Finds the Salesforce Contact or Lead with an email address. A Contact is returned in contact, a Lead in lead, along with all of its synced fields and salesforceURL.

Pass withRelatedObjects=true to also get the record's Account, Opportunities, most recent Events and the most recent open and closed Tasks. Events, open Tasks and closed Tasks each return up to 11 records, with hasMore and a listLink to the full list in Salesforce.

By default the lookup reads Mixmax's synced copy of your Salesforce data. Pass fetch to look the email up in Salesforce directly instead. That is slower, and fails with 500 if Salesforce can't be reached.

Requires a personal API token whose user is connected to Salesforce.
