Re-authenticating using the refresh token
Request
The initial access token is typically only valid for a short time. (The refresh token typically has a longer validity.) The client must:
- Use the refresh token to re-authenticate when the access token expires.
- When the refresh token expires, re-authenticate again.
To re-authenticate using the refresh token, send a POST request to:
https://<host>:<port>/ags/refreshHeaders
- Authorization– the refresh token that was returned during initial sign-on
- x-correlation-id– identifier for logging, to correlate messages across a call flow
- x-auth-service-id– the ID of the authentication (SSO) service to be used for authentication (mandatory)
- nv-tenant-id– the tenant ID
Mandatory arguments
- Authorization– (in header) – see above
- x-auth-service-id– (in header) – see above
- parameters– an array of parameters. These are defined in the response to the- GET /servicediscoveryrequest.
 Each member of the array is a key/value pair in the following form:CODE- { "parameters": [ { "name": "<name>", "value": "<value>" } ] }
Other arguments
None
Example
A POST request with this payload re-authenticates:
{
  "parameters": [
    {
      "name": "username",
      "value": "dave"
    }
  ]
}Note that the contents of the parameters block depend on the requirements of the SSO provider.
Response
A successful request returns an HTTP 200 status.
A bad request returns an HTTP 400 status.
An unauthorised request returns an HTTP 401 status.
A forbidden request returns an HTTP 403 status.
Example
A successful response looks like this:
