Deleting Edges in Batches

Function

This API is used to delete edges in batches based on the source vertices, target vertices, and indexes of the edges.

Example Request

Delete edges in batches. The source vertices of the edges are 39631050_Landscape and 27803870_Landmark building, and the target vertices of the edges are 27803870_Landmark building and 27661363_Villa hot spring.

Request Parameters

**Table 2** Request body parameters
Parameter	Mandatory	Type	Description
edges	Yes	Object	Edge array to be deleted
executionMode	No	String	sync indicates the synchronous mode, and async indicates the asynchronous mode. The default value is sync.
ignoreError	No	Boolean	Whether to ignore errors, for example, the edge to delete does not exist. The default value is false, indicating that errors will not be ignored. Errors in JSON format cannot be ignored.

**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
label	No	String	Label of an edge. If the index parameter is set, this parameter is ignored. If the index parameter is not set, an edge that meets the source, target, and label conditions is deleted. If the specified label value does not exist in the schema or the edge with the same label does not exist, no edge will be deleted.

Response Parameters

**Table 5** Response body parameters
Parameter	Mandatory	Type	Description
errorMessage	No	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	No	String	System prompt. If execution succeeds, this parameter may be left blank. If execution fails, this parameter is used to display the error code.
