Following How to register a webhook url in Twitter? I’m trying to use the application owner access token to register my webhook url:
In Postman, I select ‘OAuth 1.0’ as authorization type, and fill out consumer key, consumer secret, token and token secret as found on the ‘Keys and Access Tokens’ tab of the app, and POST to https://api.twitter.com/1.1/account_activity/webhooks.json?url=https%3A%2F%2Fxyz.com
I get 401 with code 32: Could not authenticate you.
If I change this to GET https://api.twitter.com/1.1/statuses/mentions_timeline.json with the same authorization data, it works fine.
Is there something I misunderstand? I’m new to the Twitter API, so it may be a noob mistake.
