Purpose/overview:

The goal is to develop a new API in mod-finance-storage for managing information about alternative exchange rate providers. This API will handle creating, reading, updating, and deleting information, and will ensure that sensitive login details are not stored in the database.

Acceptance Criteria:

1. CRUD Operations:

   • The API must support all CRUD operations (Create, Read, Update, Delete).

2. Data Model:

   • Create a data model that includes:

     • Provider URI

     • API Key or Login (not stored in DB)

     • API Secret or Password (not stored in DB)

     • Refresh Interval (default to 1 day)

3. Single Configuration:

   • Ensure only one custom configuration per provider is allowed.

4. Security:

   • Set up secure retrieval of API Key, Login, and Password from services like AWS SSM or Vault (detailed setup will be handled separately).

5. Testing:

   • Ensure all functionalities are tested, including the correct fallback to the default provider when no custom configuration exists.
