ECL2.0 provides API depending on Customers’ purposes, and they can control almost al the functions via API.
API enables Customers to control resources, and utilize management functions such as checking billing status via API.
These kind of operations can be performed via control panel of GUI, but API allows Customers to further automate their operations.
For detailed information about the API, please check the API Reference <https://ecl.ntt.com/documents/api-references/>

API Configuration

Both “API key” and “API secret key” are required for API usage. Both of them are assigned per user.
Additionally, Customers can control their API requests via the Internet by accessing to API endpoint.




This is the ID necessary for authentication to enable API access. Authentication by API key enables Customers to access to each resource via API endpoint, and send API requests.
Unique value per user is assigned and Customers can regenerate it as needed.

API Secret Key

This is the secret key necessary for authentication to enable API access. API secret key is needed in conbination with API key.
Unique value per user is assigned and Customers can regenerate it as needed.

API Endpoint

This is the defined URL for API access.
You can control various resources by accessing this URL.The end point of API depends on each region and service menu.

Menus providing API

The menu that is provided by the API is API Reference <https://ecl.ntt.com/documents/api-references/>

Terms and Conditions of Use

Service Provider limits the number of API request to ensure the health condition of our infrastructure and Customers’ environment.

  • “200 requests/second/source IP address” or “1,000 requests/minute/user”

Once the number of API request from Customers exceeds the limit, the safeguard runs on against their API requests and restrict them temporally.

1.1.7. API permission management API permission management is provided in ECL2.0

In ECL2.0, the ability to control the execution authority of various API is provided.
Customers can control the API execution permission of the user by using this function with a variety of conditions.
Example of conditions:
· Only specific APIs are executable (Limited to Read Only, etc.)
· Only executable for a particular resource
· A particular transmission can be run, etc only from the original global IP address.


The GUI provided in the ECL2.0, internally, has been achieved by executing the API to the appropriate operation of the on-screen in the operation.Therefore, By using this API permission management function, customers can also execute permission on the GUI to limit in the same way.

By 3 elements, such as the following, User, IAM (Identity and Access Management) Group, IAM Role, the authority is controlled.




individual users belonging to the agreement of the ECL2.0 (administrative user, or, general users)

IAM role

The use terms of API and the conditions to run API are defined in the white list format.
1 IAM role can have multiple authorization API.

IAM Group

Grouping the IAM roles
Serve to characterize the string of the user and the IAM role.

As shown in the following figure, a user can belong to multiple IAM groups, the IAM Group is defined by 1 or multiple IAM roles.

User/Group/Role Authority definition of IAM role

IAM roles are defined primarily by the following factors.
Information other than the following is held at each API also can be specified as any element, customers can also specify a wild card by specifying the asterisk (*) as the value.

The GUI provides examples of typical role settings as templates, so you can select and configure this template.




Access the original global IP address that is allowed to use


API name that is permitted to use


API resource name that is permitted to use


Method name that is permitted to use

The following is a setting example of a role if you want to set permissions for read-only (Read Only).

IAM_Role #1 Default IAM group, default IAM role

At the moment of creation of the ECL2.0 contract, the default IAM group and the default IAM role will be created by the system, and soon after that all the users created will be tied to the default IAM group.
In the default IAM roles, the execute permission to all the API are defined. Since it’s tied to a default IAM group, execution permission of all the executable API to the Initially all users in that user type.

The default of the IAM group and the default of the IAM role, can not be deleted.
In addition, the administrative user, can not be deviated from the default IAM group. Judgment of authority

If one user is tied to more than 1 authority setting, based on the following determination method, the authority decision is done.


The setting of API permission management is evaluated together with authority by user type (admin user or general user) and authority by tenant access permission.For example, general users can not create tenants.In addition, operations on resources belonging to tenants who do not have tenant access permission can also be set but can not be executed.Please refer to “User management” for user type and “Tenant management” for tenant access permission.

1.If a IAM role is composed by multiple authority definitions → A or B


In the following example, a user that is tied to this group, will be set as “Creating a virtual server (POST), or, edit (PUT) is possible”.


2.User belongs to 1 of the IAM group, if IAM group is defined in more than 1 IAM role → A and B


In the following example, the authority specified can be run in the IAM Role #2-1, but by IAM Role # 2-2, customers can set the AND conditions like [the case of a tenant ID is” 123456789 “].


3.If a user belongs to more than 1 IAM group, IAM group is defined by a multiple IAM roles → A or B


In the following example, on that granted read-only privileges for the entire contract at the IAM Group # 1, it will be configured to allow the creation and editing virtual of the servers belonging to the tenant ID 1234567890 by Group # 2.

pattern_3_config Terms and Conditions of Use

-This function can be set only by administrative users, general user can not set it.

1.1.8. Approval Function Function Overview

The approval function is a function that can issue approval requests and answer approval / rejection of requests.
In the approval function, approval requests for tenants, contracts and users are issued.
For example, in ECL 2.0, all resources are usually placed in the tenant, and the scope of the impact of the operation is limited to the tenant, but if the user tries to perform an operation that exceeds the tenant and affects the resources of other tenants It is necessary to obtain approval from the user of the counter tenant.
In this case, the executor of the operation issues a request, which can be realized when the user of the opposing tenant approves it.The approval function can be used beyond the contract.

As an application scene of the approval function, there is an Enterprise Cloud 2.0 Connection that connects tenants.
This is to provide network connectivity beyond tenants by connecting the firewall of the connection source tenant and the logical network of the counter tenant.
For the Enterprise Cloud 2.0 connection, please see here Enterprise Cloud 2.0 connection Approval request parameters

Approval requests include the following parameters.
The parameters that can be specified by the user depend on the menu of the side issuing the approval request.
