Connect with a token you delete afterwards
In Mercury, create an API token with read and write access and paste the IP whitelist Freesbe shows you. In Freesbe, click Connect under Mercury, paste the token, pick the channel and the alerts you want, and connect. Then go back to Mercury and delete the token: Freesbe used it once to add a webhook to your account and doesn't need it any more. Mercury sends each new transaction and balance change to Freesbe, signed with a secret only the two of them know.
