List canon supersession rows
Canon module
GET/canon/supersessionscanonSupersessions.list
A supersession edge. The graph stays acyclic. Returns a cursor page of canon supersession rows the caller may see. The default order is `domain`, then `code` ascending. Supports sparse fieldsets and the filter grammar.
- Requires the capability canon.taxonomy.read.
- OAuth scopes: canon.
- Cursor-paginated: limit, cursor, fields, sort and filter apply.
- Error statuses: 400, 401, 429. Errors are RFC 9457 problem details.
Path and query parameters
| Field | Type | Required | Description |
|---|---|---|---|
| limit | Limit | No | Page size. Default 50, maximum 200.Constraints: range 1 to 200 |
| cursor | Cursor | No | Opaque cursor from `next_cursor` of the previous page.Constraints: length 1 to any |
| fields | Fields | No | Sparse fieldset: a comma-separated list of top-level fields to return. `id` is always returned.Constraints: pattern ^[a-z_][a-z0-9_]*(,[a-z_][a-z0-9_]*)*$ |
| sort | Sort | No | Sort keys, comma-separated; a leading `-` sorts descending. Without `sort`, the documented default order applies (coded lists sort in numeric code order).Constraints: pattern ^-?[a-z_][a-z0-9_]*(,-?[a-z_][a-z0-9_]*)*$ |
| filter | Filter | No | Filter grammar `filter[field][op]=value`. Operators: eq, ne, lt, lte, gt, gte, in (comma-separated values), is_null (true or false) and contains. Conditions combine with AND. |
