# Update a checklist

`PUT https://api.gleap.io/v3/engagement/checklists/{checklistId}`

Update an engagement checklist. Any pending (not yet sent) deliveries for this engagement are discarded and re-queued from the updated document. While an engagement is live, its audience, targeting and scheduling fields cannot be changed (for `fixed` frequency engagements neither can its content); pause it first or the request fails with 409. Setting `status` to `live` starts delivery. `type`, `project`, `organisation` and `createdBy` are set server-side and ignored if supplied.

## Authorization

- `Authorization` (header, required): `Bearer <token>`

## Path parameters

- `checklistId` (string, required)

## Headers
