Yes, it differs a bit. There is one configuration you have to make in your Interactive Brokers account settings. Log into your Interactive Brokers account, go to Settings -> Account Reporting -> Third Party Services. Check the box next to Mint. Note the Token and Query ID being created and click Save. During the account synchronization process you will need to provide Plaid with the query ID and the token. These remain valid for 4 months and need to be renewed thereafter.
