# Duplicate Signal

`POST /v1/signals/{signal_id}/duplicate`

## Request

- Base URL: `https://api.topo.io`
- URL: `https://api.topo.io/v1/signals/{signal_id}/duplicate`
- Auth: HTTP bearer
- TypeScript: <https://skmtc.dev/topo/apis/topo-public-api/docs/v1/signals/:signal_id/duplicate/post.ts> (a function with typed inputs; its response is checked against the schema)

Copy a signal: same preset, filters, caps and enrichment, onto a new
destination list. The copy starts active and runs a first check
immediately; the original is left unchanged. Without a `name`, the copy
is named after the source plus " (Copy)".

Requires the `signals:write` scope on the API key.
