Administration API - Using the API

Jump to: navigation, search

In this chapter you can find a description of the MailStore Server Administration API. With the Administration API administrative tasks, such as managing users or storage locations, can be remote controlled from a central location. Communication with the Administration API is done using web requests through HTTPS.

For security reasons, the MailStore Server Administration API is deactivated by default and has to be activated using the MailStore Server Service Configuration. When you are connecting to the API and using a hostname other than localhost or 127.0.0.1 you have to change the password of the admin user before.

MailStore API Test Application

MailStore API Tester

To help you better understand the samples on this page, we provide a small tool that is able to send commands to the API HTTPS server and display its responses. Simply download the ZIP file provided below and run the included MailStoreApiTester.exe.

The download comes with the entire C# source code of the test application.

Executing Regular API Functions

To execute regular Management API functions, send a HTTP POST request to the following URL:

https://<mailstore-server>:8463/api/invoke/<function>

With every request to the API, the username and password of a MailStore Administrator must be submitted following the HTTP Basic Authentication specification as described in RFC 2617

Example

HTTP Request

POST /api/invoke/GetServerInfo HTTP/1.1
Authorization: Basic YWRtaW46UGFzc3cwcmQ=
User-Agent: curl/7.35.0
Host: mailstore.example.com:8463
Accept: */*
Content-Length: 0

HTTP Response

HTTP/1.1 200 OK
Cache-Control: no-cache,private,no-store,must-revalidate,max-stale=0,post-check=0,pre-check=0
Pragma: no-cache
Content-Length: 251

{
  "error": null,
  "token": null,
  "statusVersion": 2,
  "statusCode": "succeeded",
  "percentProgress": null,
  "statusText": null,
  "result": {
    "version": "9.0.0.9702",
    "machineName": "MAILSTORE"
  },
  "logOutput": null
}

To get a list of all available functions, send a POST request to https://<mailstore-server:8463/api/get-metadata.

Long Running Processes

Some API functions start a long running process that may take several minutes or even hours to complete. To keep track of the progress a unique token is returned upon initial request, which can be used to periodically poll for status updates.

The overall process is as follows:

  1. Send HTTP POST to https://<mailstore-server>:8463/api/invoke/VerifyStore in order to execute the function.
  2. Check the server's response for the keys token, statusCode and statusVersion.
  3. To retrieve status updates, send periodic requests to https://<mailstore-server>:8463/api/get-status with the following parameters:
Name Description
token The received unique token for the process.
lastKnownStatusVersion Value of statusVersion from last response.
millisecondsTimeout Time in milliseconds until the the server stops waiting for a new status update to send. If a new status update is available it will be sent to the client immediately, otherwise the last status is repeated.
4. The process finished when the statusCode is not running.

}

Error Handling

Additionally to handling protocol specific issues such as HTTP or TCP errors, developers receive detailed information from the API itself in case the request did not succeed.

In case the request was successfully be processed, the response will contain:

 "error": null

Otherwise in the event of a failure the error key will have the following structure

 "error": {
   "message": string,
   "details": string
 }

allowing developers to display a meaningful error message and further technical details.
