I am trying to get bearer key from Salesforce via postman. we have done all the connected app setting with Oauth enabling and user access.
Upon using the POST method in postman URL like https://endpoint/oauth2/token?grant_type=password&client_id=*********'&client_secret=*******&username=*****.com&password=******
I get the bearer key at times, same request returns to BAD request("error": "invalid_grant") most of the time
