# Get Bulk Sync Schema

GET https://app.polytomic.com/api/bulk/syncs/{id}/schemas/{schema_id}

Returns the configuration of a single schema on a bulk sync.

Returns the sync mode, field selections, and any other configuration applied to
this schema on the bulk sync.

To modify the configuration, use
[`PATCH /api/bulk/syncs/{id}/schemas`](../../../../../../api-reference/bulk-sync/schemas/patch)
for a partial update across multiple schemas, or
[`PUT /api/bulk/syncs/{id}/schemas/{schema_id}`](../../../../../../api-reference/bulk-sync/schemas/update)
to fully replace this schema's configuration.

Reference: https://apidocs.polytomic.com/api-reference/bulk-sync/schemas/get

## Authentication

- `Authorization` header (bearer token, required) — Bearer user API key
- `Authorization` header (basic auth, required) — Basic organization-scoped API key

## Request

### Path parameters

- `id` (string, required) — Unique identifier of the bulk sync.
- `schema_id` (string, required) — Source-side schema identifier.

## Response

### 200

OK

- `data` (BulkSchema, optional)

## Errors

### 404 Not Found Error

Not Found

- `key` (string, optional)
- `message` (string, optional)
- `metadata` (map from string to any, optional)
- `status` (integer, optional)

## Types

### BulkSchema

- `data_cutoff_timestamp` (datetime, optional, nullable)
- `destination_history_output_name` (string, optional, nullable) — Name of the companion history table. Present only when history is enabled on a destination that supports it.
- `disable_data_cutoff` (boolean, optional)
- `enabled` (boolean, optional)
- `history_enabled` (boolean, optional, nullable) — Whether a companion history table is maintained beside this schema's output, recording every version observed on successive runs. Requires a replicate-mode sync to a destination reporting supports_history_mode. Always present in responses; when patching, omit it to keep the current value.
- `id` (string, optional)
- `output_name` (string, optional)
- `partition_key` (string, optional)
- `tracking_field` (string, optional)
- `user_output_name` (string, optional)
- `fields` (list of BulkField, optional, deprecated) — fields is not populated on the list endpoint and will be removed in a future version; retrieve individual schemas for fields.
- `filters` (list of BulkFilter, optional, deprecated) — filters is not populated on the list endpoint and will be removed in a future version; retrieve individual schemas for filters.

### BulkField

- `enabled` (boolean, optional)
- `id` (string, optional)
- `obfuscated` (boolean, optional)
- `output_name` (string, optional)
- `user_output_name` (string, optional)

### BulkFilter

- `function` (enum, required)
  - Allowed values: `Equality`, `Inequality`, `IsNull`, `IsNotNull`, `True`, `False`, `OnOrAfter`, `OnOrBefore`, `GreaterThan`, `GreaterThanEqual`, `LessThan`, `LessThanEqual`, `StringContains`, `StringStartsWith`, `StringEndsWith`, `StringDoesNotContain`, `StringDoesNotStartWith`, `StringDoesNotEndWith`, `StringOneOf`, `StringNotOneOf`, `Between`, `ArrayContains`, `ArrayDoesNotContain`, `InTheLast`, `RelativeOnOrBefore`, `RelativeOnOrAfter`, `StringLike`, `StringNotLike`, `StringMatchesTrimmed`
- `field_id` (string, optional) — Schema field ID to filter on.
- `value` (any, optional)
