Write pin value via PUT using jQuery Ajax getting error: "Response for preflight does not have HTTP ok status."

Hi team,

I followed the API doc “Write pin value via PUT”

I’m using jQuery Ajax to make a PUT request as below:
url: ‘https://blynk-cloud.com/auth_token/update/V126’,
type: ‘PUT’,
data: [“1”],
contentType: ‘application/json; charset=utf-8’,
success: function () {

But getting error in browser console:
OPTIONS …auth_token/update/V126 404 (Not Found)
Failed to load …auth_token/update/V126: Response for preflight does not have HTTP ok status.

Note: The API works fine with Postman.

Please advise. Thanks.

What happens if you use http rather than https?


In the URL… did you use your auth token or left auth_token in there?
