Postman

Postman collection

Every GSTIN, PAN, HSN, monitoring, webhook, e-way bill and e-invoice request, ready to run — the same sample bodies as the docs and the API Playground.

Setup

  1. 1

    Download the collection

    Get postman-collection.json below, or import directly from the URL https://www.gstinapi.in/postman-collection.json.

  2. 2

    Import it into Postman

    Postman → Import → File (or paste the URL) → Import. You’ll see the requests grouped into folders: GSTIN, PAN, HSN/SAC, Vendor monitoring, Webhooks, E-way bill, E-invoice.

  3. 3

    Set your API key

    Open the collection’s Variables tab and set apiKey to your own key from your dashboard’s API Keys page. Every request already reads x-api-key from that variable.

  4. 4

    Send a request

    Start with "Verify a GSTIN" under the GSTIN folder — it’s pre-filled with the free test GSTIN, so it works before you touch anything else.
