# Get Collection Indexes

Lists the index key patterns of a collection (read-only).

**Hub only.** Lists the MongoDB indexes of one collection, so you can check which fields are indexed before sorting or filtering on them. Read-only — indexes are created on the MongoDB side.

`GET /{version}/database/collections/{collectionName}/indexes`

The answer's `indexes` is a list of `{ name, keys: [{ field, order }] }` (`order` is `1` ascending or `-1` descending). A sort on a field is fast only when the field is the **first** key of an index.

Permission: `database:read` on the collection. AI tool: `get_collection_indexes`.

## In Cloud

The schema builder's **List** tab uses this list to mark slow sort columns — see [Schema Indexes](/codemash/cloud/database/collections/schema-indexes.md).

## Use it from code

TS `norbix.hub.database.getCollectionIndexes({ collectionName: 'orders' })` · Python `hub.database.get_collection_indexes("orders")` · Go `c.Hub.Database.GetCollectionIndexes(ctx, "orders", nil, &out)` · .NET `GetCollectionIndexesAsync(new GetCollectionIndexes { CollectionName = "orders" })` · CLI `norbix db indexes orders`.
