Installation

npm install @gumlet/nodejs-sdk

Usage

import Gumlet from '@gumlet/nodejs-sdk';

const client = new Gumlet({
  apiKey: process.env['API_KEY'], // defaults to the API_KEY env var
});

const create = await client.videoAssets.create({
  format: 'ABR',
  collection_id: '646df1c9173a4a2fcac180b4',
  input: 'http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8',
  description: 'some description',
  tag: ['ball'],
  profile_id: '646df1c9173a4a2fcac180b7',
  cluster_type: 'prod',
  playlist_id: '6597acd5ed6f26a9c5ca9633',
  metadata: { headermeta: 'metavalue' },
  call_to_actions: [
    {
      start_time: 1,
      end_time: 90,
      text: 'some test',
      url: 'https://some-url.com',
      position_from_top: 11,
      position_from_right: 23,
      border_radius: '11',
      font_color: '#000001',
      background_color: '#ffffff',
    },
  ],
  folder: '697375fbfa2d1037283140e4',
});

console.log(create);

The examples in the following sections assume a client configured as shown above.

See the API reference for every available operation.

Authentication

Pass credentials to the generated client constructor. Environment variables are read automatically when supported by the target runtime.

| Option | Type | Default | Description | | --- | --- | --- | --- | | apiKey | string \| provider | - | Credential for the API_KEY scheme. Defaults to API_KEY. |

Declared schemes:

• API_KEY bearer token

Errors

Non-success responses throw generated API errors. Error objects expose status, headers, response body, and request metadata where the target runtime supports it.

import { APIError } from '@gumlet/nodejs-sdk';

try {
  const create = await client.videoAssets.create({
    format: 'ABR',
    collection_id: '646df1c9173a4a2fcac180b4',
    input: 'http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8',
    description: 'some description',
    tag: ['ball'],
    profile_id: '646df1c9173a4a2fcac180b7',
    cluster_type: 'prod',
    playlist_id: '6597acd5ed6f26a9c5ca9633',
    metadata: { headermeta: 'metavalue' },
    call_to_actions: [
      {
        start_time: 1,
        end_time: 90,
        text: 'some test',
        url: 'https://some-url.com',
        position_from_top: 11,
        position_from_right: 23,
        border_radius: '11',
        font_color: '#000001',
        background_color: '#ffffff',
      },
    ],
    folder: '697375fbfa2d1037283140e4',
  });
} catch (err) {
  if (err instanceof APIError) {
    console.log(err.status, err.name, err.headers);
  }
  throw err;
}

Documented error statuses: 400, 401, 403, 404, 4XX.

Client Options

Configure the generated client by setting any of these options when you create it.

import Gumlet from '@gumlet/nodejs-sdk';

const client = new Gumlet({
  timeout: 60000,
  maxRetries: 2,
  logLevel: 'debug',
});

| Option | Type | Default | Description | | --- | --- | --- | --- | | apiKey | string \| AuthTokenProvider | process.env["API_KEY"] | Credential for the API_KEY scheme. | | baseURL | string \| null | process.env["GUMLET_BASE_URL"] | Override the default API base URL. Pass null when selecting a configured environment. | | timeout | number | 60000 | Maximum time in milliseconds to wait for a response before aborting a request. | | maxRetries | number | 2 | Number of retries for temporary failures. | | defaultHeaders | HeadersInit | - | Headers sent with every request. | | defaultQuery | Record<string, string \| undefined> | - | Query parameters sent with every request. | | fetchOptions | RequestInit | - | Additional fetch options sent with every request. | | fetch | Fetch | - | Custom fetch implementation. | | logLevel | "off" \| "error" \| "warn" \| "info" \| "debug" \| null | process.env["GUMLET_LOG"] | Controls request and retry debug logging. | | logger | Logger \| null | console | Custom logger implementation. |

Request Options

| Option | Type | Default | Description | | --- | --- | --- | --- | | headers | HeadersInit | - | Per-request headers. | | query | Record<string, unknown> | - | Per-request query parameters. | | body | unknown | - | Override the generated request body. | | timeout | number | - | Per-request timeout in milliseconds. | | maxRetries | number | - | Per-request retry count. | | signal | AbortSignal | - | Abort an in-flight request. | | fetchOptions | RequestInit | - | Per-request fetch options. | | idempotencyKey | string | - | Idempotency key for retry-safe operations. Applies to this request and its retries. |

Retries and Timeouts

Generated clients support request timeouts and retry temporary failures such as network errors, 408, 409, 429, and 5xx responses. Retry delays honor Retry-After headers when present. Tune the retry and timeout client options shown above, or override them per request.

Helpers

• Use .withResponse() on any request to inspect both parsed data and the raw Response object.
• Every operation returns an APIPromise, so you can await it directly or chain .withResponse().

Logging

• Set logLevel: "debug" to log request URLs, options, response status, response headers, and retry attempts.
• Pass a custom logger to route logs into your own observability pipeline.
• Set logLevel: null to disable environment-driven logging.

Requirements

• Node.js 20+, a modern browser, or any runtime with fetch support
