 ## Base URLs

All API requests use HTTPS. There are two environments:

EnvironmentBase URLPurposeSandbox<https://sandbox-api.aelix.digitalapi.ai>Development and testing — no real transactionsProduction<https://api.aelix.digitalapi.ai>Live environment — real data and transactions## Request Conventions

- **Content-Type:** application/json for all request bodies
- **Accept:** application/json
- **Encoding:** UTF-8
- **Date/time:** ISO 8601 with timezone (2025-04-15T14:30:00Z)
- **Currency amounts:** Minor units (pence/cents) as integers — 2550 = £25.50
- **IDs:** Opaque strings prefixed by resource type — acc\_, pay\_, txn\_

## Response Envelope

All responses wrap data in a consistent structure:

{  
 "data": { ... }, // Resource object or array  
 "meta": { // Additional metadata  
 "request\_id": "req\_abc123",  
 "api\_version": "2025-04-01"  
 },  
 "links": { // Hypermedia links (collection responses)  
 "self": "...",  
 "next": "..."  
 }  
}

## Supported Protocols

- **REST** — JSON over HTTPS (primary)
- **AsyncAPI / Webhooks** — Event-driven push notifications
- **GraphQL** — Available on selected data APIs (beta)
