Automated png export to a server/database

Hello!

I was wondering whether it’s possible to automate exporting frames in a png format to our company’s server/database via any API/plugin. 

We want to include the images in our online documentation. To prevent time consuming manual reuploads in the future if mockups change, we want to automate the proccess and redownload images in a recurring manner or push changes when needed.

Do you have any solutions or suggestions on what could we look into?
