# Call Method
# Generate Query Key
The project key should be generated first before using Open API. There are two types of project keys. The command used to generate project keys should be executed in ta-tool.
Log in to any TA server to execute the "su - ta" command to switch to ta user to execute ta-tool
Generate Root Key
ta-tool generate_root_secret
- This key would be applied to all projects
Generate Keys for a Single Project
ta-tool generate_api_secret -appid TEST-APPID
- The argument passed is the APPID of corresponding project. And the generated key could only be used for the corresponding project.
Note: When the same project or root key has been executed repeatedly, a new key would be generated, while the previous key would become invalid.
# API Call Rules
The API submits the call request using the HTTP GET or POST method, and the URL of the call is:
http://$HOST:8992/$API_PATH?token=$API_SECRET
$HOST refers to Server address, and its value is usually ta2. $API_PATH refers to a specific API route, e.g., open/event-analyze. $API_SECRET is the key.
The API submits the call request using the HTTP GET or POST method. The POST request message body is in JSON format. For detailed parameters configuration, please check relevant documents.
The response message body is in JSON format, and the basic structure is as follows.
{
"return_code": 0,
"return_message": "success",
"data": {...},
"stackMessage": "",
"showStackMessage": false
}
