Related entities of a specific service through the environment API V2

svendb1803 — Mon, 15 Dec 2025 11:45:20 GMT

Hello

I am trying to get the related entities of a specific service via the environment api. I am using the FromRelations.Calls relationship. I have read the documentation, but unfortunately i am not able to make it work.

This is what i am trying to execute.

curl -X 'GET' \  'https://#########blanked out########/api/v2/entities?entitySelector=fromRelationships.Calls%28entityId%28SERVICE-1AAA4F%29%29' \  -H 'accept: application/json; charset=utf-8' \  -H 'Authorization: Api-Token ####blanked out####'

output is

{  "error": {    "code": 400,    "message": "Constraints violated.",    "constraintViolations": [      {
        "path": "entitySelector",        "message": "The entitySelector parameter must contain entity type information on all levels, not determinable on level with values: fromrelationships.calls",        "parameterLocation": "QUERY",        "location": null
      }
    ]
  }
}

Can someone try to help me out here with the syntax? Thank you in advance!

Hi,

I am using this and I can see relations in the output:

curl -X 'GET' \ 'https://XXXXX.live.dynatrace.com/api/v2/entities/SERVICE-XXXXX' \ -H 'accept: application/json; charset=utf-8' \ -H 'Authorization: Api-Token XXXXX'

Best regards

I haven't tested it, but it seems it wants to get type information, hence something like entityselector=type(SERVICE),fromRelationships.Calls(...) , to determine the base type it needs to query...

As mentioned, not tested but my first though...
