About Adyen API

The Adyen Payment API is a comprehensive set of endpoints designed to facilitate various payment operations on the Adyen payments platform. This API enables businesses to initiate, settle, and modify payments, supporting a wide range of payment methods including card payments (with features like One-Click and 3D Secure), bank transfers, and e-wallets.

Key features of the Adyen API include:

1. Versatile payment processing: Handles authorizations, captures, cancellations, and refunds.
2. Multi-method support: Accommodates various payment methods to cater to diverse customer preferences.
3. Security features: Implements 3D Secure and 3D Secure 2 for enhanced transaction security.
4. Flexible operations: Allows for partial captures, multiple refunds, and authorization adjustments.
5. Custom references: Supports operations using merchant-defined references for easier reconciliation.

The API is designed for what Adyen calls a "Classic integration," providing developers with granular control over the payment flow. It's particularly useful for businesses requiring complex payment scenarios or those looking to build a fully customized payment experience.

Getting Started

To begin using the Adyen Payment API, follow these steps:

1. Set up an Adyen account:
   • Visit the Adyen website and sign up for an account if you haven't already.
   • Once approved, you'll gain access to the Adyen dashboard.
     
     
2. Create API credentials:
   • Log in to your Adyen dashboard.
   • Navigate to "Developers" > "API credentials".
   • Click "Create new credential".
   • Select "Web service user" as the credential type.
   • Name your credential and assign the necessary roles (e.g., Payments API).
   • Save the generated API key and username securely.
     
     
3. Choose your environment:
   • Start with the TEST environment for development and testing.
   • The production environment should only be used when you're ready to process real transactions.
     
     
4. Authentication:
   • Use Basic Authentication with your web service user credentials.
   • Example curl command:
     curl -U "ws@Company.YourCompany":"YourWsPassword" \ -H "Content-Type: application/json" \ ...
     
     
5. Make your first API call:
   • Start with a simple call, like the /authorise endpoint.
   • Construct your request payload according to the API documentation.
   • Send the request to the appropriate endpoint URL.
     
     
6. Handle the response:
   • Parse the JSON response from Adyen.
   • Check for the resultCode to determine the outcome of your request.
     
     
7. Implement error handling:
   • Prepare to handle various HTTP status codes and error messages.
   • Implement proper logging for troubleshooting.
     
     
8. Test thoroughly:
   • Use Adyen's test card numbers and other test payment method details.
   • Simulate various scenarios (successful payments, refunds, errors, etc.).
     
     
9. Implement additional features:
   • Gradually add more complex operations like 3D Secure, recurring payments, etc.
     
     
10. Go live:
    • Once testing is complete, generate new credentials for the live environment.
    • Update your integration to use the live endpoints and credentials.
    • Perform final end-to-end testing in the live environment with real payment methods.

How to use it

Fork the Adyen APIs environment and configure the variables you need: Merchant Account, Balance Account (for Platforms), etc..

VERY IMPORTANT: fork it in a PRIVATE workspace. Keep your credentials, tokens and sensitive data private.
