## Create a new CNI object

`client.networkInterconnects.cnis.create(CNICreateParamsparams, RequestOptionsoptions?): CNICreateResponse`

**post** `/accounts/{account_id}/cni/cnis`

Create a new CNI object

### Parameters

- `params: CNICreateParams`

  - `account_id: string`

    Path param: Customer account tag

  - `account: string`

    Body param: Customer account tag

  - `interconnect: string`

    Body param

  - `magic: Magic`

    Body param

    - `conduit_name: string`

    - `description: string`

    - `mtu: number`

  - `bgp?: BGP`

    Body param

    - `customer_asn: number`

      ASN used on the customer end of the BGP session

    - `extra_prefixes: Array<string>`

      Extra set of static prefixes to advertise to the customer's end of the session

    - `md5_key?: string | null`

      MD5 key to use for session authentication.

      Note that *this is not a security measure*. MD5 is not a valid security mechanism, and the
      key is not treated as a secret value. This is *only* supported for preventing
      misconfiguration, not for defending against malicious attacks.

      The MD5 key, if set, must be of non-zero length and consist only of the following types of
      character:

      * ASCII alphanumerics: `[a-zA-Z0-9]`
      * Special characters in the set `'!@#$%^&*()+[]{}<>/.,;:_-~`= |`

      In other words, MD5 keys may contain any printable ASCII character aside from newline (0x0A),
      quotation mark (`"`), vertical tab (0x0B), carriage return (0x0D), tab (0x09), form feed
      (0x0C), and the question mark (`?`). Requests specifying an MD5 key with one or more of
      these disallowed characters will be rejected.

### Returns

- `CNICreateResponse`

  - `id: string`

  - `account: string`

    Customer account tag

  - `cust_ip: string`

    Customer end of the point-to-point link

    This should always be inside the same prefix as `p2p_ip`.

  - `interconnect: string`

    Interconnect identifier hosting this CNI

  - `magic: Magic`

    - `conduit_name: string`

    - `description: string`

    - `mtu: number`

  - `p2p_ip: string`

    Cloudflare end of the point-to-point link

  - `bgp?: BGP`

    - `customer_asn: number`

      ASN used on the customer end of the BGP session

    - `extra_prefixes: Array<string>`

      Extra set of static prefixes to advertise to the customer's end of the session

    - `md5_key?: string | null`

      MD5 key to use for session authentication.

      Note that *this is not a security measure*. MD5 is not a valid security mechanism, and the
      key is not treated as a secret value. This is *only* supported for preventing
      misconfiguration, not for defending against malicious attacks.

      The MD5 key, if set, must be of non-zero length and consist only of the following types of
      character:

      * ASCII alphanumerics: `[a-zA-Z0-9]`
      * Special characters in the set `'!@#$%^&*()+[]{}<>/.,;:_-~`= |`

      In other words, MD5 keys may contain any printable ASCII character aside from newline (0x0A),
      quotation mark (`"`), vertical tab (0x0B), carriage return (0x0D), tab (0x09), form feed
      (0x0C), and the question mark (`?`). Requests specifying an MD5 key with one or more of
      these disallowed characters will be rejected.

### Example

```node
import Cloudflare from 'cloudflare';

const client = new Cloudflare({
  apiToken: process.env['CLOUDFLARE_API_TOKEN'], // This is the default and can be omitted
});

const cni = await client.networkInterconnects.cnis.create({
  account_id: 'account_id',
  account: 'account',
  interconnect: 'interconnect',
  magic: {
    conduit_name: 'conduit_name',
    description: 'description',
    mtu: 0,
  },
});

console.log(cni.id);
```
