Methods

Activate(String, ActivateModel)

This method will perform a key activation, similar to Activate [Web API 2]. In contrast to key validation, key activation is not read only since it can change license key data depending on configurations such as trial activation, etc. If trial activation is enabled, a key can be altered. Information that is retrieved can be signed by the server to be able to keep validate keys without Internet connection. Please keep in mind that the Feature lock can be used to restrict the fields that can be shown in the result (fieldsToReturn). More about this in Remarks. https://app.cryptolens.io/docs/api/v3/Activate

Declaration
public static KeyInfoResult Activate(string token, ActivateModel parameters)
Parameters
Type Name Description
System.String token

The access token. Read more at https://app.cryptolens.io/docs/api/v3/Auth

ActivateModel parameters

The parameters that the method needs.
Returns
Type Description
KeyInfoResult

A BasicResult or null.
Remarks

The feature lock value is used to store the filedsToReturn value. If you set a certain value in the feature lock, it will be prioritized higher than the fieldsToReturn parameter.
• To compute the value of the feature lock, please use the Hide column, for those fields that you want to omit in the result above.
• If the ActivatedMachines is hidden, only the current machine code will be included(used during this particular activation). Otherwise, all machine codes will be included.

Examples

Assuming that you've created a key in the SKM platform that has maximum number of machines set to anything greater than zero, we can run the following code:

var auth = "{access token with permission to access the activate method}"
var result = Key.Activate(token: auth, parameters: new ActivateModel()
{
    Key = "GEBNC-WZZJD-VJIHG-GCMVD",
    ProductId = 3349,
    Sign = true,
    MachineCode = SKGL.SKM.getMachineCode(SKGL.SKM.getSHA1);
});

if(result == null || result.Result == ResultType.Error)
{
    // an error occured or the key is invalid or it cannot be activated
    // (eg. the limit of activated devices was achieved)
}
// everything went fine if we are here!

Activate(String, Int32, String, String, Boolean, Int32, Int32)

This method is similar to Activate(String, ActivateModel) with the only exception that it will return a license key signed with the new protocol. Note: it's better to use this method, especially if you target Mono/Unity.
In order to get the license key, you can call FromResponse(String, RawResponse).

Declaration
public static RawResponse Activate(string token, int productId, string key, string machineCode = "", bool metadata = false, int floatingTimeInterval = 0, int maxOverdraft = 0)
Parameters
Type Name Description
System.String token
System.Int32 productId
System.String key
System.String machineCode
System.Boolean metadata
System.Int32 floatingTimeInterval
System.Int32 maxOverdraft
Returns
Type Description
RawResponse

AddFeature(String, FeatureModel)

This method will change a given feature to be true (in a license). If the key algorithm in the product is SKGL, the key string will be changed if necessary. Otherwise, if SKM15 is used, the key will stay the same. If the key is changed, the new key will be stored in the message.

Declaration
public static BasicResult AddFeature(string token, FeatureModel parameters)
Parameters
Type Name Description
System.String token

The access token. Read more at https://app.cryptolens.io/docs/api/v3/Auth

FeatureModel parameters

The parameters that the method needs.
Returns
Type Description
BasicResult

A BasicResult object or null.
Remarks

This method may, in rare cases, return null if an error has occurred. Null should be seen as an unsuccessful result.

Examples

Here is an example that demonstrates the use of the method.

public void AddFeatureTest()
{
    var keydata = new FeatureModel() { Key = "LXWVI-HSJDU-CADTC-BAJGW", Feature = 2, ProductId = 3349 };
    var auth = new AuthDetails() { Token = "WyI2Iiwib3lFQjFGYk5pTHYrelhIK2pveWdReDdEMXd4ZDlQUFB3aGpCdTRxZiJd" };

    var result = SKM.AddFeature(auth, keydata);

    if (result != null && result.Result == ResultType.Success)
    {
        // feature 2 is set to true.
    }
    else
    {
        Assert.Fail();
    }
}

BlockKey(String, KeyLockModel)

This method will block a specific license key to ensure that the key cannot be accessible by most of the methods in the Web API (activation, validation, optional field, and deactivation).Note, blocking the key will still allow you to access the key in Web API 3, unless otherwise stated for a given Web API 3 method. To do the reverse, please see UnblockKey(String, KeyLockModel).

Declaration
public static BasicResult BlockKey(string token, KeyLockModel parameters)
Parameters
Type Name Description
System.String token

The access token (https://app.cryptolens.io/User/AccessToken#/) with Block key permission.
KeyLockModel parameters

The parameters that the method needs.
Returns
Type Description
BasicResult

A BasicResult object or null.
Remarks

This method may, in rare cases, return null if an error has occurred. Null should be seen as an unsuccessful result.

ChangeNotes(String, ChangeNotesModel)

This method will change the content of the notes field of a given license key.

Declaration
public static BasicResult ChangeNotes(string token, ChangeNotesModel parameters)
Parameters
Type Name Description
System.String token

The access token (https://app.cryptolens.io/User/AccessToken#/) with Change Notes permission.
ChangeNotesModel parameters

The parameters that the method needs.
Returns
Type Description
BasicResult

A BasicResult object or null.

CreateKey(String, CreateKeyModel)

This method will create a new license key, which is the same as GenerateKey in Web API 2.

Declaration
public static CreateKeyResult CreateKey(string token, CreateKeyModel parameters)
Parameters
Type Name Description
System.String token

Details such as Token and Version.
CreateKeyModel parameters

The parameters that the method needs.
Returns
Type Description

Examples
Private Sub CreateKey()
    Dim parameters = New CreateKeyModel() With {
        .ProductId = 3,
        .F1 = 1,
        .Period = 30
    }
    Dim auth = "{access token with CreateKey permission and optional product lock}"
    Dim result = Key.CreateKey(token:=auth, parameters:=parameters)
    If (result IsNot Nothing AndAlso result.Result = ResultType.Success) Then
        ' successful
        Console.WriteLine(result.Key)
