How one get a PDF invoice into odoo

i am looking at this and i dont get any example about how to get a PDF invoice imported into odoo

anyone got any hints?

It doesn’t appear that the default node has functionality to do that, see if you can find a REST API call to upload a file in their developer’s documentation and if there is one, you can use HTTP Request node to send such request.

uploading the pdf does nothing because the PDF values are not inserted like expenses

If you don’t need to upload the pdf itself (which I assumed from your original message), you need to extract data from the pdf first and only then call odoo. Is this what you are looking for? Do you have an example PDF that you are working with? PDFs can be text of images and depending on that extracting information from them can be easy or a bit trickier.

this what odoo generates and can be used like a demo for what you need to insert

This is a great example, but it doesn’t address the question from my post - is it a text pdf or an image pdf? What is the immediate issue you are trying to solve - extracting information from PDF or uploading information to odoo? If it is extracting information - which information do you need to extract? Do you have a pdf version of the above image?

that is not the problem an mistral-ai makes the OCR if needed, the problem is getting the lines, product description, quantities, prices, taxes, invoice number, client details, in odo
