Website Admin Can you get an oauth token without a browser?
I have Salesforce enterprise and would like to automate some functionality of pushing data from our main system into salesforce. The issue I’m running into is getting an auth token. I can follow the pattern with a browser and it works as expected. The issue is that I don’t want to use a browser. I want my Java server to make an http call and get a call back with the token. The reason it does not work is that salesforce uses javascript redirects and cookies instead of 301 and http redirects.
I’ve seen some mention of getting a session token and then performing the operation but that will not work due to the lack of a javascript engine in my http client. Are there any alternatives in getting this to work?

For SOAP: https://developer.salesforce.com/docs/atlas.en-us.api.meta/api/sforce_api_calls_login.htm
Here's a good overview of OAuth: https://developer.salesforce.com/page/Digging_Deeper_into_OAuth_2.0_at_Salesforce.com
An autonomous client can obtain an access token by simply providing username, password and (depending on configuration) security token in an access token request. Again the request is POSTed (1) to https://login.salesforce.com/services/oauth2/token, but the payload now has the form
grant_type=password&client_id=<your_client_id>&client_secret=<your_client_secret>&username=<your_username>&password=<your_password>
The following parameters are required:
grant_type Set this to password.
client_id Your application's client identifier.
client_secret Your application's client secret.
username The API user's Salesforce.com username, of the form user@example.com.
password The API user's Salesforce.com password. If the client's IP address has not been whitelisted in your org, you must concatenate the security token with the password.
To make an http call and get a call back with the token , you need to make a Connected App in your instance and get CLIENTID and CLIENTSECRET from the connectd App.
Use this Code
Hope it will help.
