+### sendRequest
+Execute a HTTP request.  Takes a URL and an options object. This is the internally used implementation of the following shorthand functions ([post](#post), [get](#get), [put](#put), [patch](#patch), [delete](#delete), [head](#head), [uploadFile](#uploadFile) and [downloadFile](#downloadFile)). You can use this function, if you want to override global settings for each single request.
+
+The options object contains following keys:
+
+* `method`: HTTP method to be used, defaults to `get`, needs to be one of the following values:
+  * `get`, `post`, `put`, `patch`, `head`, `delete`, `upload`, `download`
+* `data`: payload to be send to the server (only applicable on `post`, `put` or `patch` methods)
+* `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
+* `timeout`: timeout value for the request in seconds, defaults to global timeout value
+* `headers`: headers object (key value pair), will be merged with global values
+* `filePath`: filePath to be used during upload and download see [uploadFile](#uploadFile) and [downloadFile](#downloadFile) for detailed information
+* `name`: name to be used during upload see [uploadFile](#uploadFile) for detailed information
+
+Here's a quick example:
+
+```js
+const options = {
+  method: 'post',
+  data: { id: 12, message: 'test' },
+  headers: { Authorization: 'OAuth2: token' }
+};
+
+cordova.plugin.http.sendRequest('https://google.com/', options, function(response) {
+  // prints 200
+  console.log(response.status);
+}, function(response) {
+  // prints 403
+  console.log(response.status);
+
+  //prints Permission denied
+  console.log(response.error);
+});
