I need a workflow rule that calls a webhook when a Lead is converted. At that time, I need to know the Leadid and the ContactId for the contact just created. Any idea on how to get this information, there doesn't seem to be an event for Convert and on the Create of a new Contact, the leadid is not known.

However, in the data backups, there is a file called ConvertedLeadRecords_001.csv that contains what I am looking for. Has these columns;

Convert Id

Lead/Prospect ID

Agency ID

Contact ID

Deal ID

Lead/Prospect Creation Date

Converted Time

Converted By Id
