Rescued Pets Need Creative Data Transfer Solution

Those who have seen my other posts (thanks for the help, again) know that I have been working on an adoptable pet application for Wix sites. I am doing the prototype for one small rescue in Kentucky and their pet system will go live this week.

The public-facing portion of the system is pretty much done and the back-office “shelter management” portions are working nicely, too. I have one critical component that has me 100% stumped. I need to transfer their available pet data to a 3rd party technology organization, which then distributes the adoptable animals to many dozens of other pet search websites, like Petfinder, etc.

I am building the Wix system based on an existing software product I wrote years ago that has a desktop component and which uses ftp to transfer the data in a .csv file. The long-term solution is for the 3rd party to open up an API to their back end so I can use http to send the data. Until that happens (which, given they are an all volunteer or that has some communication challenges, may be a while) I need to somehow get regularly, scheduled csv files onto my computer of the available animals in the system. And, naturally, I would prefer not having to log in manually to get them. An automated ftp download or some other similar solution would be best for the short term. But, I am kind of stumped.

Do I need to run some sort of web server on my computer so I can write a file to it from Wix? If so, is there a straight-forward way to write or send a csv file from wix?

Thanks in advance!
