--- title: "POST /v1/projects/{projectId}:commit" method: POST path: "/v1/projects/{projectId}:commit" tags: ["projects"] --- # POST /v1/projects/{projectId}:commit `POST /v1/projects/{projectId}:commit` Commits a transaction, optionally creating, deleting or modifying some entities. ## Path parameters - `projectId` string, required ## Request body - CommitRequest — The request for Datastore.Commit. - `mutations` Mutation[] — The mutations to perform. When mode is `TRANSACTIONAL`, mutations affecting a single entity are applied in order. The following sequences of mutations affecting a single entity are not permitted in a single `Commit` request: - `insert` followed by `insert` - `update` followed by `insert` - `upsert` followed by `insert` - `delete` followed by `update` When mode is `NON_TRANSACTIONAL`, no two mutations may affect a single entity. - `update` Entity — A Datastore data object. Must not exceed 1 MiB - 4 bytes. - `properties` object — The entity's properties. The map's keys are property names. A property name matching regex `__.*__` is reserved. A reserved property name is forbidden in certain documented contexts. The map keys, represented as UTF-8, must not exceed 1,500 bytes and cannot be empty. - `key` Key — A unique identifier for an entity. If a key's partition ID or any of its path kinds or names are reserved/read-only, the key is reserved/read-only. A reserved/read-only key is forbidden in certain documented contexts. - `partitionId` PartitionId — A partition ID identifies a grouping of entities. The grouping is always by project and namespace, however the namespace ID may be empty. A partition ID contains several dimensions: project ID and namespace ID. Partition dimensions: - May be `""`. - Must be valid UTF-8 bytes. - Must have values that match regex `[A-Za-z\d\.\-_]{1,100}` If the value of any dimension matches regex `__.*__`, the partition is reserved/read-only. A reserved/read-only partition ID is forbidden in certain documented contexts. Foreign partition IDs (in which the project ID does not match the context project ID ) are discouraged. Reads and writes of foreign partition IDs may fail if the project is not in an active state. - `projectId` string — The ID of the project to which the entities belong. - `databaseId` string — If not empty, the ID of the database to which the entities belong. - `namespaceId` string — If not empty, the ID of the namespace to which the entities belong. - `path` PathElement[] — The entity path. An entity path consists of one or more elements composed of a kind and a string or numerical identifier, which identify entities. The first element identifies a _root entity_, the second element identifies a _child_ of the root entity, the third element identifies a child of the second entity, and so forth. The entities identified by all prefixes of the path are called the element's _ancestors_. An entity path is always fully complete: *all* of the entity's ancestors are required to be in the path along with the entity identifier itself. The only exception is that in some documented cases, the identifier in the last path element (for the entity) itself may be omitted. For example, the last path element of the key of `Mutation.insert` may have no identifier. A path can never be empty, and a path can have at most 100 elements. - `name` string — The name of the entity. A name matching regex `__.*__` is reserved/read-only. A name must not be more than 1500 bytes when UTF-8 encoded. Cannot be `""`. Must be valid UTF-8 bytes. Legacy values that are not valid UTF-8 are encoded as `__bytes__` where `` is the base-64 encoding of the bytes. - `kind` string — The kind of the entity. A kind matching regex `__.*__` is reserved/read-only. A kind must not contain more than 1500 bytes when UTF-8 encoded. Cannot be `""`. Must be valid UTF-8 bytes. Legacy values that are not valid UTF-8 are encoded as `__bytes__` where `` is the base-64 encoding of the bytes. - `id` string, int64 — The auto-allocated ID of the entity. Never equal to zero. Values less than zero are discouraged and may not be supported in the future. - `conflictResolutionStrategy` 'STRATEGY_UNSPECIFIED' | 'SERVER_VALUE' | 'FAIL' — The strategy to use when a conflict is detected. Defaults to `SERVER_VALUE`. If this is set, then `conflict_detection_strategy` must also be set. - `propertyTransforms` PropertyTransform[] — Optional. The transforms to perform on the entity. This field can be set only when the operation is `insert`, `update`, or `upsert`. If present, the transforms are be applied to the entity regardless of the property mask, in order, after the operation. - `property` string — Optional. The name of the property. Property paths (a list of property names separated by dots (`.`)) may be used to refer to properties inside entity values. For example `foo.bar` means the property `bar` inside the entity property `foo`. If a property name contains a dot `.` or a backlslash `\`, then that name must be escaped. - `removeAllFromArray` ArrayValue — An array value. - `values` Value[] — Values in the array. The order of values in an array is preserved as long as all values have identical settings for 'exclude_from_indexes'. - `booleanValue` boolean — A boolean value. - `arrayValue` ArrayValue — recursive - `meaning` integer — The `meaning` field should only be populated for backwards compatibility. - `keyValue` Key — A unique identifier for an entity. If a key's partition ID or any of its path kinds or names are reserved/read-only, the key is reserved/read-only. A reserved/read-only key is forbidden in certain documented contexts. - `partitionId` PartitionId — A partition ID identifies a grouping of entities. The grouping is always by project and namespace, however the namespace ID may be empty. A partition ID contains several dimensions: project ID and namespace ID. Partition dimensions: - May be `""`. - Must be valid UTF-8 bytes. - Must have values that match regex `[A-Za-z\d\.\-_]{1,100}` If the value of any dimension matches regex `__.*__`, the partition is reserved/read-only. A reserved/read-only partition ID is forbidden in certain documented contexts. Foreign partition IDs (in which the project ID does not match the context project ID ) are discouraged.

If a key's partition ID or any of its path kinds or names are reserved/read-only, the key is reserved/read-only. A reserved/read-only key is forbidden in certain documented contexts. - `partitionId` PartitionId — A partition ID identifies a grouping of entities. The grouping is always by project and namespace, however the namespace ID may be empty. A partition ID contains several dimensions: project ID and namespace ID. Partition dimensions: - May be `""`. - Must be valid UTF-8 bytes. - Must have values that match regex `[A-Za-z\d\.\-_]{1,100}` If the value of any dimension matches regex `__.*__`, the partition is reserved/read-only.

The entities identified by all prefixes of the path are called the element's _ancestors_. An entity path is always fully complete: *all* of the entity's ancestors are required to be in the path along with the entity identifier itself. The only exception is that in some documented cases, the identifier in the last path element (for the entity) itself may be omitted. For example, the last path element of the key of `Mutation.insert` may have no identifier.

If a property name contains a dot `.` or a backslash `\`, then that name must be escaped. A path must not be empty, and may not reference a value inside an array value. - `delete` Key — A unique identifier for an entity.
