# Get the API access credential of an app

> Create an app in the DingTalk Developer Console and obtain the app access_token for authentication when calling APIs.

## Step 1: Create a DingTalk app

1. Sign in to the [DingTalk Developer Console](https://open-dev.dingtalk.io/#/corpeapp).
2. Click App Development and create an internal app or a third-party enterprise app.
3. On the app details page, get the Client ID (formerly App Key/SuiteKey) and Client Secret (formerly App Secret/SuiteSecret) of the app.

## Step 2: Get the access credential of the app

Call the [Get the access token of an internal app](/open/development/obtain-the-access-token-of-an-internal-app) API or the Get the access token of a third-party app's authorized organization API to generate an access token.
