International SMS application

Overview

SMS applications carry out functions for the Huawei Cloud Message & SMS service. After you added an application, the system automatically allocates a unique application key and application secret and provides you with an application access address. The application key and application secret uniquely identify a user. They are carried for authentication and authorization during SMS API calling.

Notes

  • You can create an application only after your account is bound to a credit card. No application can be added if your Huawei Cloud account balance is insufficient. In this case, top up your account by following instructions provided in Topping Up an Account. If you have topped up your account and the application cannot be added, log out and log in to the system again.
  • International SMS applications are different from Chinese mainland SMS applications. You need to add each type of applications separately. A maximum of two international SMS applications can be added. To add more applications, submit a service ticket.
  • For details about the browsers supported by the Message & SMS console, see Which Browsers Are Supported?

Creating an Application

  1. Log in to the Message & SMS console.
  2. In the navigation pane, choose International SMS > Application Management.
  3. Click Add Application in the upper right corner. For details about how to create an application, see Table 1.
    Table 1 Adding an application

    Parameter

    Description

    Application Name

    The value can be customized. The value can contain a maximum of 64 characters, including letters, digits, and special characters (_.-@). The application name is used only for internal display and is irrelevant to the external API calls.

    SMS status reports Destination

    If the service party needs to receive status reports in batches, do not carry the callback field in the HTTP message delivery request, and configure a public network URL that can receive HTTP requests. The URL can be a domain name (recommended) or IP address:Port number. If this function is not required, you do not need to set this item.

    IP Whitelist

    Set this parameter based on the service requirements. You can configure up to 100 IP addresses for an application. Use commas (,) to separate IP addresses. It takes about 10 to 15 minutes for the IP whitelist to take effect. After the IP whitelist is successfully configured, the connection to the Message & SMS can be set up.

    AK/SK-based pushing authentication

    You can enable AK/SK authentication for receiving status reports, uplink SMS messages, or batch status reports. Enabling this function allows the platform to include an authentication field in the push messages it sends. The authentication of HTTP messages sent by the platform can be performed based on this field. For details, see AK/SK-based Pushing Authentication.

    To enable the push AK/SK authentication function, it is necessary to configure the pushing AK and pushing SK. It takes about 5 minutes for the configuration to take effect. If you want to enable AK/SK authentication after it is disabled, you need to reset the AK/SK.

    CAUTION:

    It takes 5 minutes for the new AK/SK to take effect. During this period, the status report or uplink SMS push authentication may fail. Exercise caution.

    Pushing AK

    The value is customizable and can contain only letters and digits.

    Pushing SK

    The value is customizable and must contain uppercase letters, lowercase letters, digits, and special characters (`~!@#$%^&*()-_=+\|[{}];:'",<.>/?) and spaces. The value cannot be the same as the account.
  4. Click OK.
