So the sales pitch was "seamless integration." Let's see what that actually meant for us.
We used their API to pull usage logs, then had to write a custom parser because the JSON schema changed without notice (classic). Feeding that into our billing system required more glue code than promised. The "closed-loop" part? That was on us to build. Support's solution was to point to the docs we'd already used.
Ended up replacing their streaming endpoint with a self-hosted log aggregator. More control, fewer surprise schema breaks. The real gem here was realizing their "platform" is just an API with marketing gloss. —aB

That point about the JSON schema changing without notice hits close to home. We're in the middle of evaluating a vendor who promises "stable, versioned APIs" for this exact kind of integration.
How do you even factor that risk into an RFP? Do you put a clause in about schema change notifications, or is the only real mitigation to plan for your own parser maintenance from the start? Your move to a self-hosted aggregator suggests the latter. It feels like the promised TCO never includes the engineering hours for these surprise breaks.
Yeah, the RFP question is tough. Even with a "stable, versioned APIs" promise, you need to see what "versioned" means to them. Does it mean a genuine deprecation schedule with sunset dates, or just a different number in the URL while the main branch gets breaking changes?
We started asking for their actual changelog history for the last year. If they can't show one, or it's full of "minor bug fixes" with no detail, that's a red flag. A clause about notification is good, but enforcing it is another story. The real cost is in the unplanned fire drill when a field your billing logic depends on vanishes on a Tuesday morning.
Planning for parser maintenance from the start is the only safe bet. It shifts the calculation from "if" to "when."
Spreadsheets > marketing slides.
Asking for the actual changelog history is such a smart move. We did that once and got back a three-line PDF that just said "performance improvements" for every month. That told us everything we needed to know.
Your point about enforcement is key. A notification clause is good on paper, but if they email you the change as it's deploying, you're still in that fire drill. It makes "planning for parser maintenance" less of a technical strategy and more of a business continuity one.
Keep it constructive.
Ugh, that "point to the docs" support response is the worst. Been there! The moment you realize you're on your own.

That's the perfect way to put it. It makes me wonder if the real value in these "seamless" tools is just being a well-documented, stable API. Everything else they promise ends up being a DIY project.
Your move to the self-hosted aggregator is smart. The initial setup is heavier, but you trade vendor-side chaos for your own, predictable maintenance. We did something similar after a schema break nuked a week's worth of invoicing data. Never again
Always testing.
Exactly. The "well-documented, stable API" is the product. Everything else is a feature list.
> you trade vendor-side chaos for your own, predictable maintenance.
That's the key trade-off we made too. It feels heavier upfront, but the cost becomes a known, scheduled line item instead of an emergency engineering sprint. For us, the trigger was a contract renewal where they tried to hike prices 30%. Having our own aggregator in place made walking away a two-week migration, not a quarter-long project.
It turns the vendor from a platform into a commodity supplier, which is a much healthier relationship.
