tweetinvi RegisterWebhookAsync 401 - Unauthorized - Authentication credentials were missing or incorrect

Question

I am trying to use TweetInvi (4.0.3) to register a webhook:

 var twitterCreditials = Auth.SetUserCredentials(twitterOptions.APIkey, twitterOptions.APISecretKey, twitterOptions.AccessToken, twitterOptions.AccessTokenSecret);

 Webhooks.RegisterWebhookAsync("mydevenv", HttpUtility.UrlEncode("https://.../webhooks/twitter"), twitterCreditials);

But I get the following exception in response:

URL : https://api.twitter.com/1.1/account_activity/all/mydevenv/webhooks.json?url=https%3a%2f%2f...%2fwebhooks%2ftwitter
Code : 401
Error documentation description : Unauthorized -  Authentication credentials were missing or incorrect.
Error message : https://api.twitter.com/1.1/account_activity/all/mydevenv/webhooks.json?url=https%3a%2f%2f...%2fwebhooks%2ftwitter web request failed.
Could not authenticate you. (32)

I've checked and double checked that my credentials are correct and I've followed the instructions here to create a dev environment. I've tried regenerating all my credentials for my Twitter app, but to no avail.

The error message suggests there is something wrong with my credentials, but I cannot see what.

I can see a log message when my webhook callback endpoint is called and it is not getting called.

I've also tried with version 5-beta of Tweetinvi:

var userClient = new TwitterClient("...", "...", "...", "...");
await userClient.AccountActivity.CreateAccountActivityWebhookAsync("mydevenv", "https://.../webhooks/twitter");

But this gives me a 400 for what appears to be the same call to the Twitter API as version 4.

There must be something simple I've missed?

You have to update user setup in your twitter project and set new permission to read/write . Go to developer portl -> project -> setting -> User authentication settings -> select read/write permission
