Updating Edge Properties in Batches

Function

This API is used to update edge properties in batches.

URI

POST /ges/v1.0/{project_id}/graphs/{graph_name}/edges/properties/action?action_id={actionId}

**Table 1** URI parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID. For details about how to obtain the project ID, see Obtaining a Project ID.
graph_name	Yes	String	Graph name
actionId	Yes	String	Operator. Possible values: batch-update: Update the value of a property. batch-add: Add the value to a property. When the property's cardinality is single, the operation is the same as that of batch-update. When cardinality is list or set, the operator adds a value to a set. batch-del: Delete a property value.

Request Parameters

**Table 2** Request body parameters
Parameter	Mandatory	Type	Description
edges	Yes	Json	Edge array to be updated
ignoreError	No	Boolean	Whether to ignore the update error of specific edges. The default value is false, indicating that an error that causes the update failure must be detected. For example, if the edge to be updated does not exist, an error is reported and no edge is updated. If the value is true, similar errors are ignored and other edge properties without errors are updated.

**Table 3** edges parameter description
Parameter	Mandatory	Type	Description
source	Yes	String	Source vertex of an edge
target	Yes	String	Target vertex of an edge
index	No	String	Edge index. If this parameter is not set, the first edge between vertices is updated.
properties	Yes	Object	Value of each property

Response Parameters

**Table 4** Response body parameters
Parameter	Type	Description
errorMessage	String	System prompt. If execution succeeds, this parameter may be left blank. If execution fails, this parameter is used to display the error message.
errorCode	String	System prompt code. If execution succeeds, this parameter may be left blank. If execution fails, this parameter is used to display the error code.
result	String	Request result. If the request is successful, the value is success. If the request fails, the value is failed.

Example Request

Update edge properties in batches. The source vertex of the edge is 46, and the target vertices of the edge are 39 and 38.
