Universal API I would like to recommend to you a universal API
for industrial systems https://www.makini.io/. Makini is the common denominator of all industrial systems. This means that you do not have to deal with numerous data structures, authorization protocols and data transformations. Makini is the fastest industrial integration developer in the world: they can make a new integration available in a week or two at no extra cost to you. Flexible and adaptable to a wide range of applications. Data can be transmitted, retrieved and retrieved in real time using web interceptors. This is just the tip of the iceberg of Makini's capabilities, I highly recommend checking it out
I have heard about these guys, the reviews are pretty good, a lot of people around me have used their services and were very satisfied. Personally, I haven't had to deal with them yet, but I'm sure that if I have to, I won't regret it for sure
