How to use an API key

This topic outlines the high-level steps of how to create and use API keys.

1. Create API key credentials

API key authentication requires a set of API key credentials.

2. Copy the API key

The API key credentials created in the previous step can contain up to two API keys. These long-lived access tokens are only visible once when they are created and are not stored anywhere in ArcGIS. Copy the API key to use it in your client application.

You can get the API key access token in two ways:

Get the access token immediately:

1. When you first create API key credentials, click Generate token to create an API key. Copy the resulting string.

Get the access token after the item is created:

1. Go to the item page of your API key credentials and click Credentials > Manage.

2. Under API keys, click Regenerate API key to generate a new API key. This will invalidate the existing key.

3. Alternatively, click Generate a secondary API key to generate a second API key without invalidating the first. The two keys share identical privileges, and each has a unique expiration date.

3. Use the API key

The last step is to use the API key access token to make requests to secure resources. To use the access token, embed it directly into your application.
