Introduction to Coinbase Commerce

Coinbase Commerce is a service by Coinbase that enables merchants to accept cryptocurrency payments directly into their digital wallets. The Coinbase Commerce API allows you to automate this process by integrating payment options into your own platform. This guide will walk you through the key aspects of the API, including setup, authentication, and transaction handling.

1. Getting Started

Before diving into the API details, ensure you have a Coinbase Commerce account. You will need an API key to access the API. Follow these steps to get started:

1. Sign Up: Create an account on Coinbase Commerce.
2. Generate API Key: Once logged in, navigate to the API settings in your dashboard and generate a new API key. This key is required for authentication.

2. Authentication

Authentication is a crucial part of working with APIs. For Coinbase Commerce, you use an API key to authenticate your requests. Here’s how to include the API key in your requests:

• HTTP Header: Include your API key in the X-CC-Api-Key header of your request.

Example:

http
POST /v2/charges
Host: commerce.coinbase.com
X-CC-Api-Key: YOUR_API_KEY
Content-Type: application/json

{
  "name": "Test Charge",
  "description": "Test Charge Description",
  "local_price": {
    "amount": "100.00",
    "currency": "USD"
  },
  "pricing_type": "fixed_price"
}

3. API Endpoints

• Create a Charge: Initiate a new charge. This endpoint allows you to create a new payment request.

  Endpoint: /v2/charges

  Method: POST

  Required Fields:

  • name: The name of the charge.
  • description: Description of the charge.
  • local_price: Price information.
  • pricing_type: Type of pricing (e.g., fixed price).

4. Handling Responses

The API will respond with JSON objects. Here’s a brief overview of the response structure:

• Success Response:

  json
  {
    "data": {
      "id": "charge_id",
      "name": "Test Charge",
      "description": "Test Charge Description",
      "local_price": {
        "amount": "100.00",
        "currency": "USD"
      },

      "status": "created"
    }
  }

      {
        "message": "Invalid API Key",
        "type": "authentication_error"
      }
    ]
  }
  

5. Best Practices

• Security: Always secure your API key. Avoid hardcoding it in your application code. Use environment variables or secure storage solutions.
• Rate Limiting: Be aware of rate limits to avoid hitting API limits. Handle rate limit errors gracefully.
• Testing: Use the test environment provided by Coinbase Commerce before deploying to production to ensure everything works as expected.

6. Examples

Here are a few examples to illustrate common use cases:

• Creating a Charge:

  python
  import requests
  
  url = "https://commerce.coinbase.com/v2/charges"
  headers = {
    "X-CC-Api-Key": "YOUR_API_KEY",
    "Content-Type": "application/json"
  }
  data = {
    "name": "Test Charge",
    "description": "Test Charge Description",
    "local_price": {
      "amount": "100.00",
      "currency": "USD"
    },
    "pricing_type": "fixed_price"
  }
  
  response = requests.post(url, headers=headers, json=data)
  print(response.json())
  

• Retrieving a Charge:

  python
  import requests
  
  charge_id = "charge_id"
  url = f"https://commerce.coinbase.com/v2/charges/{charge_id}"
  headers = {
    "X-CC-Api-Key": "YOUR_API_KEY"
  }
  
  response = requests.get(url, headers=headers)
  print(response.json())
  

7. Troubleshooting

• Invalid API Key: Ensure that the API key is correct and has the necessary permissions.
• Rate Limit Exceeded: Check the rate limits and adjust your request frequency accordingly.
• Network Errors: Verify network connectivity and API endpoint availability.
