Workflow API Callout Error from Postman
I’m currently working on triggering a workflow through the Apache Hop REST API
using Postman, but I’m encountering the following issue:
<?xml version="1.0" encoding="UTF-8"?>
<webresult>
<result>ERROR</result>
<message>The specified workflow [null] could not be found</message>
<id/>
</webresult>
Below are the details of my setup:
Hop version 2.15.0
Hop Server Host: localhost
Port: 8080
Run Configuration: local
API Endpoint Used: /hop/workflows/add
Payload (XML):
<workflow_execution_configuration>
<filename>C:/Users/shiva/filename.hwf</filename>
<run_configuration>local</run_configuration>
<log_level>BASIC</log_level>
<safe_mode>N</safe_mode>
<clearing_log>N</clearing_log>
<expanding_remote_job>N</expanding_remote_job>
<gathering_metrics>N</gathering_metrics>
</workflow_execution_configuration>
I’ve verified that:
The file path is correct and accessible.
The Hop Server is running and reachable from the browser
(http://localhost:8080/hop/status).
Other endpoints (like /hop/status) return expected responses.
Despite this, the API call continues to return the “workflow [null] could not
be found” error.
