# Send Outreach By Kol Route

`POST /api/crm/kols/{username}/send-outreach`

## Request

- Base URL: `https://api.kolens.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://api.kolens.ai/api/crm/kols/{username}/send-outreach`
- Auth: HTTP bearer

Find-or-create a conversation for ``username`` and send the email.

Convenience endpoint for the KOL detail page's Outreach panel where
the user composes a draft against a KOL handle, not against an
existing conversation. Find-or-create on (workspace, platform,
username) so repeated sends pile up on the same conversation
timeline instead of fragmenting it.

Credits are charged by the Vercel BFF *before* it calls us — if
SendGrid rejects, we surface 502 and the BFF refunds. Keeping the
debit on the BFF side avoids cross-system distributed-transaction
pain (Supabase Postgres vs Railway Postgres are not the same DB).
