Put plainly, this is a platform that allows you to connect web services. So yes, it is a linking tool for third party APIs. But there's a lot more than that here. The differentiator is in how that manifests itself. So with something like IFTTT, you're given the option to connect X to Y, with finite versions of X and Y to connect. So while it fits a number of use cases, there's a lot that's left to be desired. Dexter gives you the ability to connect X to Y, but since you can deploy your own code, the developer / user and the API endpoints they are using are what effectively limits the number of permutations. Additionally, you can connect far more than two endpoints, can switch based on expressions, can fetch from a data store, can wait for user input and more. Hope that helps!
I understand that I can link Google Docs to Slack.
Is it like a linking tool for third-party APIs?
