extension.sendRequest()

Sends a single request to other listeners within the extension. Similar to runtime.connect, but only sends a single request with an optional response. The extension.onRequest event is fired in each page of the extension.

Syntax

chrome.extension.sendRequest(
  extensionId,             // optional string
  request,                 // any
  function(response) {...} // optional function
)

This API is also available as browser.extension.sendRequest() in a version that returns a promise.

Parameters

responseCallbackOptional

function. The function is passed the following arguments:

response

any. The JSON response object sent by the handler of the request. If an error occurs while connecting to the extension, the callback will be called with no arguments and runtime.lastError will be set to the error message.
