# Delivr Merchant API > The Delivr Merchant API lets retailers quote and book same-day deliveries (on demand, a driver now, or in a service window) from their checkout, report when goods are ready, cancel, and receive signed webhooks. - Base URLs: sandbox `https://driver-staging-api.delivr.no`; production is given at onboarding. All routes are under `/v1/merchant/`. - The machine-readable contract is the OpenAPI 3.1 document at https://docs.delivr.no/openapi.yaml (webhooks included). Prefer it over prose for field names and types. - Auth: `Authorization: Bearer dmk_...` (server-side only). Every write except `POST /v1/merchant/quotes` needs an `Idempotency-Key` UUID header. - Money is integer minor units (øre), VAT included. Times are RFC 3339. Request bodies are strict: unknown fields are rejected. - Every guide page is also plain Markdown: drop the trailing slash and add `.md`, e.g. https://docs.delivr.no/quickstart.md. ## Documentation Sets - [Abridged documentation](https://docs.delivr.no/llms-small.txt): a compact version of the documentation for Delivr Merchant API, with non-essential content removed - [Complete documentation](https://docs.delivr.no/llms-full.txt): the full documentation for Delivr Merchant API ## Notes - The complete documentation includes all content from the official documentation - The content is automatically generated from the same source as the official documentation ## Optional - [OpenAPI 3.1 document](https://docs.delivr.no/openapi.yaml): Every route, schema, error code and webhook.
