Configuring KanBo app

If you want to use KanBo API via KanBo.Client.dll you have to first configure your KanBo app. Inside web.config file in section <kanbo><authentication> you have to register X509 certificate that will be used for authentication (you can even generate it by yourself using makecert, see CreateCert.ps1 in Api Sample) .

Provider types for certificates

As shown above, there are different provider types for certificates:

  • AppSingedLogin” – when using this provider type your service will be seen as user which login you provide and will have exactly same permissions as that user.

On-prem login will look like this: `i:0#.w|domain\user` `domain\user`
O365 login will look like this `i:0#.f|membership|` ``


<provider id=”login” type=”AppSignedLogin”>{signer}</provider>

  • AppSignedUser” – when using this provider type your service will be seen as user defined by you in code and will have exactly same permissions as that user.


<provider id=”user” type=”AppSignedUser”>{signer}</provider>

  • AppSignedService” – when using this provider type your service will be seen as Service and will have permissions defined by KanBo – full access to everything on KanBo.


<provider id=”app” type=”AppSignedService” name=”Test service”>`{signer}</provider>


The `signer` declares which certificate will be used to validate the signature of given token, possible types are:

**X509SignerFromFile** – contains a public or private key read from a file by specified path (you can use either .cer or .pfx here, pfx file will need a key).

<signer type=”X509SignerFromFile” file=”c:\.ssl\kanbo_id.pfx” key=”MyKanBo” /> <signer type=”X509SignerFromFile” file=”c:\.ssl\kanbo_id.cer” />

**X509SignerFromStore** – contains a public or private key read from a certificate in given certificate store by specified property.

<signer type=”X509SignerFromStore” storeName=”My” storeLocation=”CurrentUser” key=”Thumbprint” value=”A89369E6705C2B3E446AF5DD5A2A1B559F913152″ />

<signer type=”X509SignerFromStore” storeName=”My” storeLocation=”LocalMachine” key=”Thumbprint” value=”a89369e6705c2b3e446af5dd5a2a1b559f913152″ />

<signer type=”X509SignerFromStore” storeName=”My” storeLocation=”LocalMachine” key=”Thumbprint” value=”a8 93 69 e6 70 5c 2b 3e 44 6a f5 dd 5a 2a 1b 55 9f 91 31 52″ />

<signer type=”X509SignerFromStore” storeName=”My” storeLocation=”LocalMachine” key=”SerialNumber” value=”a89369e6705c2b3e446af5dd5a2a1b559f913152″ />

<signer type=”X509SignerFromStore” storeName=”My” storeLocation=”LocalMachine” key=”SubjectName” value=”MyFancyApp” />


Parameters required for KanBo API object creation:

  • kanboUrl – base url of KanBo web (example: “https://kanboapp.developer.local”)
  • instanceId – id of an KanBo instance (only for KanBo versions lower than 2.7)
  • userId – id of a user our service will impersonate (only for userToken). Example: 1
  • loginName= login of kanbo user  – required for login type security token. Example: “i:0#.w|developer\\administrator”
  • certificatePath – path for the certificate that was registered in KanBo web.config
  • certificatePassword – password to certificate mentioned above
  • duration– it will define for how long the token is valid (after that it’s re-issued)
    – it’s suggested to use the default value, however if your clocks are synchronized, if not, you may consider using [special tokens that synchronize your client with server](

    • UserToken – if we want our app to work as signed user (AppSignedUser provider)
    • ServiceToken – if we want our app to work as signed service (AppSignedService provider)
    • LoginToken – if we want our app to work as signed user (AppSignedLogin provider)
    • MobileToken

Creating API object

To create our KanBo API object first we need to create a security token. There are several types of tokens.

Types of tokens

Here are examples of how to create all token types:

  • Generating token for user scope
var loginToken = new LoginToken(KanBoIssuers.Login, loginName, TimeSpan.FromMinutes(10), userCer);
  • Generating token for user scope
var userToken = new UserToken(KanBoIssuers.User, userId, TimeSpan.FromMinutes(10), userCer);
  • Generating token for service scope
var serviceToken = new ServiceToken(KanBoIssuers.Service, TimeSpan.FromMinutes(10), userCer);
  • Generating mobile token
var mobileToken = new MobileTokenSource("administrator", "adminpassword", "https://kanboapp.developer.local");

API Requester object

Next, there is a need to create a requester object for our API.


var jsonRequester = new JsonApiRequester(mobileToken, kanboUrl, httpClient);

Create API Object using a chosen requester

The last step is to create API object with use of a chosen requester:

  • Creating API object
var api = new Api(jsonRequester);

  • creating uploader object for file upload
var uploader = new Uploader(kanboUrl, jsonRequester);

Calling methods

All methods in our API can be called in the following manner:

  • Get Groups in a Board
var groups = await api.GetData(KanBoGetDataMethods.GroupsInBoard, new { BoardId = 2 });
  • Get information about this KanBo API methods arguments
var info = await api.GetMethodInfo(KanBoGetDataMethods.Board);
  • Get current user
var usr = await api.GetData(KanBoGetDataMethods.CurrentUser, new { });
  • Getting a board
 var board = await api.GetData(KanBoGetDataMethods.Board, new { Id = 2 });
  • Uploading a file to Board and attaching it to card
 await Upload(145, uploader, api);

Available methods

There are 2 types of KanBo API methods:

– GetData methods

– Actions methods
