SDK Example Usage

Example

import { UnifiedTo } from "@unified-api/typescript-sdk";

async function run() {
    const sdk = new UnifiedTo({
        security: {
            jwt: "<YOUR_API_KEY_HERE>",
        },
    });

    const res = await sdk.accounting.listAccountingAccounts({
        connectionId: "<value>",
    });

    if (res.statusCode == 200) {
        // handle response
        console.log(res.accountingAccounts);
    }
}

run();

Server Selection

Select Server by Index

You can override the default server globally by passing a server index to the serverIdx: number optional parameter when initializing the SDK client instance. The selected server will then be used as the default on the operations that use it. This table lists the indexes associated with the available servers:

# Server Description
0 https://api.unified.to North American data region
1 https://api-eu.unified.to European data region
2 https://api-au.unified.to Australian data region

Example

import { UnifiedTo } from "@unified-api/typescript-sdk";

const unifiedTo = new UnifiedTo({
  serverIdx: 2,
  security: {
    jwt: "<YOUR_API_KEY_HERE>",
  },
});

async function run() {
  const result = await unifiedTo.accounting.createAccountingAccount({
    accountingAccount: {},
    connectionId: "<id>",
  });

  console.log(result);
}

run();

Override Server URL Per-Client

The default server can also be overridden globally by passing a URL to the serverURL: string optional parameter when initializing the SDK client instance. For example:

import { UnifiedTo } from "@unified-api/typescript-sdk";

const unifiedTo = new UnifiedTo({
  serverURL: "https://api-au.unified.to",
  security: {
    jwt: "<YOUR_API_KEY_HERE>",
  },
});

async function run() {
  const result = await unifiedTo.accounting.createAccountingAccount({
    accountingAccount: {},
    connectionId: "<id>",
  });

  console.log(result);
}

run();

Custom HTTP Client

The TypeScript SDK makes API calls using an HTTPClient that wraps the native Fetch API. This client is a thin wrapper around fetch and provides the ability to attach hooks around the request lifecycle that can be used to modify the request or handle errors and response.

The HTTPClient constructor takes an optional fetcher argument that can be used to integrate a third-party HTTP client or when writing tests to mock out the HTTP client and feed in fixtures.

The following example shows how to use the "beforeRequest" hook to to add a custom header and a timeout to requests and how to use the "requestError" hook to log errors:

import { UnifiedTo } from "@unified-api/typescript-sdk";
import { HTTPClient } from "@unified-api/typescript-sdk/lib/http";

const httpClient = new HTTPClient({
  // fetcher takes a function that has the same signature as native `fetch`.
  fetcher: (request) => {
    return fetch(request);
  }
});

httpClient.addHook("beforeRequest", (request) => {
  const nextRequest = new Request(request, {
    signal: request.signal || AbortSignal.timeout(5000)
  });

  nextRequest.headers.set("x-custom-header", "custom value");

  return nextRequest;
});

httpClient.addHook("requestError", (error, request) => {
  console.group("Request Error");
  console.log("Reason:", `${error}`);
  console.log("Endpoint:", `${request.method} ${request.url}`);
  console.groupEnd();
});

const sdk = new UnifiedTo({ httpClient });

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

Name Type Scheme
jwt apiKey API key

You can set the security parameters through the security optional parameter when initializing the SDK client instance. For example:

import { UnifiedTo } from "@unified-api/typescript-sdk";

const unifiedTo = new UnifiedTo({
  security: {
    jwt: "<YOUR_API_KEY_HERE>",
  },
});

async function run() {
  const result = await unifiedTo.accounting.createAccountingAccount({
    accountingAccount: {},
    connectionId: "<id>",
  });

  console.log(result);
}

run();

Error Handling

UnifiedToError is the base class for all HTTP error responses. It has the following properties:

Property Type Description
error.message string Error message
error.statusCode number HTTP response status code eg 404
error.headers Headers HTTP response headers
error.body string HTTP body. Can be empty string if no body is returned.
error.rawResponse Response Raw HTTP response

