Activate

Please log in to get a personalized configuration!

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.

Parameters

Parameter Description Remarks
ProductId the product id required
Key the serial key string required
Sign If true, the information inside the LiceseKey object will be signed. optional. false by default.
MachineCode The machine code (a string that identifies a device) for activation. optional. empty string by default.
FriendlyName Allows you to specify a friendy name for the activated device, for example the employee's email. Friendly name does not impact the number of active machine codes / seats, but it offers an easy way of linking a machine/seat with a user. For added security, you can HMAC hash this value. optional. empty string by default.
FieldsToReturn An integer that allows you to restrict the information returned in the license key data object. optional. 0 by default = all fields returned.
SignMethod Specifies the format of the result and the way it should be signed. optional. 0 by default.
Metadata Includes additional information about the license key, such as number of activated devices, etc. optional. false by default.
FloatingTimeInterval When set to something greater than zero, floating licensing will be enabled. The time interval is then used to check that no more than the allowed number of machine codes (specified in maximumNumberOfMachines) have been activated in that time period (in seconds). Note, the machine code will have "floating:" appended in the beginning. optional. 0 by default.
MaxOverdraft When set to something greater than zero (and assuming FloatingTimeInterval is set too) floating licensing will permit a license overdraft (eg. activation will succeed even if maximumNumberOfMachines is reached). MaxOverdraft value specifies how much we can exceed the maximumNumberOfMachines value. Note, the machine code will have the following structure:
  • if concurrent devices maximumNumberOfMachines: "floating:" appended in the beginning of each machine code.
  • if concurrent devices maximumNumberOfMachines + MaxOverdraft: "floating-overdraft:" appended in the beginning of each machine code.
 optional. 0 by default.
OSInfo Additional OS related information (as a string) that will be registered as metadata in Register Event. optional. null by default.
ModelVersion The model that will be returned. In comparison to method version, this only affects what fields and information will be returned and does not impact the way the method works. A changelog can be found in the end of this page.
optional. by default, it's 1.
v Method version. optional. by default, it's 1.

Results

Parameter Description Remarks
LicenseKey A LicenseKey object. The structure is described in License Key section. If SignMethod is set to 1, the License Key will be a string representation of the object converted into base64 (all DateTime fields are expressed as 64 bit integers in Unix time). always returned
Signature The signature of the base64 representation of the LicenseKey field (above). returned if
SignMethod=1
Metadata Includes additional information about the license key, such as number of activated devices, etc. returned if
Metadata=True
Result This is either 0(=success) or 1(=error). always returned
Message The message that provides additional information about the result. If it's a successful result, either null or the new key (if using SKGL) will be returned. Otherwise, in case of an error, a short message will be returned describing the error. always returned.

License Key (FieldsToReturn=0)

Parameter Description Remarks Hide?
ProductId The ID of the product that this key belongs to. always returned
ID The ID (within the product) of the license key. depends on configuration
Key The license key string, eg. ABCDE-EFGHI-JKLMO-PQRST. depends on configuration
Created The creation date of the license key. always returned
Expires The expiration date of the license key. Note, it's optional and it's up to your program to interpret this. Please see Key's that don't expire. always returned
Period The duration of current license cycle eg. 30 days. Note, this is a static number and does not change automatically. always returned
F1 The feature 1 of the license key. always returned
F2 The feature 2 of the license key. always returned
F3 The feature 3 of the license key. always returned
F4 The feature 4 of the license key. always returned
F5 The feature 5 of the license key. always returned
F6 The feature 6 of the license key. always returned
F7 The feature 7 of the license key. always returned
F8 The feature 8 of the license key. always returned
Notes The notes field of the license key. depends on configuration
Block This will always be false. always returned
GlobalId A unique identifier of the license key. It can, for instance, be used as a "ReferencerId" when creating a data object(aka additional variables). depends on configuration
Customer The entire customer object assigned to this license key. depends on configuration
ActivatedMachines A list of Activation data. Note, if FloatingTimeInterval is zero, only machine codes registered with the node-locked licensing model will be shown. If FloatingTimeInterval is greater than zero, only the device in the MachineCode parameter will be in the list (more info). depends on configuration
TrialActivation Tells if trial activation is enabled. always returned
MaxNoOfMachines The maximum number of machines/devices that may activate this license. By setting this to 0, machine locking will be disabled and an unlimited number of devices will be able to activate the license. depends on configuration
AllowedMachines Machine codes of those devices that will be prioritized during activation. Even if the limit is achieved, these will still be activated. Note: This is a legacy field and is no longer used. depends on configuration
DataObjects A list of Data objects, additional variables associated with the license key. depends on configuration
SignDate The DateTime when this activation file was signed. always returned
Signature The signature of the all the fields above Returned if Sign=true.

Metadata (FieldsToReturn=0)

You can hide metadata by checking .
Parameter Description Remarks Hide?
ActivatedMachines The number of activated machines for this license key. depends on configuration
LicenseStatus Additional information about the license key. It contains the following:
  • IsValid - Either true or false, depending on if the license satisfies all conditions for being valid.
  • ReasonForInvalidity - if a license is invalid, this will contain the reason (an integer). This can be decoded as follows:
    • None = 0
    • Expired = 1
    • Blocked = 2
  • Trial - tells if the license is a trial, based on the feature definitions for the product
  • TimeLimited - tells if the license is a time-limited / subscription, based on the feature definitions for the product
  • TimeLeft - if the license key is time-limited, this field will contain the remaining number of days until it expires
 depends on configuration
UsedFloatingMachines The number of active floating machine codes for a specific FloatingTimeInterval. Tip: If you want to find the number of unused machines, subtract this value from maxNumberOfMachines. If overdraft is used, you need to add the maxOverdraft value to maxNumberOfMachines. depends on configuration
Signature The signature of the metadata object. Returned if sign=true.

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.
  • This method will not work if block is set to true. Instead, you will first need to Unblock it.
  • Hiding a column using the filedsToReturn does not remove the field from the result. It only removes the value of the field, for example by setting it to null.
  • (For first time use) Before you proceed with signing, please visit this page to generate your public/private key pair.
  • The SignMethod currently supports two ways of returning the license key information and signing the content.
    • Linq Sign (0) - The default option supported in the SKM Client API for .NET. Everything is returned as a JSON dictionary with a signature attached to the license key object.
    • String Sign (1) - This option is tailored for cross platform applications and is the preferred way retrieving signed versions of the license key object. The license key is converted into a json string which is later stored in base64. This is then signed using RSA 2048 with SHA256.
    Please note that in both cases, Sign has to be set to true if you want the license key to be signed.

Errors

Error
Access denied.
The input parameters were incorrect.
Could not find the product.
Could not find the key.
The key is blocked and cannot be accessed.
Cannot activate the new device as the limit has been reached.

Model Versions

This changelog list changes of the returned fields given the model version.
  1. This model has a few changes. First, we have added a Reseller object to the LicenseKey. Secondly, we have made sure that all node-locked and floating licenses are returned (unless field masking is used). We added FloatingExpires to ActivatedMachines so that you can check when the activatin was set to expire (note, this value can be overrriden when calling this method with a different FloatingTimeInterval).
  2. Add FriendlyName to ActivatedMachines in the license key.
  3. The original model.
