URI

POST /v2/{project_id}/graphs

**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.

Request Parameters

**Table 2** Request header parameter
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	User token. It is used to obtain the permission to call APIs. For details about how to obtain the token, see Authentication. The value of X-Subject-Token in the response header is the token.

**Table 3** Request body parameter
Parameter	Mandatory	Type	Description
graph	Yes	graph object	Graph type

**Table 4** graph
Parameter	Mandatory	Type	Description
name	Yes	String	A graph name must start with a letter and contains 4 to 50 characters consisting of letters, digits, hyphens (-), and underscores (_). It cannot contain special characters.
graph_size_type_index	Yes	String	Graph size type index: 0: Ten-thousand-edge 1: Million-edge 2: Ten-million-edge 3: Hundred-million-edge 4: Billion-edge 5: Ten-billion-edge 6: database edition 401: Billion-edge-pro
arch	No	String	Graph instance's CPU architecture type. The value can be x86_64 or aarch64. The default value is x86_64. x86_64: x86 64-bit architecture aarch64: Arm 64-bit architecture
vpc_id	Yes	String	VPC ID
subnet_id	Yes	String	Subnet ID in the VPC
security_group_id	Yes	String	Security group ID
public_ip	No	public_ip object	Public IP address. If the parameter is not specified, public connection is not used by default.
enable_multi_az	No	Boolean	Whether the created graph supports the cross-AZ mode. The default value is false. If the value is true, the system will create the ECSs in the graph in two AZs. If this parameter is not specified when you create a graph, all ECSs in the graph are created in one AZ.
encryption	No	encryption object	Whether to encrypt the graph instance. The graph instance is not encrypted by default.
lts_operation_trace	No	lts_operation_trace object	Whether to enable audit logs. This function is disabled by default.
sys_tags	No	Array of sys_tags objects	Enterprise project information. If this parameter is not specified, this function is disabled (default).
tags	No	Array of tags objects	TMS tags for expenses. This function is disabled by default.
enable_rbac	No	Boolean	Whether to enable granular permission control for the created graph. The default value is false, indicating that granular permission control is disabled. If this parameter is set to true, no user has the permission to access the graph. To access the graph, you need to call the granular permission control API of the service plane to set the required permissions.
enable_full_text_index	No	Boolean	Whether to enable full-text index control for the created graph. The default value is false, indicating that full-text index control is disabled. If this parameter is set to true, full-text indexes are available for Billion-edge-pro graphs, and a Cloud Search Service (CSS) cluster will be created when you create a graph. NOTE: If you enable full-text indexes: If the CSS has been deployed, the system automatically creates a CSS cluster during the creation of the graph instance, which will take a long time. If the CSS is not deployed, the graph creation will fail.
enable_hyg	No	Boolean	Whether to enable HyG for the graph. This parameter is available for database edition graphs only.
crypt_algorithm	Yes	String	Graph instance cryptography algorithm. Available values are as follows: generalCipher: Chinese cryptographic algorithm SMcompatible: Commercial cryptography algorithm (compatible with international ones)
enable_https	Yes	Boolean	Whether to enable the security mode. This mode may damage GES performance greatly.
product_type	No	String	Graph type. The value can be InMemory (default value) or Persistence. If graph_size_type_index is 6, the value must be Persistence. InMemory: memory edition Persistence: database version
vertex_id_type	No	vertex_id_type object	ID type of vertices. This parameter is mandatory only for database edition graphs. NOTE: The vertex ID type cannot be changed once set. Exercise caution when setting this parameter.
enable_multi_label	No	Boolean	Whether multi-lableing is enabled.
capacity_ratio	No	Integer	Capacity rate of a graph. This parameter is only available for Ten-billion-edge graphs of the database edition since version 2.3.18.
is_dynamic_graph	No	Boolean	Whether a graph is a dynamic one

**Table 5** public_ip
Parameter	Mandatory	Type	Description
public_bind_type	No	String	Binding type of an EIP. The value can be either of the following: auto_assign bind_existing
eip_id	No	String	ID of an EIP. When publicBindType is set to bind_existing, its value is the ID of an EIP that has been created but has not been bound. When publicBindType is set to auto_assign, its value is set to null.

**Table 6** encryption
Parameter	Mandatory	Type	Description
enable	No	Boolean	Whether to enable data encryption The value can be true or false. The default value is false.
master_key_id	No	String	ID of the customer master key created by DEW in the project corresponding to the graph creation

**Table 7** lts_operation_trace
Parameter	Mandatory	Type	Description
enable_audit	No	Boolean	Whether to enable graph audit. The default value is false.
audit_log_group_name	No	String	LTS log group name

**Table 8** sys_tags
Parameter	Mandatory	Type	Description
key	No	String	Key of the enterprise project. The value is _sys_enterprise_project_id.
value	No	String	Enterprise project ID. You can obtain it from the enterprise project.

**Table 9** tags
Parameter	Mandatory	Type	Description
key	No	String	Tag key
value	No	String	Tag value

**Table 10** vertex_id_type
Parameter	Mandatory	Type	Description
id_type	Yes	String	Vertex ID type. The value can be fixedLengthString or hash. fixedLengthString: Vertex IDs are used for internal storage and compute. Specify the length limit. If the IDs are too long, the query performance can be reduced. Specify the length limit based on your dataset vertex IDs. hash: Vertex IDs are converted into hash code for storage and compute. There is no limit on the ID length. However, there is an extremely low probability, approximately 10^(-43), that the vertex IDs will conflict. If you cannot determine the maximum length of a vertex ID, set this parameter to Hash.
id_length	No	Integer	This parameter is mandatory if id_type is fixedLengthString. The value ranges from 1 to 128.
