block xhr requests with specific content in the header (ublock or other blocking program)

[babadoctor]

 

hi

 

i want to block xhr requests from my browser using ublock or another program like umatrix

 

https://this.website.com/api/*/test/*/specificad/*/specifictrackerrequest

 

the /specfictrackerrequest has a JSON request payload with content like...

 

foobar1:[

{

"event_type": "ad_tracker1",
 "client_timestamp": "..."

}

],

foobar2:[

{

"event_type": "ad_tracker2",
 "client_timestamp": "..."

}

],

 

 

 

in order for the website to work properly, i need to ONLY block the requests with specific words

 

 

for example, i want to block only the event types with "ad_tracker1" in them

 

Is there any easy way to do this?
