It provides predictable URLs for accessing resources, and uses built-in HTTP features to receive commands and return responses. This makes it easy to communicate with third party systems. ## Idempotency The Debbie API supports idempotency for non-idempotent requests through the optional `Idempotency-Key` header. This ensures that retrying the same request multiple times will produce the same result, preventing duplicate operations. ### Using Idempotency Keys - Include an `Idempotency-Key` header with a unique string (we recommend UUIDs) - Maximum key length is 64 characters - Keys are valid for 48 hours - Responses served from the idempotency cache include an `Idempotency-Cached` header ### Example ```http Idempotency-Key: 123e4567-e89b-12d3-a456-426614174000 ``` ### Error Cases - Invalid key format: 400 Bad Request - Reusing a key for a different request: 400 Bad Request ### Best Practices - Use a new key for each unique business transaction - Use the same key when retrying a failed request - Store keys with request details for debugging contact: email: support@debbie.dk version: v0.1.0 x-logo: url: https://debbie-platform.github.io/platform-api-docs/deb-logo.svg servers: - url: https://api.debbiecollect.com security: - bearerAuth: [] tags: - name: Authorization description: Endpoints for interacting with authorization - name: Cases description: Endpoints for interacting with cases - name: Customers description: Endpoints for interacting with customers - name: Creditors description: Endpoints for interacting with creditors - name: Updates description: Endpoints for interacting with updates - name: Users description: Endpoints for interacting with updates - name: Files description: Endpoints for interacting with files - name: Case vouchers description: Endpoints for interacting with case vouchers - name: Billing description: Endpoints for interacting with billing - name: Links description: Endpoints for generating links - name: Webhooks description: >- Debbie provides a range of webhooks.
