API Testing

API testing that follows the whole journey, not just one endpoint

API testing often stops at single requests, while real bugs hide between calls and screens. Robonito chains REST API requests into multi-step workflows, checks every response, and joins API and UI steps in one test.

Teams that refuse to trade speed for quality ship with Robonito

01The problem

The API passed. The feature still broke.

Your services change constantly, and each one has its own tests, owners, and assumptions. The bugs that hurt live in the hand-offs.

01 / 03

Isolated endpoint checks

Each endpoint returns a success on its own, but the order flow fails when the token from login never reaches the payment call.

02 / 03

API and UI tested apart

Backend and frontend suites run separately, so nobody sees that the API saved the record while the screen still shows the old value.

03 / 03

Scripts only one person understands

API tests written in code live with one engineer, and when they're out, nobody wants to touch the suite.

02Capabilities

API testing without writing request code

Robonito handles the requests, the chaining, and the checks, so your team can focus on what the API should do.

REST API requests

Send HTTP requests to your REST endpoints and check what comes back, all from a no-code test case.

REST
HTTP requests

Chained multi-step workflows

Pass values from one response into the next request, so a test can sign in, create an order, and confirm it the way a real client would.

Chaining
Workflows

Assertions on responses

Check status codes, fields, and values at each step, so a quiet change in a response is caught before it reaches your users.

Assertions
Responses

API and UI in one journey

Create data through the API, then verify it on screen in the same test, or the other way around, so you test the feature as users experience it.

API + UI
End-to-end

Optional script injection

When a step needs custom logic, add a script. When it doesn't, stay fully no-code.

Runs in your pipeline

Trigger API suites from your CI/CD pipeline or on a schedule, with results and root causes in the same reports as your UI tests.

03How it works

How API testing works with Robonito

1
Define the requests
Add HTTP request steps for the endpoints in your flow, or describe the flow in plain language and refine what the agent drafts.
2
Chain and assert
Carry values between steps and add checks on each response. Mix in UI steps wherever the journey touches a screen.
3
Run and review
Run on demand, on a schedule, or from CI/CD. Failures come back with a step-by-step log and a root-cause note.

04Use cases

API testing scenarios from real release cycles

Order flow across services

A team chains login, cart, payment, and order-status calls into one test, so a broken token hand-off fails loudly in testing instead of quietly in production.

Seed data, then check the screen

A QA lead creates a customer record through the API and has the agent confirm it appears correctly in the web app, all in one run.

Response check after a backend refactor

After a refactor, response assertions catch that a field was renamed, one the mobile app still depends on, before the release goes out.

05Proof in every run

Clear proof for every request

When an API test fails, your team needs to know which call, which value, and why.

Step-by-step request log

Every request and check in the chain is recorded in order with its result.

Proof you get: Step-by-step run log for each API call

Root-cause notes

The agent explains where the chain broke and what it expected to see.

Proof you get: AI root-cause summary on failures

Combined reporting

API and UI results land in the same execution overview, so one report answers 'Are we ready to ship?'

Proof you get: Execution overview and PDF report

07FAQ

Frequently asked questions

What is API testing?

API testing checks that an application's APIs return the right data, status, and behavior when called. Instead of clicking through screens, tests send requests directly and verify the responses. Robonito lets you build API tests without code, chain requests into multi-step workflows, and combine them with UI steps so you test complete features, not isolated endpoints.

How do you automate REST API testing without code?

In Robonito, you add HTTP request steps to a test case, set the checks you expect on each response, and pass values from one call into the next. No request code is needed. Tests then run on demand, on a schedule, or from your CI/CD pipeline, and failures come with a step-by-step log and a root-cause note.

Can I combine API testing and UI testing in one test?

Yes, Robonito lets you mix API and UI steps in the same journey. For example, a test can create an order through the API and then confirm it on screen, or submit a form in the UI and check the API response afterward. This catches the bugs that live between your backend and your frontend.

What are chained API tests?

Chained API tests are multi-step tests where values from one response feed the next request, such as using a login token to call a protected endpoint. They mirror how real clients use your API. Robonito supports chained workflows with assertions at each step, so you can see exactly where a multi-call flow breaks.

Which Robonito plan includes API testing?

API testing is included on the Pro and Custom plans. Pro is $199 a month and adds mobile, desktop, and API testing, with 1,000 test cases, 30 hours of execution, five parallel runs, and 24-hour support. Custom adds unlimited test cases, custom parallel runs, and every platform, with a custom SLA and dedicated partner support.
