One of the features Apideck users praise most. Pick a Unified API endpoint, switch connectors with a dropdown, authenticate as any consumer, and run a real call. No Postman collections, no SDK install, no terminal.





Generic HTTP clients see endpoints. The API Explorer sees integrations. Every form is schema-driven, every connector is one dropdown away, every response shows the raw upstream payload alongside the unified one.
Pick any Unified API endpoint, fill in the form, and hit Send. Real responses from real connectors, no Postman collections to wrangle.
Run the same call against QuickBooks, Xero, NetSuite, or Sage with one dropdown. See exactly how each connector behaves before you ship.
Every successful call generates idiomatic snippets in cURL, Node.js, Python, PHP, and .NET, pre-filled with your headers and payload.
See the unified response and the raw upstream payload side by side. Debug connector quirks without reading 200-page vendor docs.
Forms are generated from the public OpenAPI spec, so required fields, enums, and nested objects are validated before you fire the request.
Authenticate as any of your linked consumers and step into their session. Reproduce production bugs against the customer connection that actually broke.
Spin up a sandbox, link a few connectors, and run real calls in 5 minutes. No purchase order, no SDK install, no demo gating.
Switch into the consumer who reported the issue, replay the request that failed, and see the upstream response next to the unified one.
Walk a PM, support agent, or partnerships lead through a live integration without sharing API keys or pairing in a terminal.
Try the call in the browser, copy the generated code into your repo, and you are done. The form fields, required headers, and pagination are already wired up.
Postman is a great HTTP client. The API Explorer is a unified-API workbench.
Want both? Every successful call generates a curl one-liner you can paste into Postman.
Every call you run in the API Explorer comes with a generated snippet in the SDK of your choice — pre-filled with your headers, your consumer, your payload. Copy it into your repo and ship.

})Pick any endpoint across the 9+ Unified APIs (Accounting, CRM, HRIS, ATS, File Storage, Issue Tracking, ERP, POS, E-commerce), choose a connector and consumer, fill in the schema-driven form, and run a real request. The response, status, latency, and raw upstream payload show up immediately, alongside copy-paste-ready code in cURL, Node.js, Python, PHP, and .NET.
No. The API Explorer runs in your browser. Sign up for a free Apideck account, link a connector, and you are testing live calls in minutes — no Postman collection import, no SDK install, no local proxy.
Postman is a generic HTTP client — you bring the spec, the auth, the headers, and the connectors yourself. The Apideck API Explorer is purpose-built for unified-API testing: every endpoint is pre-wired, every connector is one dropdown away, and you can switch into a real linked consumer to reproduce production behavior. It is the difference between bringing your own oscilloscope and walking up to a fully instrumented test bench.
Yes. The API Explorer can authenticate as any of your linked consumers, so you can reproduce a customer bug against the exact connection that broke — without exposing tokens or pairing on a terminal.
Real. Every call hits the actual third-party API through Apideck Unify, so you see real data, real errors, and real latency. The raw upstream payload is shown next to the unified response so you know exactly what the connector returned.
Every Unified API has a public OpenAPI spec linked from our developer docs. The forms in the API Explorer are generated from those specs, so what you test in the browser matches what your code will see in production.
