The following examples list the defined workflows. For a workflow to appear in this list, the corresponding workflow definition must be in the openidm/workflow directory:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--request GET \
"http://localhost:8080/openidm/workflow/processdefinition?_queryId=query-all-ids"

Depending on the defined workflows, the output will be something like the following:

{
  "result": [
    {
      "_id": "contractorOnboarding:1:5"
    },
    {
      "_id": "contractorOnboarding:2:9"
    }
  ],
  "resultCount": 2,
  "pagedResultsCookie": null,
  "totalPagedResultsPolicy": "NONE",
  "totalPagedResults": -1,
  "remainingPagedResults": -1
}

The following example invokes a workflow named "myWorkflow". The foo parameter is given the value bar in the workflow invocation:

curl \
--header "Content-Type: application/json" \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--request POST \
--data '{
  "_key":"contractorOnboarding",
  "foo":"bar"
}' \
"http://localhost:8080/openidm/workflow/processinstance?_action=create"
