hello team,

I came across the issue whee i am not getting same trace id for RUM & APM transaction.

E.g. i initiate the transaction "add product to basket" and i get the transaction detail in APM (service - clothing) & RUM (service - clothing-rum) both but the transaction contains different trace id

kindly suggest what we can do to get the same trace id?

My infrastructure details as below:

Hi @pratikshatiwari,

It looks to me that you are making cross-origin requests. While the RUM agent does support distributed tracing out of the box, it only supports requests on the same origin unless you specify the cross-origin url via the [`distributedTracingOrigins `](https://www.elastic.co/guide/en/apm/agent/rum-js/current/distributed-tracing-guide.html#enable-cors) configuration. Check out the [distributed tracing guide in the docs](https://www.elastic.co/guide/en/apm/agent/rum-js/current/distributed-tracing-guide.html).

Can you check if enabling cross-origin requests fixes your issue?

Hi carly,

Thank you for your responce

i have tried setting up RUM agent with below configuration in order to enable distributedtracing from rum agent but still i dont get any improvment

RUM agent configuration as below:

##########

```auto
    <script src="~/lib/apm-rum/elastic-apm-rum.umd.min.js" crossorigin></script>
    <script>
        elasticApm.init({
            serviceName: 'clothing-rum',
            serverUrl: 'https://XX.XX.XX.XX:8200',
            SERVER_CERT: "~/lib/cert/ca.crt",
            VerifyServerCert: "false",
            environment: 'DEV',
            distributedTracingOrigins: ['https://localhost:44315', 'https://localhost:5099/*', '*']
        });
    </script>

```

Also APM Server file configuration as below:

```auto

Hi @pratikshatiwari,

this part of our doc could be useful in your case: [Public API | APM .NET Agent Reference [1.x] | Elastic](https://www.elastic.co/guide/en/apm/agent/dotnet/current/public-api.html#api-transaction-ensure-parent-id)

Hi @GregKalapos

Thank for reply yes this did helped me to get the traces of teh API from same ASP dotnet project, but not from the other project which i s a part of same microservice,

i hvae microservice project with below projects

Web - frontend - [https://localhost:1234](https://localhost:1234)  
Public API - Admin API - [https://localhost:5678](https://localhost:5678)

RUM configurations exist in Web project which have project html file but using this configuration i can't get the Public API traces running on [https://localhost:5678](https://localhost:5678)

i have the following configuration in web cshtml file

```
<script src="~/lib/apm-rum/elastic-apm-rum.umd.min.js" crossorigin="anonymous"></script>
<script>
    elasticApm.init({
        serviceName: 'clothing-rum',
        serverUrl: 'https://xx.xx.xx.xx:8200',
        "ServerCert": "~/lib/cert/ca.crt",
        "VerifyServerCert": "true",
        "Environment": "ecommerce",
        distributedTracingOrigins: ['https://localhost:1234'],
        //var transaction = agent.Tracer.StartTransaction("Transaction1", "sample");
        //transaction.SetService("clothing", "1.0-beta1");
        pageLoadTraceId: '@Elastic.Apm.Agent.Tracer.CurrentTransaction?.TraceId',
        pageLoadSpanId: '@Elastic.Apm.Agent.Tracer.CurrentTransaction?.EnsureParentId()',
        pageLoadSampled: @Json.Serialize(Elastic.Apm.Agent.Tracer?.CurrentTransaction.IsSampled),
    });
</script>

```
