I have been trying to implement OAuth in Rest API.
Please note that I don't have web app(in which I can use redirect URL)
Only Backend - REST api

With all the oauth Authentication types, it is confusing to follow which one is the best to do.?
Which curl commands helps me authenticating with Zendesk successfully using oauth

Is the password grant type best suited for this type with below curl command? or what alternatives we have ?

curl https://{subdomain}.zendesk.com/oauth/tokens \
  -H "Content-Type: application/json" \
  -d '{"grant_type": "password", "client_id": "{your_client_id}", 
    "client_secret": "{your_client_secret}", "scope": "read",
    "username": "{zendesk_username}", "password": "{zendesk_password}"}' \
  -X POST
