Loket.nl API
**Is this your first time here? Please check out our introduction to Loket (API)** **The initial loading time of this developer portal may be very long due to the large number of endpoints designs being rendered when loading the page. We are looking into an alternative solution but for now please bear in mind.** # General The Loket.nl API is a RESTful API that exposes the data and features of the Loket.nl platform. The API accepts and returns JSON and can only be accessed by registered users. This documentation describes version 2 of the API. Are you looking to partner up and start building an integration based on the Loket RESTful API? Please check out the steps for partners on our website . Have you received your client and user credentials from us? Check out the following Postman collection to help you start making your first API calls on our acceptance environment. We would recommend to install the Postman desktop app. ![Run in Postman](https://god.gw.postman.com/run-collection/19604713-42728000-2df3-4ff0-908e-dc6ab410990c?action=collection%2Ffork&collection-url=entityId%3D19604713-42728000-2df3-4ff0-908e-dc6ab410990c%26entityType%3Dcollection%26workspaceId%3Ddde2c409-9fb2-4f40
Plan the first integration safely
The access fields below come from the connected directory. Their likely implementation impact is explained without assuming provider-specific behavior.
Authentication
OAuth is reported. Confirm flows, scopes, consent, token lifetime, and refresh rules.
Transport
HTTPS is not confirmed. Do not send credentials or production data until secure transport is verified.
Browser access
CORS is unknown. Treat direct browser access as unconfirmed and test before choosing a client-only architecture.
First-request sequence
- Identify the current base URL, version, and endpoint for the use case.
- Confirm how credentials are issued and where they may be stored.
- Test success, invalid input, throttling, unavailable data, and timeouts.
- Record response fields, pagination, caching, and error shapes.
- Add monitoring, retries with backoff, and an appropriate fallback.
Questions to resolve before production
Pricing and quotas
Confirm current plans, free-tier limits, overages, and request ceilings.
Endpoint coverage
Check that the operations and response fields match the intended workload.
Reliability
Look for uptime history, a status page, support routes, and service commitments.
Data and privacy
Review retention, licensing, regional processing, and compliance requirements.
Versioning
Confirm the active version, change policy, deprecation window, and migration guidance.
Developer experience
Validate SDKs, examples, error formats, pagination, and test environments.