Example

import { UnifiedTo } from "@unified-api/typescript-sdk";
import * as errors from "@unified-api/typescript-sdk/sdk/models/errors";

const unifiedTo = new UnifiedTo({
  security: {
    jwt: "<YOUR_API_KEY_HERE>",
  },
});

async function run() {
  try {
    const result = await unifiedTo.accounting.createAccountingAccount({
      accountingAccount: {},
      connectionId: "<id>",
    });

    console.log(result);
  } catch (error) {
    if (error instanceof errors.UnifiedToError) {
      console.log(error.message);
      console.log(error.statusCode);
      console.log(error.body);
      console.log(error.headers);
    }
  }
}

run();

Error Classes

Primary error:

Less common errors (6)

Network errors:

Inherit from UnifiedToError:

  • ResponseValidationError: Type mismatch between the data returned from the server and the structure expected by the SDK. See error.rawValue for the raw value and error.pretty() for a nicely formatted multi-line string.

Requirements

For supported JavaScript runtimes, please consult RUNTIMES.md.

File uploads

Certain SDK methods accept files as part of a multi-part request. It is possible and typically recommended to upload files as a stream rather than reading the entire contents into memory. This avoids excessive memory consumption and potentially crashing with out-of-memory errors when working with very large files. The following example demonstrates how to attach a file stream to a request.

Tip

Depending on your JavaScript runtime, there are convenient utilities that return a handle to a file without reading the entire contents into memory:

  • Node.js v20+: Since v20, Node.js comes with a native openAsBlob function in node:fs.
  • Bun: The native Bun.file function produces a file handle that can be used for streaming file uploads.
  • Browsers: All supported browsers return an instance to a File when reading the value from an <input type="file"> element.
  • Node.js v18: A file stream can be created using the fileFrom helper from fetch-blob/from.js.
import { UnifiedTo } from "@unified-api/typescript-sdk";

const unifiedTo = new UnifiedTo({
  security: {
    jwt: "<YOUR_API_KEY_HERE>",
  },
});

async function run() {
  const result = await unifiedTo.passthrough.createPassthroughRaw({
    connectionId: "<id>",
    path: "/var/log",
  });

  console.log(result);
}

run();

Retries

Some of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.

To change the default retry strategy for a single API call, simply provide a retryConfig object to the call:

import { UnifiedTo } from "@unified-api/typescript-sdk";

const unifiedTo = new UnifiedTo({
  security: {
    jwt: "<YOUR_API_KEY_HERE>",
  },
});

async function run() {
  const result = await unifiedTo.accounting.createAccountingAccount({
    accountingAccount: {},
    connectionId: "<id>",
  }, {
    retries: {
      strategy: "backoff",
      backoff: {
        initialInterval: 1,
        maxInterval: 50,
        exponent: 1.1,
        maxElapsedTime: 100,
      },
      retryConnectionErrors: false,
    },
  });

  console.log(result);
}

run();

If you'd like to override the default retry strategy for all operations that support retries, you can provide a retryConfig at SDK initialization:

import { UnifiedTo } from "@unified-api/typescript-sdk";

const unifiedTo = new UnifiedTo({
  retryConfig: {
    strategy: "backoff",
    backoff: {
      initialInterval: 1,
      maxInterval: 50,
      exponent: 1.1,
      maxElapsedTime: 100,
    },
    retryConnectionErrors: false,
  },
  security: {
    jwt: "<YOUR_API_KEY_HERE>",
  },
});

async function run() {
  const result = await unifiedTo.accounting.createAccountingAccount({
    accountingAccount: {},
    connectionId: "<id>",
  });

  console.log(result);
}

run();

Debugging

You can setup your SDK to emit debug logs for SDK requests and responses.

You can pass a logger that matches console's interface as an SDK option.

Warning

Beware that debug logging will reveal secrets, like API tokens in headers, in log messages printed to a console or files. It's recommended to use this feature only during local development and not in production.

import { UnifiedTo } from "@unified-api/typescript-sdk";

const sdk = new UnifiedTo({ debugLogger: console });

Standalone functions

All the methods listed above are available as standalone functions. These functions are ideal for use in applications running in the browser, serverless runtimes or other environments where application bundle size is a primary concern. When using a bundler to build your application, all unused functionality will be either excluded from the final bundle or tree-shaken away.

To read more about standalone functions, check FUNCTIONS.md.
