I need a sample gRPC opentelemetry trace payload

I am looking for a way to send a open-telemetry trace payload to a deployed otel collector , this payload is to be sent on gRPC protocol.

I have been using postman rest client to send an http request with a JSON payload on the url : localhost:55681/v1/traces , is something similar possible to do with gRPC.

OpenTelemetry can use grpc or http. Encoding on grpc is protobuf. You have couple of options on http. You can send proto-json or just json. There are couple of differences between proto-json and json. Below is a sample proto-json that you can curl POST to an OpenTelemetry collector.

curl -H 'Content-Type: application/json' -X POST http://localhost:4318/v1/traces -d '$DATA'

Data is:

{
  "resourceSpans": [
    {
      "resource": {
        "attributes": [
          {
            "key": "deployment.environment",
            "value": { "stringValue": "stage" }
          },
          { "key": "service.name", "value": { "stringValue": "Foo App" } },
          { "key": "service.version", "value": { "stringValue": "v1.0.0" } },
          { "key": "telemetry.sdk.language", "value": { "stringValue": "go" } },
          {
            "key": "telemetry.sdk.name",
            "value": { "stringValue": "opentelemetry" }
          },
          {
            "key": "telemetry.sdk.version",
            "value": { "stringValue": "1.16.0" }
          }
        ]
      },
      "scopeSpans": [
        {
          "scope": { "name": "foo" },
          "spans": [
            {
              "traceId": "ba8c19fd8b342b534a8dc212573c4055",
              "spanId": "beeca1383d3dc369",
              "parentSpanId": "63087c13860db67e",
              "name": "LogOperation",
              "kind": 1,
              "startTimeUnixNano": "1697646563738900000",
              "endTimeUnixNano": "1697646563738927375",
              "links": [
                {
                  "traceId": "01000000000000000000000000000000",
                  "spanId": "0100000000000000",
                  "attributes": [
                    { "key": "one", "value": { "boolValue": true } },
                    { "key": "two", "value": { "boolValue": true } }
                  ]
                }
              ],
              "status": {}
            }
          ]
        }
      ],
      "schemaUrl": "https://opentelemetry.io/schemas/1.17.0"
    }
  ]
}

Something like the otel-cli maybe?
