To access the Antei API, all requests must be authenticated using an API key. We use Bearer Token authentication, which is passed via the Authorization header.

​
Creating an API Key

You can generate API keys from your Antei dashboard: Settings → Integrations → Create API Key There are two types of keys available:
  • Live Key – Use for real transactions in production
  • Sandbox Key – Use for testing in a non-production environment
Treat your API keys like passwords. Never expose them in public codebases or client-side code.

Sandboxhttps://sandbox.antei.com

​
Authorization Header

Add the following header to every API request: 
Authorization: Bearer YOUR_API_KEY
Make sure to replace YOUR_API_KEY with your actual key.

​
Error Handling

If your API key is missing or invalid, the API will return a:
  • 401 Unauthorized – when the token is missing or incorrect
  • 403 Forbidden – if the key doesn’t have permission for the requested resource
Ensure you’re using the correct environment-specific key and that the scopes are valid.
