This document describes how to quickly create an event-triggered function in the console.
Compared with event-triggered functions, the HTTP-triggered functions provided by SCF focus more on optimizing web services. Click here to understand and quickly create an HTTP-triggered function.

Step 1. Sign up for a Tencent Cloud Account

If you already have a Tencent Cloud account, ignore this step.

Step 2. Topping Up Online

SCF users are entitled to a certain free tier of resource usage and invocations each month as shown below. There is no free tier for public network outbound traffic. SCF is billed by the actual Tencent Cloud resource usage. If you need to use other postpaid Tencent Cloud resources, top up your account first as instructed in Payment Methods before making purchases.

Step 3. Authorizing TKE

Log in to the Tencent Cloud console, select Products > Serverless Cloud Function to enter the SCF console, and follow the prompts to authorize SCF. (If you have already authorized SCF, skip this step.)

Step 4. Create a function

1. Click Function Service on the left sidebar to enter the Function Service page.
2. Select Guangzhou at the top of the page and click Create as shown below:
   
3. Enter the basic information of the function on the Create Function page and click Next as shown below:
   
   • Create Method: select Function Template.
   • Filter: after entering helloworld, press "Enter" to search for and select the helloworld template. SCF supports multiple runtime environments. This function uses Python 2.7 as an example.
4. The function name is automatically generated by default and can be modified as needed. Keep the default function configuration and click Complete as shown below:
   
   After the function is created, you will be automatically redirected to the "Function Configuration" page where you can view the configuration information.
5. Select the Function code tab to view or edit the function code online as shown below:
   

Step 5. Deploy the function (including trigger configuration)

1. After editing the function code online, click Deploy, and the function will be deployed.
2. On the details page of the created function, select Trigger Management on the left and click Create a Trigger.
3. In the Create a Trigger window that pops up, set Trigger Method to API Gateway Trigger, unselect Enable integration response, and keep other parameters as default as shown below:
   
4. Click Submit to complete the function deployment and trigger configuration.

Step 6. Test in the cloud

{
"key1": "test value 1",
"key2": "test value 2"
}

Step 7. View logs and monitoring data

Step 8. Delete the function

After the function starts running, it consumes resources. In order to avoid unnecessary fees, this step shows you how to clear all resources.

1. Select Function Service on the left sidebar and click Delete on the right of the function to be deleted as shown below:
   
2. Confirm the information in the Delete Function pop-up window and click OK.
