Updating a bulk sync is a **full replacement** of the sync's top-level configuration. Every field in the request body is written to the sync; any field you omit is cleared or reset to its default value. To make a partial change — for example, toggling `active` or swapping a schedule — fetch the current sync with [`GET /api/bulk/syncs/{id}`](../../../../api-reference/bulk-sync/get), modify the fields you want to change, and send the complete object back in the update request. Updates to `active`, `schedules`, and `policies` take effect immediately. Changes to source or destination configuration take effect on the sync's next execution. Because omitted fields are reset to their defaults, the discovery and naming options behave the same as on create when left out: * `automatically_add_new_objects` resets to not enabling newly discovered source objects automatically. * `automatically_add_new_fields` resets to enabling newly discovered fields on already selected objects. * `normalize_names` resets to enabled. Send the existing values explicitly if you want to preserve a non-default or non-empty setting. > 📘 Updating schemas > > When `schemas` is present, it replaces the sync's schema selection: schemas > not in the list are disabled. When `schemas` is omitted or empty, the sync's > schemas are left unchanged. Use the > [Update Bulk Sync Schemas](../../../../api-reference/bulk-sync/schemas/patch) > endpoint to change a subset of schemas, or > [Update Bulk Sync Schema](../../../../api-reference/bulk-sync/schemas/update) > to replace a single schema's configuration. Reference: https://apidocs.polytomic.com/api-reference/bulk-sync/update ## 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 to update ### Body (application/json) This endpoint expects an UpdateBulkSyncRequest. - `default_schedule` (BulkSyncDefaultScheduleRequest, required) — The default bulk sync schedule. This schedule applies to all fields and schemas. Schedules are interpreted in UTC. - `destination_configuration` (map from string to any, required) — Destination-specific bulk sync configuration (e.g. output schema name, file format). The accepted keys depend on the destination connection type. - `destination_connection_id` (string, required) — Unique identifier of the connection rows are written to - `mode` (enum, required) — How source data is written to the destination. replicate keeps the destination in sync with the source; snapshot writes a timestamped copy per execution; append adds every delivered record, including full reads, without updating existing rows. - Allowed values: `snapshot`, `replicate`, `append` - `name` (string, required) — Human-readable name for the bulk sync - `source_connection_id` (string, required) — Unique identifier of the connection rows are read from - `active` (boolean, optional, nullable) — Whether the sync is active. Inactive syncs do not run on their schedule but can still be triggered manually. - `additional_schedules` (list of BulkSyncAdditionalScheduleRequest, optional, nullable) — Additional bulk sync schedules. Schedule times are interpreted in UTC. - `automatically_add_new_fields` (enum, optional) — Controls whether Polytomic automatically enables newly discovered fields on existing objects. Valid values depend on the source backend. - Allowed values: `all`, `onlyIncremental`, `onlyNonIncremental`, `none` - `automatically_add_new_objects` (enum, optional) — Controls whether Polytomic automatically enables newly discovered source objects (tables). Valid values depend on the source backend. - Allowed values: `all`, `onlyIncremental`, `onlyNonIncremental`, `none` - `concurrency_limit` (integer, optional, nullable) — Override the default concurrency limit for this sync. - `data_cutoff_timestamp` (datetime, optional, nullable) — Global cutoff applied across schemas. Source records older than this timestamp are excluded from sync runs. - `disable_record_timestamps` (boolean, optional, nullable, default: false) — When true, Polytomic will not add its own timestamp columns to destination rows. - `normalize_names` (enum, optional) — Controls whether destination object and field names are normalized (e.g. lowercased, special characters replaced). Valid values depend on the destination backend. - Allowed values: `enabled`, `disabled`, `legacy` - `organization_id` (string, optional, nullable) — Organization the sync belongs to. Only used by partner callers; normal callers are always scoped to their own organization. - `policies` (list of string, optional, nullable) — Identifiers of permissions policies applied to the bulk sync - `resync_concurrency_limit` (integer, optional, nullable) — Override the default resync concurrency limit for this sync. - `schemas` (list of UpdateBulkSyncRequestSchemasItems, optional, nullable) — Schemas to sync. Schemas not in the list are disabled; if omitted or empty, the sync's schemas are left unchanged. - `source_configuration` (map from string to any, optional, nullable) — Source-specific bulk sync configuration (e.g. replication slot name, sync lookback). The accepted keys depend on the source connection type. ## Response ### 200 OK - `data` (BulkSyncResponse, optional) — The bulk sync ## Errors ### 400 Bad Request Error Bad Request - `key` (string, optional) — Machine-readable error key, when the error has one - `message` (string, optional) — Error message - `metadata` (map from string to any, optional) — Structured details about the error, when available - `status` (integer, optional) — HTTP status code ### 403 Forbidden Error Forbidden - `key` (string, optional) — Machine-readable error key, when the error has one - `message` (string, optional) — Error message - `metadata` (map from string to any, optional) — Structured details about the error, when available - `status` (integer, optional) — HTTP status code ### 404 Not Found Error Not Found - `key` (string, optional) — Machine-readable error key, when the error has one - `message` (string, optional) — Error message - `metadata` (map from string to any, optional) — Structured details about the error, when available - `status` (integer, optional) — HTTP status code ### 409 Conflict Error Conflict - `key` (string, optional) — Machine-readable error key, when the error has one - `message` (string, optional) — Error message - `metadata` (map from string to any, optional) — Structured details about the error, when available - `status` (integer, optional) — HTTP status code ### 500 Internal Server Error Internal Server Error - `key` (string, optional) — Machine-readable error key, when the error has one - `message` (string, optional) — Error message - `metadata` (map from string to any, optional) — Structured details about the error, when available - `status` (integer, optional) — HTTP status code ## Types ### BulkSyncDefaultScheduleRequest - `frequency` (enum, required) — How often the sync runs on this schedule.
