ⓘ Note: If your institution's account has moved to the new Infobase Platform, please visit our new Help Center for the most up-to-date documentation and support.

Note: The SUSHI base URL has changed in 2025 to accommodate the new COUNTER 5.1 standards. The new URL ishttps://connect.liblynx.com/sushi/r51which provides data back to January 2025. Your Requestor ID and Client ID will remain the same. Please contact support@infobase.com with any questions or concerns.

SUSHI

SUSHI (Standardized Usage Statistics Harvesting Initiative) is an ANSI/NISO standard API for harvesting resource usage data, and is specifically designed to work with COUNTER reporting. Technical background on SUSHI can be found on the NISO website.

Infobase, through its partnership with LibLynx, is fully COUNTER compliant and is listed in the online registry of COUNTER Compliant Platforms. Infobase supports COUNTER 5.1 report formats along with offering SUSHI harvesting.

Accessing SUSHI

1. Log into the Admin Portal with administrator credentials.

2. Click Reports in the lefthand menu, then COUNTER Reports.*

3. Click the SUSHI arrow in the upper right.


*If you do not see the COUNTER option in the reports tab, go to the Account Settings page, edit the "Admin Portal Settings," and click "Display COUNTER Reports", then Save:

Once enabled, three key pieces of information are available. These pieces of information are needed to integrate the LibLynx COUNTER reports into the reporting software. Other SUSHI fields can be left blank without affecting the transfer:

  • SUSHI Base URL (R51): The base URL for the 5.1 SUSHI API. The value is the same for all customers: https://connect.liblynx.com/sushi/r51 which provides data from January 2025. Your SUSHI service will use this base to construct the API call to get your requested report.
    • SUSHI Base URL (R5) is also shown here. This is the base URL for the 5.0.3 SUSHI API and provides data only through July 1, 2025.
  • Requestor ID/API Key: An account-specific value which grants access to the reports. Requestor ID and API Key are the same value in our system.
  • Customer ID: The LibLynx ID for your account. This will not match your Infobase customer ID.

Note: If there is no usage in the account, you will not be able to activate the SUSHI reports. You can contact support@infobase.com for assistance, or create some usage by logging into the user platform and using the materials (read articles/watch videos), then check the Admin Portal in 24 hours.

If there is no usage within a particular month, the report will return with the error message "No usage available for requested dates." Different harvesting platforms may not show the message, so you may wish to check if there is usage in the Admin Portal if you are getting no results or an error.

Testing

  • To see the records returned, try this SUSHI format URL, with your Requestor ID in both the &requestor_id= field and the &api_key= field, and your customer ID as the &customer_id=. Adjust the dates as needed (format yyyy-mm).
    • https://connect.liblynx.com/sushi/r51/reports/pr?begin_date=2025-01&end_date=2025-01&requestor_id=*****&customer_id=****&api_key=****
    • If it says "report queued for processing," wait 5 minutes and reload the page.
  • NISO recommends various services for testing SUSHI found here.
  • It is also possible to test with a SOAP testing tool like SoapUI.
