Hi Team,

I have a deployment in elastic cloud where I need to create multi page synthetic journey but as the web application is deployed in AWS, we have cloudflare which is blocking unwanted requests and it is blocking the synthetics journey also. May I know if it has any unique identifiers which can identify this request or any other way to complete the journey?

Note: I was trying to access public domain only.

Hi @surya_dadi_dhamarake,

Just a heads up that I've changed the topic of your question to Synthetics to ensure it's picked up correctly.

Hello, @surya_dadi_dhamarake we append string `Elastic/Synthetics` to user agent , maybe you can use that to unblock  
Example being.

`Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) HeadlessChrome/117.0.5938.62 Safari/537.36 Elastic/Synthetics`

I hope this help.  
Regards

If you are looking to whitelist Elastic IP addresses which are used in Synthetics service, that is documented here [Use Synthetics with traffic filters | Elastic Observability [8.11] | Elastic](https://www.elastic.co/guide/en/observability/current/synthetics-traffic-filters.html)

Hi @shahzad31 ,

Are those IP addresses unique per deployment and static? if those are public IP addresses which may allocate to other org also, then we cannot use whitelisting IP addresses or ranges. Can you please confirm? I will check on the ELastic/Synthetics string at the end of the request.

Thanks

They are shared with other users. You could set a custom header for your tests however by setting the `extraHTTPHeaders` playwright option in your `synthetics.config.ts`. It looks like this:

```typescript

export default env => {
  const config: SyntheticsConfig = {
    playwrightOptions: {
      extraHTTPHeaders: {
         // use whichever headers would work for your setup
        "X-My-Header": "My-Value"
      }
    },
   // rest of your config...
}

```

Hi @Andrew_Cholakian1 ,

Where can I give those headers? I cannot find synthetics.config.ts option in kibana. Can you please give me the steps to add this config for elastic cloud deployment?

I am only seeing below option in kibana.

Thanks.

Hi @surya_dadi_dhamarake,

Per @Andrew_Cholakian1's steps the headers can be specified in the _Playwright options_ section that you have in your screenshot.

Hope that helps!

So that means, I should only add this block in the playwright options.

Thanks @carly.richmond & @Andrew_Cholakian1 , That works. I can see my custom headers in the request.
