[Skip to content](#%5Ftop) # Manage gateways A Cloudflare Web3 gateway provides HTTP-accessible interfaces to various Web3 networks. You can interact with a gateway in several ways. ## Create a gateway * [ Dashboard ](#tab-panel-8918) * [ API ](#tab-panel-8919) To create a gateway using the dashboard: 1. In the Cloudflare dashboard, go to the **Web3** page. [ Go to **Web3** ](https://dash.cloudflare.com/?to=/:account/:zone/web3) 2. Click **Create Gateway**. 3. Enter the following information: * **Hostname**: Enter a hostname to use as your gateway, which has to be a subdomain of the current Cloudflare zone. * **Gateway Description**: Enter a description to help distinguish between different gateways. * **Gateway Type**: Select a gateway target of [IPFS DNSLink](https://developers.cloudflare.com/web3/ipfs-gateway/concepts/dnslink/), [IPFS Universal Path](https://developers.cloudflare.com/web3/ipfs-gateway/concepts/universal-gateway/), or [Ethereum](https://developers.cloudflare.com/web3/ethereum-gateway/). * **DNSLink**: Only applicable to IPFS gateways, more details at [DNSLink](https://developers.cloudflare.com/web3/ipfs-gateway/concepts/dnslink/#how-is-it-used-with-cloudflare). 1. Click **Deploy**. To create a gateway using the API, send a [POST](https://developers.cloudflare.com/api/resources/web3/subresources/hostnames/methods/create/) request that includes the following parameters: * `name`: The hostname that will point to the target gateway via a `CNAME` record. * `target`: The gateway target for the hostname (`ethereum`, `ipfs`, `ipfs_universal_path`). If you need help with API authentication, refer to [Cloudflare API documentation](https://developers.cloudflare.com/fundamentals/api/). Request ``` curl "https://api.cloudflare.com/client/v4/zones/{zone_id}/web3/hostnames" \ --header "X-Auth-Email: " \ --header "X-Auth-Key: " \ --header "Content-Type: application/json" \ --data '{ "name": "gateway.example.com", "description": "This is my IPFS gateway.", "target": "ipfs", "dnslink": "/ipns/onboarding.ipfs.cloudflare.com" }' ``` The response contains the complete definition of the new gateway. Response ``` { "success": true, "errors": [], "messages": [], "result": { "id": "", "name": "gateway.example.com", "description": "This is my IPFS gateway.", "status": "active", "target": "ipfs", "dnslink": "/ipns/onboarding.ipfs.cloudflare.com", "created_on": "", "modified_on": "" } } ``` When you create a gateway, Cloudflare automatically: * Creates and adds [records to your Cloudflare DNS](https://developers.cloudflare.com/web3/reference/gateway-dns-records/) so your gateway can receive and route traffic appropriately. * [Proxies](https://developers.cloudflare.com/dns/proxy-status/) traffic to that hostname. * Issues an SSL/TLS certificate to cover the specified hostname. --- ## Edit a gateway Once you have [created a gateway](#create-a-gateway), you can only edit the **Gateway Description** and — if it is an **IPFS** gateway — also edit the value for the [DNSLink](https://developers.cloudflare.com/web3/ipfs-gateway/concepts/dnslink/) field. If you need to edit other fields, [delete the gateway](#delete-a-gateway) and create a new one. * [ Dashboard ](#tab-panel-8910) * [ API ](#tab-panel-8911) To edit a gateway using the dashboard: 1. In the Cloudflare dashboard, go to the **Web3** page. [ Go to **Web3** ](https://dash.cloudflare.com/?to=/:account/:zone/web3) 2. On a specific gateway, click **Edit**. 3. Update the **Gateway Description** and — if editing an **IPFS** gateway — the value for the [DNSLink](https://developers.cloudflare.com/web3/ipfs-gateway/concepts/dnslink/). 4. Click **Reapply**. To edit specific settings for a gateway, use a [PATCH](https://developers.cloudflare.com/api/resources/web3/subresources/hostnames/methods/edit/) request. --- ## Refresh a gateway When your gateway is stuck in an **Error** [status](https://developers.cloudflare.com/web3/reference/gateway-status/), you should try refreshing the gateway, which attempts to re-create the associated DNS records for the hostname. * [ Dashboard ](#tab-panel-8912) * [ API ](#tab-panel-8913) To refresh a gateway using the dashboard: 1. In the Cloudflare dashboard, go to the **Web3** page. [ Go to **Web3** ](https://dash.cloudflare.com/?to=/:account/:zone/web3) 2. On a gateway, click the dropdown then **Refresh**. To refresh a gateway using the API, send a [PATCH](https://developers.cloudflare.com/api/resources/web3/subresources/hostnames/methods/edit/) request with an empty request body. --- ## Update blocklist When you set up a [IPFS Universal Path gateway](https://developers.cloudflare.com/web3/ipfs-gateway/concepts/universal-gateway/), you may want to add items to the gateway blocklist, which allows you to block access to specific content. You have the ability to block access to one or more: * CIDs (`QmPZ9gcCEpqKTo6aq61g2nXGUhM4iCL3ewB6LDXZCtioEB`) * IPFS content paths (`/ipfs/QmYwAPJzv5CZsnA625s3Xf2nemtYgPpHdWEz79ojWnPbdG/readme`) * IPNS content paths (`/ipns/example.com`) * [ Dashboard ](#tab-panel-8914) * [ API ](#tab-panel-8915) To add an item to the blocklist using the dashboard: 1. In the Cloudflare dashboard, go to the **Web3** page. [ Go to **Web3** ](https://dash.cloudflare.com/?to=/:account/:zone/web3) 2. On a specific gateway, click the dropdown then **Blocklist**. 3. Click **Add entry**. 4. Enter the following information: * **Blocklist entry type**: Choose **CID** or **Content path**. * **Blocklist entry content**: Add a CID or content path to block, meaning either a valid CIDv0 or CIDv1 string (CID) or the entry should start with `/ipfs/` or `/ipns/` (content path). * **Blocklist entry description**: Add a description to help you identify the blocklist entry. 5. Click **Add**. To add a blocklist item using the API, send a [POST](https://developers.cloudflare.com/api/resources/web3/subresources/hostnames/subresources/ipfs%5Funiversal%5Fpaths/subresources/content%5Flists/subresources/entries/methods/create/) request. --- ## Delete a gateway When you delete a gateway, Cloudflare will automatically remove all associated hostname DNS records. This action will impact your traffic and cannot be undone. * [ Dashboard ](#tab-panel-8916) * [ API ](#tab-panel-8917) To delete a gateway using the dashboard: 1. In the Cloudflare dashboard, go to the **Web3** page. [ Go to **Web3** ](https://dash.cloudflare.com/?to=/:account/:zone/web3) 2. On a specific gateway, click the dropdown then **Remove**. 3. Click **Delete hostname**. To delete a gateway using the API, send a [DELETE](https://developers.cloudflare.com/api/resources/web3/subresources/hostnames/methods/delete/) request. ```json {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/directory/","name":"Directory"}},{"@type":"ListItem","position":2,"item":{"@id":"/web3/","name":"Web3"}},{"@type":"ListItem","position":3,"item":{"@id":"/web3/how-to/","name":"How to"}},{"@type":"ListItem","position":4,"item":{"@id":"/web3/how-to/manage-gateways/","name":"Manage gateways"}}]} ```
