API monitoring correct and fast, 24x7
Downtime caused by API performance has serious business impact. Use Checkly's deep but easy to use API monitoring solution to check your mobile, webapp or IOT API for performance, uptime and correctness.
Monitor for performance
Checkly records the response time for each request, down to TCP, DNS and first byte times. Add assertions for maximum response time.
Monitor for correctness
Check payloads, return codes, headers, and authentication. Dive inside JSON payloads and validate specific items.
Checkly can monitor your APIs from 16 global data center locations.
Setup & Teardown scripts
Import from tools you know
Checkly's cUrl and Swagger API importers create fully fledged API checks with just a couple of clicks.
Integrate your API monitoring into your QA or continuous delivery process by triggering adhoc runs from Github or the command line.
How it works
Create an HTTP request
Import your HTTP requests or assemble one by hand. Checkly gives you full control over all HTTP request options: HTTP method, URL, query parameters, headers, and body. Add credentials or a Bearer token for authentication.
Add API check assertions
Checkly's assertion matrix helps you create as many assertions per check as you want. Monitor your API for correct response times, HTTP status code, plain text or JSON bodies and headers. Drill into JSON payloads with JSON path or user regular expression.
Customize setup & teardown
If needed, you can take full control of how your request executes. Use setup scripts to cryptographically sign requests, fetch OAuth tokens and update request attributes before any request is done. Use teardown scripts to clean up test data or scrub sensitive data from the response.
Monitor your API every minute
We monitor your API as often as once per minute. This gives you a consistent and accurate view of your API performance. Next to aggregating metrics, we give you access to each result from each of the configured data centers.
Alerting for any situation
When a check fails, you and your team need timely and actionable insights to address any down time. Add Slack, SMS, email or Pagerduty: Checkly's alerts give you the right information whatever alerting medium you choose. Need more control? Webhooks give you full access to the JSON data we use ourselves for alerting. Learn more
