extension.sendRequest()

Warning: This method has been deprecated. Use runtime.sendMessage instead.

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

Syntax

js
chrome.extension.sendRequest(
  extensionId,             // optional string
  request,                 // any
  (response) => {/* … */}  // optional function
)

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

Parameters

extensionId Optional

string. The extension ID of the extension you want to connect to. If omitted, default is your own extension.

request

any.

responseCallback Optional

function. The function is passed these 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.

Browser compatibility

Note: This API is based on Chromium's chrome.extension API. This documentation is derived from extension.json in the Chromium code.
