Hi there, I’m new to prefect and GraphQL. I’m trying to trigger a flow based on the flow_name. Is there a way to chain the following GraphQL queries or do i need to send the requests consecutively ? Thanks

query GetLatest {
  project(where: {name: {_eq: "project-test"}}) {
    flows(
      where: {name: {_eq: "flow-test"}, archived: {_eq: false}}
      order_by: {version: desc}
      limit: 1
    ) {
      id
    }
  }
}

mutation TriggerLatest {
  create_flow_run(input: {flow_id: "xxx"}) {
    id
  }
}

I think if you are using the interactive API, it only runs one at a time so you do need to chain these…but if you are using Python, there is a

StartFlowRun

task and

create_flow_run

task that do these for you here. You can also check the source here to see how it does it. These tasks will be easier than using the graphQL api in python

Hi thanks for your answer, yes I have been using the interactive api and I understand i could use the python client. But I’m designing this query for my co-workers that will run it with C#/.Net

Ah I understand. Yes exactly you’re on the right track 🙂

ok but i need to make 2 calls? : one to retrieve the id and one to trigger the flow. correct ?

Yep!

ok thanks a lot
