This is my code to try to register a webhook to AAAPI and I do have a premium/sandbox account. I can use the same code, only by changing the url to “https://api.twitter.com/1.1/statuses/update.json” and add status string to update a tweet successfully, which means all my signature and tokens and secrets should be correct, right? Can somebody help me out please? thanks!
