Twitter direct message API 1.1 is working from postman but not from Salesforce. Other 2.0 APIs are working but only DM is 1.1 and it’s giving an authorization error. In case anyone faced similar issue, please share your findings.
Thanks in advance.

If you have “Essential” Access, you only have access to v2 APIs. You need “Elevated” for v1.1 APIs, but if it’s working from Postman it should work elsewhere - but check that you’re using an Access token & secret, not a bearer token. DM endpoints require user context.
