What should every business know before starting an API integration?

[garycoyne]

Our company is planning an API integration because our existing software doesn't share data properly, and it's creating extra work for everyone. I've been reading different articles and came across Inovio Soft during my research, but I want to hear honest experiences from people who have actually gone through this process. Was the project more difficult than you expected? What problems did you face, how did you solve them, and what advice would you give to someone planning their first API integration project?
