Here is an example how you can call an API request with a GraphQL mutation to create flow run via curl:
curl '<https://api.prefect.io>' \\
-X POST \\
-H 'content-type: application/json' \\
-H 'authorization: Bearer XXX' \\
--data '{
"query":"mutation {create_flow_run(input: { flow_id: \\"05f1872f-44b3-443a-bbd4-0a1198351cad\\" }) {id}}"
}'
Make sure to replace the ID by your flow_id
.
