How can I pass parameters to a Services endpoint? I have installed Drupal 7 and enabled Services in it. I have also created an endpoint /api/v2/ and in resources, I have allowed nodes to be listed as JSON.

I have sent a GET request using browser or POSTMAN to /api/v2/node then I am getting following results.

 [
 {
 nid: "3143",
 vid: "3932",
 type: "event_calendar",
 language: "en",
 title: "EVENTS STILL APPEAR ON FRONT PAGE WHEN EVENT HAS ENDED - with or w     ithout an END DATE ",
 uid: "139",
 status: "1",
 created: "1560282811",
 changed: "1560282922",
 comment: "1",
 promote: "0",
 sticky: "0",
 tnid: "0",
 translate: "0",
 uuid: "",
 uri: "http://..../api/v2/node/3143"
 },
...
 ]`


If I send a request to http://..../api/v2/node/[nid] then I am getting an individual record of that node. 
Now I want to get post parameters to the endpoint. For example, I want to get all nodes with type = event_calendar.

I have tried posting parameters like http://..../api/v2/node?type=event_calendar but unfortunately, It is still showing list of all nodes. I have tried thing using POSTMAN and browser.
You need to use http://domain/api/v2/node?parameters[type]=event_calendar

any of the identifiers need to use inside parameters[]

Also, you can use services views module to expose the data and create new identifiers like type on your own.
