Our current API calls do have sessions expiring. However, upon attempting to re-establish a session, users are not logged in unless they first login to the TSPS GUI. This should not be a requirement to setup an API session.

Verify whether after TSPS/TSIM goes down does the application re-authenticate and get a new token or does it continue to use the same token as before?  Any non 200 or 204 return code,  should re-authenticate and try again.

 Here is the code being used which requires a new GUI login:

def login(self):
        'Returns True if success, and False if an issue'
 # Login server is  the presentation server
 
        # Re-login if our token is too old
        # FIXME: Can this be made dynamic, based on auth token?
        if self.auth_token and (time() - self.token_birthtime) < self.token_max_age:
            return 'Authenticated', 200
 
        login_url = self.sso_url + '/tsws/api/v10.1/token'
        headers = {'Content-type': 'application/json'}
        data = {'username': self.user, 'password': self.password, 'tenantName': self.tenant }
        try:
            response = self.session.post(login_url, data=json.dumps(data), headers=headers, verify=self.ssl_verify)
        except Exception as ex:
            self.log.error("TrueSight %s connection error: %s", login_url, ex)
            return str(ex),  500
 
        try:
            result = response.json()
        except Exception as ex:
            message = "Invalid data from TrueSight TSPS login() -- is primary now secondary?"
            self.log.exception(message, extra=dict(text=response.text, exception=ex))
            return message + ' ' + response.text, response.status_code
 
        message = result.get('statusMsg', response.text)
        if response.status_code != 200:
            self.log.error("TrueSight %s issue (HTTP %s): %s", self.base_url,
                response.status_code, message)
            return response.text, response.status_code
 
        # Yay! We logged in!
        self.log.info("Logged into %s successfully: %s", self.base_url, response.text)
        self.auth_token = result['response']['authToken']
        self.headers['Authorization'] = 'authtoken ' + str(self.auth_token)
        self.token_birthtime = time()
        return 'Authenticated', 200
 
    def logout(self):
        logout_url = self.sso_url + '/tsws/api/v10.1/token'
        headers = { 'authToken': self.headers['Authorization'] }
        try:
            self.session.delete(logout_url, headers=headers)
        except Exception:
            pass
        self.auth_token = None
        self.headers['Authorization'] = ''
 
        self.log.info("Logged out")
        return 'Logged out', 200
 
 
 

The following code snippet shows the correct way to use the REST API to get a token and from the login rest endpoint:
