Kintone Proxy

Kintone Proxy - kintone.proxy()

This API makes requests to external APIs. CORS errors (External link) can be avoided by using this API.

Function

kintone.proxy(url, method, headers, data, callback, errback)

Parameters

PARAMETER VALUE REQUIRED DESCRIPTION
url String Yes The request URL.
method String Yes The HTTP method. Specify one of the following: GET / POST / PUT / DELETE.
headers Object Yes Specify the request header as an object. To ignore this parameter, input {}.
Sample: { 'Content-Type': 'application/json' }
data Object or String Yes The data that will be sent in the request.To ignore this parameter, input {}.
Applied only for POST/PUT requests. Ignored for GET/DELETE requests.
For GET/DELETE requests, set the parameter on the QueryString of the URL instead.
callback Function Optional The callback function that will run once the request to the other end of the proxy has finished. It will receive the response body (string), the status code (number) and the response header (object) as parameters from the external API.

If ignored, a kintone.Promise object will be returned that can be fulfilled with an array containing a Response body (string), Status code (number) and Response header (object).
errback Function Optional The callback function that will run when the API request to the other end of the proxy fails. It will receive the response body (string) as the parameter from the external API.
If the callback is ignored, a kintone.Promise object will be returned that can be fulfilled with the Response body (string) from the proxy API.

Response

A kintone.Promise object will be returned if the callback parameter is ignored. Otherwise, there will be no response.
