in_one_whatsapp_integration

This module helps you to send a whatsapp message to your partners that are in sale order, purchase order, invoice and bills, and deliver orders.

Hope it helps.

To send a file link via WhatsApp from Odoo, you need to use the correct URL that Odoo uses to serve attachments.

You can directly use Odoo’s built-in route for attachments:

http://my_domain.com/web/content/21809

Make sure the attachment with ID 21809 actually exists in your database. You can find it in the `ir.attachment` model.

Also, ensure that the attachment is not restricted (check if it's public or associated with a record that the user has access to). If needed, set public=True or share it with proper access rights.
