Activating Flow Using Flow Tooling API

Question

I have requirement to activate flow using tooling API { Not through deployment }

I am trying to use below endpoint with body

services/data/v56.0/tooling/sobjects/Flow/{Id}

Response 
{
  "Metadata":  {
    "status": "Active"
} 
}

I am getting below Error { Please help if any one is aware }

[ { "message": "The version of the flow you're updating is active and can't be overwritten.", "errorCode": "INVALID_STATUS", "fields": [] } ]

Answer 1

Try using flowDefinition

/services/data/v57.0/tooling/sobjects/flowDefinition/3006F0000005wMkQAI

PATCH:

{ 
"Metadata": { "activeVersionNumber" : "1" }
 }

To deactivate, set activeVersionNumber to 0.

Note: While FlowDefinition's tooling API access is partially deprecated, you can still use it for Activate/Deactivate operations. If you are updating the entire metadata(along with Active status), you can use Flow with Active flag flipped on. If not, FlowDefinition is the API that you need to use.
