Retrieves a contact.
The getContact() function returns a Promise
that resolves when the contact is found.
When a source contact is merged
with a target contact, the source contact is deleted.
When calling getContact() for a merged contact,
you can use the source or target contact ID.
In both cases, the target contact is returned.
This is supported only when calling getContact(),
and only for merged contacts.
Deleted source contact IDs are not supported on any other function.
Notes:
wixCrmBackend.getContactById().
The deprecated function will continue to work, but it will not receive updates.
To keep any existing code compatible with future changes, see the
migration instructions.suppressAuth option to true.ID of the contact to retrieve.
