Send monthly Toggl time tracking summary via Resend email

Description This workflow fetches Toggl Track summary data for the previous month, aggregates hours per client and project, and emails a clean HTML report via Resend.

How it works 1) Compute previous month period. 2) Fetch Toggl summary (grouping=clients, subgrouping=projects). 3) Fetch clients and projects for proper names. 4) Merge and aggregate seconds to hours. 5) Generate HTML raport. 6) Send raport via Resend API.

Requirements - Toggl free account (Login, Pass, TOGGLWORKSPACEID). - Resend.com free account (RESENDAPIKEY).

Customization - Change trigger time in the Schedule Trigger node. - Modify period calculation for weekly/quarterly in Get Toggle Summary node. - Add archived projects by querying with active=false&archived=true and merging.
