# Postmark Bounce To Publisher Dnc

`POST /v1/webhooks/postmark/bounce`

## Request

- Base URL: `https://api.storyflo.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.storyflo.com/v1/webhooks/postmark/bounce`
- Auth: none declared

Stamp ``Publisher.do_not_contact=true`` on permanent Postmark
bounces so the cold-outreach pool query stops re-selecting the
address. See ``app.postmark_bounce_handler`` for categorization +
payload schema. Always returns 200 (even on auth-fail / bad-json /
DB error) so Postmark's retry queue stays clean.

## Headers

- `x-postmark-webhook-token` string, nullable

## Response `200`

Successful Response

- object

## Other responses

- `422`: Validation Error
