Login to Web Service

Access to the System

You need a valid coreBOS user to access the webservice interface. All the operations you can do through the REST interface will be limited by the coreBOS permission system of the connected user.

The REST API can use the users password to connect or the user's access key which is a unique identifier created for each user that can be found in the user's preferences page. This will depend on how you implement your application login screen.

The login operation establishes a session between the REST client and the coreBOS application, validates the user and returns a session identifier which must be used in all subsequent calls to coreBOS.

This login process is done in two steps, first we ask coreBOS for a challenge sequence and then we use the returned string to encode our access key for the final validation.

Get Challenge

Purpose:get a challenge string to encode the password for login
Profile:getchallenge(username:String):GetChallengeResult
Send Type:GET
Parameters:username: name of an active and valid user in coreBOS
Returns:A GetChallengeResult object with the challenge token and it's time to live
GetChallengeResult{
token:String //challenge string
serverTime:TimeStamp //time on server
expireTime:TimeStamp //expire time of token
}
URL Format:
http://corebos_url/webservice.php?operation=getchallenge&username=[username]

Login

Now that we have the challenge token we can proceed with the login step. For this we have to send the user name and a verification string. This verification string can be constructed in two ways:

  • as an md5 encrypted string of the challenge token plus the user's access key
  • as a the concatenation of the token string plus the user's password

This operation is executed as POST.

Purpose:Validate the user's access in the web service interface. The use of the getchallenge token is required
Profile:login(username:String, accessKey:String):LoginResult
Send Type:POST
Parameters:username: name of the active coreBOS user that needs access
accessKey: [token+password|md5(token+accesskey)]
Returns:A LoginResult object with the session identifier and some additional information
LoginResult{
sessionId:String //unique session identifier
userId:String //application user webserivce ID
version:String //Webservice interface version
vtigerVersion:String //coreBOS version
}
URL Format:
http://corebos_url/webservice.php?operation=login&username=[username]&accessKey=[accessKey]
Comments:The accessKey parameter is written with a capital 'K'
The user's access key can be found o nthe user's profile screen inside the application

Once these two steps have been taken we can continue by calling any of the webservice functions.

  • This method of authentication is called Challenge-Handshake Authentication Protocol and it is more secure than a username/password authentication. Read here for more information
