## Create Spectrum application using a name for the origin

`client.spectrum.apps.create(AppCreateParamsparams, RequestOptionsoptions?): AppCreateResponse`

**post** `/zones/{zone_id}/spectrum/apps`

Creates a new Spectrum application from a configuration using a name for the origin.

### Parameters

- `AppCreateParams = SpectrumConfigAppConfig | SpectrumConfigPaygoAppConfig`

  - `AppCreateParamsBase`

  - `SpectrumConfigAppConfig extends AppCreateParamsBase`

  - `SpectrumConfigPaygoAppConfig extends AppCreateParamsBase`

### Returns

- `AppCreateResponse = SpectrumConfigAppConfig | SpectrumConfigPaygoAppConfig`

  - `SpectrumConfigAppConfig`

    - `id: string`

      App identifier.

    - `created_on: string`

      When the Application was created.

    - `dns: DNS`

      The name and type of DNS record for the Spectrum application.

      - `name?: string`

        The name of the DNS record associated with the application.

      - `type?: "CNAME" | "ADDRESS"`

        The type of DNS record associated with the application.

        - `"CNAME"`

        - `"ADDRESS"`

    - `modified_on: string`

      When the Application was last modified.

    - `protocol: string`

      The port configuration at Cloudflare's edge. May specify a single port, for example `"tcp/1000"`, or a range of ports, for example `"tcp/1000-2000"`.

    - `traffic_type: "direct" | "http" | "https"`

      Determines how data travels from the edge to your origin. When set to "direct", Spectrum will send traffic directly to your origin, and the application's type is derived from the `protocol`. When set to "http" or "https", Spectrum will apply Cloudflare's HTTP/HTTPS features as it sends traffic to your origin, and the application type matches this property exactly.

      - `"direct"`

      - `"http"`

      - `"https"`

    - `argo_smart_routing?: boolean`

      Enables Argo Smart Routing for this application.
      Notes: Only available for TCP applications with traffic_type set to "direct".

    - `edge_ips?: EdgeIPs`

      The anycast edge IP configuration for the hostname of this application.

      - `Dynamic`

        - `connectivity?: "all" | "ipv4" | "ipv6"`

          The IP versions supported for inbound connections on Spectrum anycast IPs.

          - `"all"`

          - `"ipv4"`

          - `"ipv6"`

        - `type?: "dynamic"`

          The type of edge IP configuration specified. Dynamically allocated edge IPs use Spectrum anycast IPs in accordance with the connectivity you specify. Only valid with CNAME DNS names.

          - `"dynamic"`

      - `Static`

        - `ips?: Array<string>`

          The array of customer owned IPs we broadcast via anycast for this hostname and application.

        - `type?: "static"`

          - `"static"`

    - `ip_firewall?: boolean`

      Enables IP Access Rules for this application.
      Notes: Only available for TCP applications.

    - `origin_direct?: Array<string>`

      List of origin IP addresses. Array may contain multiple IP addresses for load balancing.

    - `origin_dns?: OriginDNS`

      The name and type of DNS record for the Spectrum application.

        The TTL of our resolution of your DNS record in seconds.

      - `type?: "" | "A" | "AAAA" | "SRV"`

        The type of DNS record associated with the origin. "" is used to specify a combination of A/AAAA records.

        - `""`

        - `"AAAA"`

        - `"SRV"`

    - `origin_port?: OriginPort`

      The destination port at the origin. Only specified in conjunction with origin_dns. May use an integer to specify a single origin port, for example `1000`, or a string to specify a range of origin ports, for example `"1000-2000"`.
      Notes: If specifying a port range, the number of ports in the range must match the number of ports specified in the "protocol" field.

      - `number`

      - `string`

    - `proxy_protocol?: "off" | "v1" | "v2" | "simple"`

      Enables Proxy Protocol to the origin. Refer to [Enable Proxy protocol](https://developers.cloudflare.com/spectrum/getting-started/proxy-protocol/) for implementation details on PROXY Protocol V1, PROXY Protocol V2, and Simple Proxy Protocol.
