Whatssaapi?
Jun 17, 2026
I’ve keep paying for SaaS tools but refusing to use them.
Here’s what I do instead.
Grab a bearer token from Chrome DevTools.
Map the endpoints with Claude/Codex.
Do exactly what I want, directly through the API.
I used to waste hours fumbling through interfaces. Now I get instant answers: it either works, or there’s no endpoint.
APIs do lot’s of things that aren’t supported by the web app.
undelete items
use exact values instead of presets (i.e. in time ranges)
better search params
When I don’t like part of the service, I replace it!
I use an AI SDR to automate outbound, which has 4 steps:
Find profiles
Enrich them (get contact info, etc)
Generate custom messages
Send messages
Everything is great except Step 3. I hate the custom messages. They’re cringey and don’t sound like me.
So I rebuilt it!
I still let the service handles steps 1 and 2 (find and enrich profiles).
Then I get the profiles through the API, and generate the custom messages using my own logic.
I upload my messages with the API and let the service takes back over for Step 4.
It’s the natural interaction pattern now that we have coding agents.
Interfaces are becoming a hindrance; they’re hard to build, tedious to maintain, and confusing to users. They expose only a small slice of the underlying business logic, and you can’t replace parts you don’t like.
Software will become APIs, not apps. Software-as-an-API. That’s what’s SaaAPI.
