Create a custom category
Creates a custom category. Requires the categories:write scope, writes_enabled, and an Idempotency-Key. Categories nest one level, so parent_id must name a visible top-level category. Reaching the per-account category limit returns 409 (waiting does not help), never a rate limit.

/v1/categories
Target server for requests. Edit to use your own host.
An opaque ff_ credential (ff_ak_ / ff_at_) presented as a Bearer token.
An opaque ff_ credential presented in the X-API-Key header.
The media type of the request body
A caller-chosen unique key (1-128 chars) that makes the write idempotent. A retry with the SAME key against the SAME operation, resource, and body replays the original response (Idempotency-Replayed: true). The same key with anything different — a changed body, a different endpoint, or a different {id} — is a 409 conflict; a still-in-flight duplicate is 409 with Retry-After. Required on every write. Stored for 24 hours. The key is bound to the target, not only to the payload, so reusing one key across two deletes (which carry no body at all) conflicts rather than replaying the first delete's response.
A Material icon name, or "emoji:" followed by a single emoji.
A hex color, e.g. "#FF5733".
