# Build unpublish transaction data for a drop

`POST /api/v2/drops/{slug}/unpublish`

## Request

- Base URL: `https://api.opensea.io`
- URL: `https://api.opensea.io/api/v2/drops/{slug}/unpublish`
- Auth: API key in header `x-api-key` and OpenID Connect (`https://auth.opensea.io/.well-known/openid-configuration`, scopes: `write:drops`)
- TypeScript: <https://skmtc.dev/opensea/apis/opensea-api/docs/api/v2/drops/:slug/unpublish/post.ts> (a function with typed inputs; its response is checked against the schema)

Returns a ready-to-sign transaction that closes a live ERC-721 SeaDrop V1 drop by replacing its stages with one that has already ended. Only the collection owner can call this endpoint, and the transaction must be sent from `from`.

This saves that ended stage as the drop's draft before returning, replacing any edits saved with POST /api/v2/drops/{slug}. If the transaction is never sent, save new edits before publishing again.

## Path parameters

- `slug` string, required

## Response `200`

Ready-to-sign unpublish transaction

  - `data` string, required: Encoded transaction data (hex)
  - `from` string, required: Address the transaction must be sent from: the contract's onchain owner. Sent from any other address it reverts.
  - `to` string, required: Transaction target contract address
  - `value` string, required: Native currency to send with the transaction, in wei, as a decimal string (not hex)
