* `params`: query params to be appended to the URL (only applicable on `get`, `head`, `delete`, `upload` or `download` methods)
* `serializer`: data serializer to be used (only applicable on `post`, `put` or `patch` methods), defaults to global serializer value, see [setDataSerializer](#setDataSerializer) for supported values
* `responseType`: expected response type, defaults to `text`, needs to be one of the following values:
* `text` use this for all kind of text responses (e.g. JSON, XML, HTML, plain text, etc.)
* `arraybuffer` use this one for binary responses
* `text`: data is returned as decoded string, use this for all kinds of string responses (e.g. JSON, XML, HTML, plain text, etc.)
* `arraybuffer`: data is returned as [ArrayBuffer instance](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer)
* `blob`: data is returned as [Blob instance](https://developer.mozilla.org/en-US/docs/Web/API/Blob)
* `timeout`: timeout value for the request in seconds, defaults to global timeout value
* `followRedirect`: enable or disable automatically following redirects
* `headers`: headers object (key value pair), will be merged with global values
