It is possible to add a custom header to a requests call, but is there a way to make it persistent, i.e. to have the header added to every call without the need to specify it each time?

For example, to send a GET request with a custom header name, you can use the "X-Real-IP" header, which defines the client's IP address. For a load balancer service, "client" is the last remote host. Your load balancer intercepts traffic between the client and your server.
To add HTTP headers to a request, you can simply pass them in a dict to the headers parameter. Similarly, you can also send your own cookies to a server using a dict passed to the cookies parameter.
As discussed earlier, HTTP headers have a key-value pair format. The Postman JavaScript API expects both a key and a value to be provided when adding headers to the request. We can add a header by using the name: value format as a string: pm.
You can use the Session object.
The Session object allows you to persist certain parameters across requests. Sessions can also be used to provide default data to the request methods. This is done by providing data to the properties on a Session object:
s = requests.Session() s.auth = ('user', 'pass') s.headers.update({'x-test': 'true'}) # both 'x-test' and 'x-test2' are sent s.get('http://httpbin.org/headers', headers={'x-test2': 'true'})
