API chain builder

Paste an API response, pull values out with JSONPath, and see them filled into the next request.

1Response from the first call

{
  "status": "OK",
  "result": {
    "claimSeqID": "CLM-2291",
    "amount": 12500,
    "member": { "id": 88213, "name": "A. Patil" },
    "documents": [
      { "type": "bill", "id": "DOC-17" },
      { "type": "discharge", "id": "DOC-18" }
    ]
  }
}

2Values to take out (JSONPath)

✓ CLM-2291

✓ 88213

✓ DOC-17

✓ bill, discharge

3Next request

POST /claims/${claimId}/settlement
Content-Type: application/json

{
  "memberId": ${memberId},
  "documents": ["${firstDoc}"],
  "note": "Received: ${docTypes}"
}

POST /claims/CLM-2291/settlement
Content-Type: application/json

{
  "memberId": 88213,
  "documents": ["DOC-17"],
  "note": "Received: bill, discharge"
}

Ready to send. Every ${value} in the next request was found in the response.

Try: $.result.documents[-1].idor break it — rename claimId above.

How it works

1Most API tests are a chain: call one endpoint, take an ID from the response, send it to the next one.
2Here the chain is data, not code. Change a path or a template and the result updates as you type.
3It is a small, browser-only version of the idea behind my Generic Dynamic Journey Builder.
