Pass parameters to Airflow Experimental REST api when creating dag run

Judging from the source code, it would appear as though parameters can be passed into the dag run.

If the body of the http request contains json, and that json contains a top level key conf the value of the conf key will be passed as configuration to trigger_dag. More on how this works can be found here.

Note the value of the conf key must be a string, e.g.

curl -X POST \
    http://localhost:8080/api/experimental/dags/<DAG_ID>/dag_runs \
    -H 'Cache-Control: no-cache' \
    -H 'Content-Type: application/json' \
    -d '{"conf":"{\"key\":\"value\"}"}'

I had the same issue. "conf" value must be in string

curl -X POST \
    http://localhost:8080/api/experimental/dags/<DAG_ID>/dag_runs \
    -H 'Cache-Control: no-cache' \
    -H 'Content-Type: application/json' \
    -d '{"conf":"{\"key\":\"value\"}"}'
