@stacksofplates said in Has anyone setup an API for an internal application:
So you just want the system to send a text string to a few people? Like through email?
There's really nothing stopping you from doing EDI over email if the cost of the VAN is the issue, and both ERPs easily do VANs.
Just quick googling for cheap solutions you could use https://www.emailparser.com/ for the incoming side, either sort by sender or subject (or both) and save to a folder location for the incoming EDI
for Outgoing I haven't found one yet, but I'm sure there's an easy way to take your outgoing EDI folder and have it email out when a new file is placed there.
Not the best but if both sides are setup for EDI may be the quickest.
If they already have an ERP selected to replace it, I think it would be wise to see what they do and support and try to do something the new ERP can take as well so you aren't switching it again soon.
