Step 3: Configuring the Environment

1. Download and install Postman.

   Postman 7.24.0 is recommended.

2. Download the Postman configuration file for Content Moderation.
3. Import the configuration file.
   1. Open and log in to Postman.
   2. Choose File > Import in the upper left corner. In the displayed dialog, click Upload Files to import the configuration file.

4. After the configuration file is imported, it is displayed in the Collections directory in the left navigation pane.
   Figure 3 Configuration Files
   

Step 4: Using a Token for Authentication

A token is a user's access credential, which includes user identities and permissions. When you call an API to access a cloud service, a token is required for identity authentication.

1. In the Collections directory in the navigation pane of Postman, click the get-token configuration file.
2. Click Body. Enter the username, password, and domain name.
   

   To obtain the username, password, and domain name, perform the following steps:

   1. Log in to the management console.
   2. Hover the cursor on the username and choose My Credentials from the drop-down list. Copy the IAM username and account name to username and domainname, and enter the IAM user password.

3. Click Send to send a request, and obtain and copy the token.

   In Headers, obtain the value of X-Subject-Token, which is the token. The token is valid for 24 hours.

   Figure 5 Obtaining a token
   

Step 5: Calling a Service API

1. In the Collections directory in the navigation pane of Postman, click the Moderation_image configuration file.
2. Click Headers and copy the token value to X-Auth-Token.
   Figure 6 Entering the token
   
3. Click Body and enter the text to be checked for the text parameter.
   • For details about other parameters in the body, see the Text Moderation API.
     Figure 7 Modifying the parameters
     
4. Click Send to send the request and obtain the API call results.

   {
       "result": {
           "detail": {},
           "suggestion": "pass"
       }
   }

(Optional) Step 6: Viewing the Number of API Calls

1. View the number of API calls. Choose Service List > Text Moderation, and view call statistics and call details. See Figure 8.
   Figure 8 Call statistics
   
   • The Call Statistics section provides three statistical charts, displaying daily calls, daily blocked text, and daily reviewed text. You can set a time range to view the change of the number of API calls within the time range.
   • The Call Details section lists the total number of calls, blocks, reviews, and passes every day. This helps you better understand service calls and their statuses.
     

     • block indicates that sensitive information is contained and the information is blocked.

     • pass indicates that sensitive information is not contained and the information is approved.

     • review indicates that manual review is required.

2. View monitoring metrics. You can click View Metric to view historical data such as successful and failed calls on the Cloud Eye console. See Figure 9.
