How can I set a custom HTTP header on a request sent using cURL?
We can do this using cURL’s
-H/--header flag, which allows us to specify an HTTP header to be included in the request we’re sending.
curl --header "X-MyCustomHeader: HeaderValue" sentry.io
If we need to add multiple custom headers to the request, we can do this with multiple
curl --header "X-MyCustomHeader: HeaderValue" --header "X-AnotherHeader: Value" sentry.io
To confirm that our request looks as we expect it to, we can have cURL print it out by providing the
-v/--verbose flag as well:
curl --header "X-MyCustomHeader: HeaderValue" -v sentry.io
The above command will show an HTTP request resembling the following:
> GET / HTTP/1.1 > Host: sentry.io > User-Agent: curl/8.1.2 > Accept: */* > X-MyCustomHeader: HeaderValue
More information about cURL can be found by perusing its manual page, which is accessible on the cURL website or through the command
