# Reference index

[larsggu.me](https://larsggu.me/) › Reference

Every entry in the reference, listed alphabetically with the topic it belongs to. The topic groupings repeat below the table for readers who arrived from a category link.

*Twelve entries, alphabetical by term.*

| Term | Topic | Summary | Last modified |
|---|---|---|---|
| [API versioning](https://larsggu.me/reference/api-versioning) | Data shape | The mechanism by which an interface changes without breaking the callers already written against it, and the definition of which changes require it. | 2026-09-06 |
| [audit event](https://larsggu.me/reference/audit-event) | Data shape | An append-only record of who did what to which object and when, written for later reconstruction rather than for debugging. | 2026-09-06 |
| [cursor pagination](https://larsggu.me/reference/cursor-pagination) | Transport | Paging through a collection with an opaque position marker rather than a numeric offset, so that concurrent writes do not cause rows to be skipped or repeated. | 2026-09-06 |
| [error envelope](https://larsggu.me/reference/error-envelope) | Data shape | A single response shape for every failure, so that a caller can write one handler rather than one per endpoint. | 2026-09-06 |
| [idempotency key](https://larsggu.me/reference/idempotency-key) | Transport | A caller-supplied identifier that lets a request be repeated safely, because the server records the outcome against the key and replays it instead of acting twice. | 2026-09-06 |
| [OAuth 2.0 authorization code](https://larsggu.me/reference/oauth2-authorization-code) | Identity | The OAuth 2.0 flow used when a human authorises an application to act on their behalf, exchanging a short-lived code at the authorisation server for a token. | 2026-09-06 |
| [OAuth 2.0 client credentials](https://larsggu.me/reference/oauth2-client-credentials) | Identity | The OAuth 2.0 flow for machine-to-machine access, in which the application authenticates as itself with no user present and no user consent involved. | 2026-09-06 |
| [rate limit headers](https://larsggu.me/reference/rate-limit-headers) | Transport | The response headers by which a service tells a caller how much of its quota is left and when it resets, so the caller can pace itself rather than discover the limit by being refused. | 2026-09-06 |
| [SAML single sign-on](https://larsggu.me/reference/saml-single-sign-on) | Identity | A browser-mediated exchange in which an identity provider issues a signed statement about a user and the application accepts it in place of its own login. | 2026-09-06 |
| [SCIM provisioning](https://larsggu.me/reference/scim-provisioning) | Identity | A published HTTP schema, RFC 7644, by which an identity provider creates, updates, deactivates and groups accounts in an application without anyone administering them by hand. | 2026-09-06 |
| [tenant isolation](https://larsggu.me/reference/tenant-isolation) | Operations | The guarantee that one customer's data in a shared system cannot be read, written or inferred by another, enforced at the query layer rather than in application logic. | 2026-09-06 |
| [webhook delivery](https://larsggu.me/reference/webhook-delivery) | Transport | An outbound HTTP request a service makes to a customer-supplied URL when an event occurs, replacing the need for the customer to poll for changes. | 2026-09-06 |
