I am facing issue in connecting the angular to salesforce for getting the access token
When i try this through postman it working fine . but when i try this through angular i am getthing following error message
Access to XMLHttpRequest at 'https://bts--tnew.my.salesforce.com/services/data/v46.0/chatter/feed-elements/' from origin 'https://bts-client.herokuapp.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
here is my angular screen
Our rest of the feed is working fine when we generate access_token from postman.
but when i try to generated access_token at run time we are getting cors origin issue
Please suggest, is there any configuration i miss to configure ?
