# Import invoice as image
## Context:
Let's take the same concrete example as before, but this time, instead of a PDF invoice, we will have an invoice in image format.
## Implementation in SIMAX
To import an invoice image, your OpenAI API Key must be configured in **Settings > Plug-ins and option selection and \[Installation].**
Next, go to **Purchase > Supplier Invoice > Import a Purchase Invoice.**

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://doc.simax.fr/documentation-simax-anglais/functional/purchase/import-invoice-as-image.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
