# Publish flow

`POST /v1/whatsapp/flows/{flowId}/publish`

## Request

- Base URL: `https://zernio.com/api`
- URL: `https://zernio.com/api/v1/whatsapp/flows/{flowId}/publish`
- Auth: HTTP bearer

Publish a DRAFT flow. This is irreversible. Once published, the flow and its JSON
become immutable and the flow can be sent to users. To update a published flow,
create a new flow (optionally cloning this one via cloneFlowId).

## Path parameters

- `flowId` string, required

## Request body

- object
  - `accountId` string, required: WhatsApp account ID

## Response `200`

Flow published

- object
  - `success` boolean

## Other responses

- `400`: Flow is not in DRAFT status or has validation errors
- `401`: Missing or invalid API key. `code` is `missing_credentials` when no Authorization header was sent and `invalid_credentials` when the key is unknown, revoked or expired.
- `404`: WhatsApp account not found
