Overview
Postman Echo is a public HTTP echo service. Use this client-modeREST_API connector to prove MQTT-to-HTTP wiring (methods, path placeholders, headers, cookies, status codes, and response topics) without an API key.
Basic Syntax
Events
Auth
None required. Base address ishttps://postman-echo.com. Optional Bearer token is a placeholder only. Prefer GET SECRET if you later point the connector at a private echo. Never commit real tokens.
Try it
- Add the connector on a lab broker (
-addRoutewith the LoT above). - Publish
{}tointegrations/postman-echo/request/Get. - Subscribe to
integrations/postman-echo/response/Get. Postman Echo echoes the request as JSON. - Status check: publish
{"code":"200"}tointegrations/postman-echo/request/Statuscode. - POST/PUT: publish a JSON body to
integrations/postman-echo/request/Postor.../Put. The connector sends it as{payload}.
Direct HTTP check:
GET https://postman-echo.com/get returns HTTP 200. A broker MQTT round-trip was not run for this template.
