Functional API, contracts and chained flows
Automated API regression suites that run on every build, written in Postman, REST Assured and k6 and maintained by us. US product teams get this work in US hours, 9am to 1pm Eastern, with delivery from India, from an ISO/IEC 17025 accredited lab with CMMI Level 3 process. REST, SOAP and GraphQL are in the work. The hub for web, mobile and API automation is test automation services.
Functional API test automation
Validate request and response integrity, payloads, status codes and business rules through automated test suites. A fail is triaged as product, test or environment, not left as a red build nobody owns.
Contract testing and schema validation
Ensure APIs adhere to OpenAPI and Swagger specs and that a change does not break downstream integrations. Schema and version compatibility sit in the suite, not in a document nobody reruns.
End-to-end workflow testing
Test chained API calls across services to verify business-critical flows like login, checkout, data sync and payments. Dependent calls are in the design, not a surprise after the first release.

Book a CallCI/CD, REST SOAP GraphQL, and what we keep unique
API testing is integrated with CI/CD so the suite runs on every build. We automate testing for RESTful services, SOAP-based integrations, and GraphQL queries and mutations. Schema validation and contract testing stay in the pack. Method depth sits in API test automation best practices 2026. Neighbouring slices: AI-powered test automation and mobile test automation.
What you get
A regression suite in Postman, REST Assured or k6 that runs on the pipeline, with contract and schema checks, and chained flows named in the design. Maintenance is in the quote. A free automation-readiness review of one test suite is the first look.
What this page is not
The full web and mobile automation hub. UI locators live there. Customer-support bots live on AI customer support automation. This URL is API test automation.
Proof from delivery
Sector and country. Coverage and issue reduction on an airline platform, and less testing time through automation on a UAE finance platform.
India · major airline · booking and check-in
Before: coverage on booking and check-in was too thin for the release pace. After two release cycles: 85% test coverage and 70% fewer customer-reported issues. The stable API journeys that sell seats ran on the pipeline.
85% test coverage 70% fewer customer-reported issuesUAE · SME finance platform
Testing time was eating the sprint. Automation on the repeatable finance journeys cut testing time by 40%. Exploratory work stayed with a person. The cadence changed because the pack ran on the pipeline.
40% less testing timeFrequently Asked Questions
AI writes some scripts. It does not own a suite that must stay green on every build. On this page that suite is API regression in Postman, REST Assured and k6, running in the pipeline, with a person who triages a fail as product, test or environment. Testers who design contracts, chained flows and maintenance stay in the work. A recording with no owner is not a replacement. The free automation-readiness review of one test suite is the first look.
Yes, for people who can keep an API suite alive in CI/CD, not only for people who click through a UI. Demand sits on contract tests, schema checks, chained workflows and the maintenance that decides whether automation pays back. Vervali runs this work in US hours, 9am to 1pm Eastern, with delivery from India, from an ISO/IEC 17025 accredited lab. The hub for the wider offer is test automation services. This page is the API slice.
It runs the checks that are stable, frequent and expensive to repeat by hand, on every build. On this page that is API regression: request and response, contracts and schema, chained flows such as login, checkout, data sync and payments, written in Postman, REST Assured and k6. A person still designs the suite and triages the red build. UI automation lives on the hub. Method depth sits in our API test automation best practices post.
We will not invent a ranked ten. On this page the tools that matter are Postman, REST Assured and k6 for API suites that run on every build. Selenium, Playwright, Cypress and Appium sit on test automation services when the surface is UI or mobile. The right tool is the one your people can maintain after handover. Judge a vendor on that, not on a logo wall. A free review of one test suite names which you need.
Judge a vendor on whether they will write API suites that run in your pipeline, maintain them, and tell you what not to automate. Ranked lists are not that. Vervali is an ISO/IEC 17025 accredited lab with CMMI Level 3 process, US-hours coverage and delivery from India. This URL is API test automation in Postman, REST Assured and k6. The hub is test automation services. We do not rank ten firms.
Same test: pipeline, maintenance, and an honest split of what stays manual. Vervali puts ISO/IEC 17025, CMMI Level 3, US hours and a free automation-readiness review of one test suite against that. We do not publish a top-ten ranking. Clutch is where buyers compare ratings. This page is the API offer. AI-powered test automation and mobile test automation are the neighbouring slices, not a catalogue of vendors.
Pay follows whether you can keep a suite green in a real pipeline, not a certificate name. API automation in Postman, REST Assured and k6 is that kind of work. We do not publish salary bands on this page. US product teams buy the service here. Delivery is from India in US hours. If the question is who you hire rather than what you buy, start with a free automation-readiness review of one test suite.
Look at one API surface, say which tests belong in Postman, REST Assured or k6, which belong in the pipeline, and which should stay manual. Then write the suite, wire it to every build, and name the maintenance. That is the free automation-readiness review of one test suite, then the engagement. It is not a slide about tools. The consultant who will not tell you what not to automate is selling coverage, not a suite you still run.
