We received an email from Salesforce that started as follows:
You are receiving this email because you’re an admin of an org that is actively using the legacy API endpoints. Versions 21.0 through 30.0 of the Salesforce Platform SOAP, Bulk, and REST APIs are currently unsupported and you need to take action before May 2023.

I opened a support ticket to let them know that I'm the new IT Director at Coker and have no knowledge of any API use and also don't have any developers on staff who might have developed APIs. They pointed me to a report that shows the APIs that have been recently called and that report displayed the DataLoader (which is provided by Salesforce and I would hope they keep it up-to-date) and the HubSpot Connector.

Here's my question. How do I determine if something is calling "legacy" APIs or not. I don't know whether to reach out to HubSpot for help or look at something else. There were a few items in that Salesforce API report that didn't have anything in the application name column. I have no idea how to determine what those are or whether they're calling legacy APIs.
