Application and User Keys

Using SAP Customer Data Cloud APIs with an Application or User Key

REST requests should be made using an application key and application secret. This is true also for requests made by third parties. Alternatively, you can use a user key and secret. These are subject to the user key's permissions and are logged for auditing purposes.

When you pass a request across HTTPS, include the site's API Key and the application key and secret (or user key and secret). For example:

 

https://...?apiKey=[SITE_API_KEY]&userKey=[APPLICATION_KEY]&secret=[APPLICATION_SECRET]

All calls should be made over HTTPS.

 

For more information about user keys, including instructions for finding your user key in the Console, see Using the User Key.

Instructional Video

If you have an SAP logon, you can watch an instructional video about managing applications here.

Creating an Application Key

You can create multiple applications, each with its own permissions, and give groups of users access to these various applications. Each application has a userKey and secret that is used when making REST calls to Gigya API Endpoints.

Another benefit of using a userKey and secret is that the user does not have to construct or check signatures, as all requests are conducted over HTTPS.

To manage your SAP Customer Data Cloud Applications:

  1. Login to the Console.
  2. Navigate to the Admin tab.
  3. Select Applications.
  4. Once on the Applications page, press Create New Application and follow the on-screen prompts.

    If you are going to use the RSA portion of the application, instead of or in addition to the userKey and secret, you MUST copy and save your RSA Private Key now. The RSA Private Key is only available inside the pop-up modal after the application is created. We do not store the RSA secret, if you do not copy it prior to closing the window, it will be necessary to generate a new key-pair. See Using an RSA Key for more information.





  5.  Once the app is created you can view the Apps userKey and secret by clicking the Edit icon, which will take you to the apps Edit Application page.



  6.  You can disseminate this userKey and secret to users whom you want to attain the privileges associated with this app. Users will use this userKey and replace the secret parameter in the request with the secret associated to this key.
  7. If at any time you want to revoke access for users using this Application, simply delete it from your account and all future attempts to use this userKey and secret will fail.

 

curl Code Example

curl https://accounts.us1.gigya.com/accounts.search 
 --data-urlencode "apiKey=3_mKxxxxXXXXXXXXxxxxxxxxXXXXxxXxxxxxxxxxxxxxxxxxxXXXXXXXXXXXXxxxxx" 
 --data-urlencode "userKey=AJxXXxXxxX2X" 
 --data-urlencode "secret=X73xXXXXXxxxxXXXxxxXXXx656767Xxx" 
 --data-urlencode "format=json" 
 --data-urlencode "query=select UID, identities.provider, identities.providerUID from accounts limit 10"

In the above example, the secret is the secret associated with the userKey, not the account secret located in the Console homepage.

 

Adding An Application Key

You can add existing applications similar to creating a new application. Simply click the Add Existing Application button and enter the userKey associated with the application, select a Permissions group to the application and press Add. If the import was successful you will get a notification (with the name of the application as it exists in the parent account):

 

It is important to note that the data associated with applications are per API key and will show blank if attempting to Edit them while viewing the Admin tab from a different API key.

 

RSA Keys

When creating a new application in the Console, a userKey and secet will be assigned to the new application. In addition, an RSA key-pair is assigned to the application. The RSA Private key is used for generating an HTTP Bearer token for use in place of the application key and secret to sign API requests.

 

The RSA Private Key is only available inside the pop-up modal when the application is created. We do not store the RSA key, so if you lose it, you will need to generate a new key-pair with a new Private key.

 

 

Using SAP Customer Data Cloud APIs with an RSA key-pair

It is possible to sign a request using an HTTP Bearer token instead of the app key and secret. Expand the link below for an example implementation using C#.

For additional information on Bearer tokens, see https://tools.ietf.org/html/rfc6750.
