Hello Bryan, thanks for the great article!

I would like to ask you 2 questions about the way your integration with other services.

Since you have integration with hundreds of services, I guess not all of them push an event to you when something happens. So, what do you do? Do you periodically check the change of the data you are interested in? If that's the case, how do you deal with the stuff like api rate-limiting?

Second, how do you keep track of API changes happening in the services you are integrated with? Do you have some sort of automated tests which checks if the end-points you are using are still working in a way you expect?

Cheers!
