Credential Definition Page

A Credential Definition is a structured list of attributes defined in the Credential Schema. Refer to the for more information about credential schemas.

Credential Definitions can be categorized into two types: self-attested and service-attested.

Self-attested means that a client fills in the information in the app to send it to a service.

Service-attested means that a credential will be created, signed, and issued to a client by the service.

After attributes have been defined in the credential schema, you need to create a credential definition.










Create Credential Definition

To create the Credential Definition, click the “Schemas” button on the main menu.

Choose the schema

Click the “My schemas” tab to use a schema intended for this service only, or click on the “Public schemas” tab to use a schema made by other services.


Click the “Create” button next to the selected schema’s name.

Trust level

Check the “Self-attested” checkbox if the data in this credential will be provided by the client personally (without previous verification by any service).

Click the “Service-attested” checkbox if this credential should be signed and issued by the service.


Select the one-off checkbox to have the client of a mobile application fill in the credential attributes each time an interaction requiring this credential is executed.

Note that this option is only accessible for self-attested credentials.


Set the authorized keys and IP prefixes for incoming credential issuing webhook requests from the third-party systems.


To configure the list of authorized IP prefixes and keys for web-hook requests to this service from third-party systems, click the "Add" button next to “Configuration of an incoming credential issuing webhook“ area.

Then, on the "Edit external web hook access" pop-up window, click “Allowed IP Prifix.“ Add allowed IP prefixes (e.g. 192.168), and choose the key type and authentication type from the drop-down lists. Note that the key type "SHA secret" can be used only in auth type "Bearer Token".

For more information about webhook and keys, see the and visit

Save Credential Definition

If all details are correct, click “Create” for create a credential definition or “Done“ for save the changes you’ve made to this credential definition.


After you have created the credential definition, please note that it cannot be deleted.


Find Credential Definition

You can find all your credential definitions in the section "My Credential Definitions" of the main menu’s "Schemas" page.

Adjust attributes metadata after Credential Definition has been created

After saving the credential definition, the credential definition's metadata can be adjusted.

Click the “Schemas” tab of the main menu, select the “My credential Definitions“ tab and choose the credential definition you want to change by clicking on it’s ID. Make all necessary changes and click “Save.“


Deprecate Credential Definition

If for any reason, you don't want the particular credential definition to be visible in the list of credential definitions, you may deprecate it.

Click on the credential definition’s name and tick the "Deprecate" checkbox on the next page.

To see ALL credential definitions in those lists again, check the "Show deprecated" checkbox on the "Schemas" page.
If a deprecated credential definition is already used for issuing credentials by your service or any other service, it will keep functioning as it previously did.




However, if you try to edit such an interaction, the system automatically removes the credentials based on a deprecated credential definition from the interaction's settings. To avoid it, tick the checkbox "Show deprecated."
