I'm using Salesforce developer account and trying to obtain OAuth access token using curl and it returns 500 Server Error
giving the message specified in [1].
Used curl command is curl -v -H "Content-Type: application/x-www-form-urlencoded" -H "X-PrettyPrint:1" -d "grant_type=password&client_id=<C_ID>&client_secret=<SECRET>&username=<UN>&password=<PW>" https://login.salesforce.com/services/oauth2/token
What i conclude is, this happens because of mis-configuring Callback URL of OAuth app configurations. I cannot understand what would be intended value for that because i dont have any URL to redirect.
I have tried configuring https://login.salesforce.com/services/oauth2/success
as the Callback URL value and had no luck.
What would be the use of Callback URL setting to https://login.salesforce.com/services/oauth2/success
or what is the correct way of getting access token using curl?
Thanks in advance.
