Overview

Create an API key so your server-side applications can authenticate requests to Circle’s APIs. You can create and manage API keys in the Circle Console.

​
Prerequisites

Before you begin, ensure you have:

​
Steps

​
Step 1. Open the API & Client Keys page

Sign in to the Circle Console and select API & Client Keys from the left sidebar.

​
Step 2. Create a key

Select Create a key, then choose API Key. Enter a name for your API key and select the access level:
  • Standard: grants read/write access to all APIs, including newly introduced endpoints.
  • Restricted Access: limits the key to specific products and permission levels.
When you choose restricted access, configure the following options. Select the products the key can access: Set the permission level for each product:
  • No permission: the key cannot call any endpoints for that product.
  • Read: the key can call read-only GET endpoints.
  • Read/Write: the key can call all endpoints.
You can also add IP addresses or ranges to the IP allowlist for additional security.

​
Step 3. Copy your API key

After the Console confirms that your key was generated, select Show to reveal the key value. Copy it and store it securely. You need it to authenticate API requests.
