Usage

Choosing the environment

// Production (default) -> https://workflowy.com/api/v1/
var api = new WFExtendedAPI(apiKey);

// Beta -> https://beta.workflowy.com/api/v1/ (required by the mirror endpoints)
var beta = new WFExtendedAPI(apiKey, WFEnvironment.Beta);

// Custom host (proxy / staging). Must point at the '/api/v1/' root.
var custom = new WFExtendedAPI(apiKey, "https://my-proxy.example.com/api/v1/");

WFAPI exposes the same three constructors, plus a read-only BaseUrl property.

Mirrors

var beta = new WFExtendedAPI(apiKey, WFEnvironment.Beta);

// Create a mirror of nodeId under destinationId
var mirror = await beta.CreateMirrorAsync(nodeId, NodeIdentifier.Guid(destinationId));
Console.WriteLine($"{mirror.MirrorId} mirrors {mirror.OriginId}");

// Identify mirrors on any fetched node
var node = await beta.GetNodeAsync(mirror.MirrorId);
bool isMirror       = node.IsMirror;        // node.Data.Mirror.OriginId  is set
bool isMirrorOrigin = node.IsMirrorOrigin;  // node.Data.Mirror.MirrorIds is set

// Remove the mirror root - pass the MIRROR's id, the origin stays intact
await beta.DeleteMirrorAsync(mirror.MirrorId);

Note: deleting a node fails while that node (or any node in its subtree) is a mirror origin with live mirrors. Delete the mirror roots first.

Caching

ExportAllNodesCachedAsync keeps the last export in memory, per WFExtendedAPI instance:

var api = new WFExtendedAPI(apiKey);

// How long an export stays fresh (default: 5 minutes).
// TimeSpan.Zero disables the cache, leaving it as a fallback for HTTP 429 only.
api.CacheTtl = TimeSpan.FromMinutes(5);

// Served from the cache while it is younger than CacheTtl
var (nodes, fetchedAtUtc) = await api.ExportAllNodesCachedAsync();

// Bypass a still-fresh cache and hit the API
var fresh = await api.ExportAllNodesCachedAsync(forceRefresh: true);

// Drop the cached export
api.ClearCache();

FindNodeByHash(hash, enforce_new_cache: true) forwards to forceRefresh, so it always re-fetches.

On HTTP 429 (rate limited) the cached export is returned however stale it is - forceRefresh: true included - and the exception is only rethrown when there is nothing cached. So Dt is the timestamp of the data you actually got, not of the call.
