Finally Trust and Understand your APIs

Innovating is hard! Super hard! Everyday brings a new curveball. How do you secure what you can't see? How do you fix a problem you can't find? The list of problems modern backend systems have to deal with are endless. And that's why we're here;

All the tools you need to understand what's going on in your APIs, Investigate incidents and generate insights. With daily & weekly reports on everything going on in your services.
Anomalies and Data validation


Apitoolkit will verify that your payloads are returning the correct data and would notify you if we notice changes.

Founders Note

Or Why we are solving API observability

A few years ago, I was a new hire at a food delivery company, migrating a legacy service from PHP to Golang. We implemented the fields listed in the swagger docs, and compared the responses from the legacy service to the responses of the new service, fixing differences until everything matched.

After weeks of implementation and testing, we rolled out the new service after running tests to make sure everything worked as expected. But immediately we looked at our order monitoring charts, we knew we had messed up. Within 10mins, 20k orders lost. I was terrified. What happened?

Apparently in a couple countries we ran in, a particular field which was expected by the apps was no longer being sent, prevent placing of orders. We had no idea since this field was not in the inherited documentation, and was only applicable in a couple countries which were not part of the samples we manually tested.

We rolled back and fixed the issue, but I was sad that there was no tool which could have detected this issue faster.

Years later, this is that tool, and we would love to listen to similar stories you’ve experienced, and help make such stories a thing of the past.
