The API lives at https://api.ledenboek.nl/v2 and speaks JSON. With the right scopes you can:
- list, create and update members, and fetch what changed since your last sync;
- list groups and committees and add members to a group;
- list events and registrations and add registrations;
- list invoices and payments and create invoices.
An administrator of the association creates the key and chooses its scopes. A key belongs to exactly one association.
Where to start
- Quickstart: create a key, make your first request, page through members and create a member.
- Authentication: keys, scopes and test keys.
- Concepts: errors, pagination, syncing, idempotency, rate limits and versioning.
- API reference: every endpoint with its fields. The reference is built from the same OpenAPI spec that our tests check every API response against.
Building with an AI assistant?
Give it /llms.txt or the spec at /openapi.json. Both contain what it needs to write requests.
