Enquiry regarding box.com authentication onto a customer's files for automation

Hi there

We have a requirement for the following:

• to connect to a customer's Box.com folder
• run recursive searches against it every 10 mins or so, looking for files with specific extensions and specific metadata
• When a match comes up, the files will be downloaded to a our local system and the metadata will be updated to reflect this.

Key question is as follows:

• Our customer has an Enterprise account, we do not.
• Should we use our own Box.com developer account to create the solution, and request access to the relevant locations from the customer when the time is right - will this work?
• Ideally we'd like to use this integration in case other customers use Box too
• Is there other information regarding this?

How would it work?

• Our customer gives access to a specific location to our development account e.g. ***email address removed for privacy*** -
• Our developer account ***email address removed for privacy*** has a developer account with an API access token 
• This token is used with a Python SDK
• We can query the same files via the SDK as we would see in the web view?

Many thanks in advance
