Click Create Trigger and select API Gateway (Dedicated) for Trigger Type. API Instance: Select a gateway. If no gateway is available, click Create API Instance. API Name: Retain the default name. API Group: If no API group is available, click Create API Group to create one.
Gateway Response: Select default. Authentication Mode: Select Custom. Custom Authorizer: Select Authorizer_test. Figure 1 Configuring frontend definition Figure 2 Configuring security settings For more parameters, see Creating an API.
Table 2 Event template description Template Name Description API Gateway (Dedicated Gateway) Simulates a dedicated APIG event to trigger your function. Cloud Trace Service (CTS) Simulates a CTS event to trigger your function.
Click Create Trigger and select API Gateway (Dedicated) for Trigger Type. API Instance: Select a gateway. If no gateway is available, click Create API Instance. API Name: Retain the default name. API Group: If no API group is available, click Create API Group to create one.
API Gateway FunctionGraph functions are invoked over HTTPS by defining REST APIs with specified backend services. For details, see the APIG User Guide. OBS FunctionGraph functions are created to process OBS bucket events, such as object creation or deletion events.
