# \[IPFS] Unpin Nid/Cid from IPFS

The following API helps you unpin an IPFS Nid from Numbers IPFS gateway. You need both the [**Capture Token**](https://docs.captureapp.xyz/about-capture/capture-account-and-wallet/capture-token) and the [**Nid**](/about/introduction/numbers-protocol/defining-web3-assets/numbers-id-nid.md) for this process. If you do not already have a Capture Token yet, please follow [the instruction](https://docs.captureapp.xyz/about-capture/capture-account-and-wallet) provided to create one.

Cost: 0.01 NUM

Method: POST

Description:
This is a free API to unpin the Nid you provide from the Numbers IPFS gateway.

This API requires a valid token for Authorization. The token should be passed in the headers of the request using the following format: "Authorization: token YOUR_CAPTURE_TOKEN"

Header:
Authorization: token $YOUR_CAPTURE_TOKEN (required)
Content-Type: application/json

Request Body (required):
nid (string): Nid to be unpinned.

Example:
curl -X POST "https://eoomqofcyr7y0fl.m.pipedream.net" \
     -H "Content-Type: application/json" \
     -H "Authorization: token YOUR_CAPTURE_TOKEN" \
     -d '{
         "nid": NID_TO_UNPIN
     }'

Response:
{
    "result": true
}

200: Nid has been successfully unpinned or Nid was not originally pinned.
400: Bad request
401: Unauthorized
403: Forbidden
500: Internal Server Error

```

{% endcode %}

A detailed explanation of the Nid can be found on the [Numbers ID (Nid) page](/about/introduction/numbers-protocol/defining-web3-assets/numbers-id-nid.md). In this example, you would replace `YOUR_CAPTURE_TOKEN` with your actual Capture token and `NID_TO_UNPIN` with the Nid you want to unpin. More examples can be found below:
