Update project

API Reference / Projects / Update project

Updates the specified project. Configurable properties include the project name, default compute settings, history retention period, and IP allowlist.

• project_id (string, path, required) The Neon project ID

• project (object, required)
  • settings (object, optional) Project-level settings, for example quota, allowed_ips, enable_logical_replication, and maintenance_window.

    • quota (object, optional) Per-project consumption quotas. If a quota is exceeded, all active computes are automatically suspended and cannot be started via API calls or incoming connections.

      The exception is logical_size_bytes, which is enforced per branch. If a branch exceeds its logical_size_bytes quota, computes can still be started, but write operations will fail—allowing data to be deleted to free up space. Computes on other branches are not affected.

      Setting logical_size_bytes overrides any lower value set by the neon.max_cluster_size Postgres setting.

      Quotas are enforced using per-project consumption metrics with the same names. These metrics reset at the start of each billing period. logical_size_bytes is also an exception—it reflects the total data stored in a branch and does not reset.

      A zero or empty quota value means “unlimited.”

      • active_time_seconds (integer, optional, format: int64) The total amount of wall-clock time allowed to be spent by the project's compute endpoints.

      • compute_time_seconds (integer, optional, format: int64) The total amount of CPU seconds allowed to be spent by the project's compute endpoints.

      • written_data_bytes (integer, optional, format: int64) Total amount of data written to all of a project's branches.

      • data_transfer_bytes (integer, optional, format: int64) Total amount of data transferred from all of a project's branches using the proxy.

      • logical_size_bytes (integer, optional, format: int64) Limit on the logical size of every project's branch.

        If a branch exceeds its logical_size_bytes quota, computes can still be started, but write operations will fail—allowing data to be deleted to free up space. Computes on other branches are not affected.

        Setting logical_size_bytes overrides any lower value set by the neon.max_cluster_size Postgres setting.

    • allowed_ips (object, optional) A list of IP addresses that are allowed to connect to the compute endpoint. If the list is empty or not set, all IP addresses are allowed. If protected_branches_only is true, the list will be applied only to protected branches.

      • ips (array, optional) A list of IP addresses that are allowed to connect to the endpoint.
      • protected_branches_only (boolean, optional) If true, the list will be applied only to protected branches.

    • enable_logical_replication (boolean, optional) Sets wal_level=logical for all compute endpoints in this project. All active endpoints will be suspended. Once enabled, logical replication cannot be disabled.

    • maintenance_window (object, optional) A maintenance window is a time period during which Neon may perform maintenance on the project's infrastructure. During this time, the project's compute endpoints may be unavailable and existing connections can be interrupted.

      • weekdays (array, required) A list of weekdays when the maintenance window is active. Encoded as ints, where 1 - Monday, and 7 - Sunday.

      • start_time (string, required) Start time of the maintenance window, in the format of "HH:MM". Uses UTC.

      • end_time (string, required) End time of the maintenance window, in the format of "HH:MM". Uses UTC.

    • block_public_connections (boolean, optional) When set, connections from the public internet are disallowed. This supersedes the AllowedIPs list. This parameter is under active development and its semantics may change in the future.

    • block_vpc_connections (boolean, optional) When set, connections using VPC endpoints are disallowed. This parameter is under active development and its semantics may change in the future.

    • audit_log_level (string, optional) Audit logging level, set only on HIPAA-enabled organizations (absent otherwise). Values: base, extended, full; HIPAA defaults to extended. Cannot be lowered back to base once extended or full. Possible values: base, extended, full

    • hipaa (boolean, optional) Enables HIPAA compliance mode for the project, including audit logging.

    • preload_libraries (object, optional) The shared libraries to preload into the project's compute instances.

      • use_defaults (boolean, optional) When true, the project's preload libraries include the platform default set in addition to any libraries listed in enabled_libraries.
      • enabled_libraries (array, optional) Names of shared preload libraries to enable for the project.
  • name (string, optional) The project name
  • default_endpoint_settings (object, optional) A collection of settings for a Neon endpoint

    • pg_settings (object, optional) A raw representation of Postgres settings

    • pgbouncer_settings (object, optional, deprecated) Deprecated. Use the endpoint-level connection pooler configuration instead. Removal scheduled for June 20, 2026.

    • autoscaling_limit_min_cu (number, optional) Minimum number of Compute Units for this endpoint. At least 0.25 and no greater than autoscaling_limit_max_cu.

    • autoscaling_limit_max_cu (number, optional) Default maximum number of Compute Units for endpoints created under this account. At least 0.25.

    • suspend_timeout_seconds (integer, optional, format: int64) Scale-to-zero idle timeout, in seconds, before the compute suspends. 0 uses the plan default; -1 disables scale-to-zero (never suspends). Minimum is plan-dependent (Scale: 60); maximum 604800 (one week). Free cannot change it; Launch can only enable or disable; Scale can set any value.

  • history_retention_seconds (integer, optional, format: int32) History window (point-in-time restore range) for all branches, in seconds. 0 disables it. Default 1 day (Free: 6 hours). Maximum depends on plan: Free 6 hours (21600), Launch 7 days (604800), Scale 30 days (2592000).

default General Error.

The request may or may not be safe to retry, depending on the HTTP method, response status code, and whether a response was received.

• If no response is returned from the API, a network error or timeout likely occurred.
• In some cases, the request may have reached the server and been successfully processed, but the response failed to reach the client. As a result, retrying non-idempotent requests can lead to unintended results.

The following HTTP methods are considered non-idempotent: POST, PATCH, DELETE, and PUT. Retrying these methods is generally not safe. The following methods are considered idempotent: GET, HEAD, and OPTIONS. Retrying these methods is safe in the event of a network error or timeout.

Any request that returns a 503 Service Unavailable response is always safe to retry.

Any request that returns a 423 Locked response is safe to retry. 423 Locked indicates that the resource is temporarily locked, for example, due to another operation in progress.

• request_id (string, optional) Unique identifier for the request, useful for debugging. You can set this value manually by including an X-Request-ID header in the request. If not provided, the value will be generated automatically.

• code (string, required) Machine-readable code classifying the error type. See message for a human-readable explanation. Default: ``

• message (string, required) Error message
