Every guide says "just set up the webhook and you're done." But what happens when the vendor changes their payload format? Or silently deprecates an API version you're stitching together?
I write tests for every integration point. Not just "does it run," but:
* Does it fail gracefully when the third-party service is down?
* Does it handle the unexpected 429 rate limit response?
* Does the data transformation logic break on a null field?
* What's the cost of a retry loop on a usage-billed API?
Otherwise, you're just building a liability. The TCO isn't the SaaS subscription—it's the 2 AM page when your "glue" melts.
