Invoke an Azure function

Set up the plugin to invoke an Azure function located in a custom domain.

Prerequisites

You have an Azure account with access to Azure Functions.
You have created a function.

Environment variables

AZURE_FUNCTION_NAME: The name of the Azure function to invoke.
AZURE_API_KEY: Your Azure API key.
AZURE_APP_NAME: The name of your Azure app.

Set up the plugin

Add this section to your declarative configuration file:

_format_version: "3.0"
plugins:
  - name: azure-functions
    config:
      functionname: ${{ env "DECK_AZURE_FUNCTION_NAME" }}
      appname: ${{ env "DECK_AZURE_APP_NAME" }}
      hostdomain: azurewebsites.net
      apikey: ${{ env "DECK_AZURE_API_KEY" }}

Make the following request:

curl -i -X POST http://localhost:8001/plugins/ \
    --header "Accept: application/json" \
    --header "Content-Type: application/json" \
    --data '
    {
      "name": "azure-functions",
      "config": {
        "functionname": "'$AZURE_FUNCTION_NAME'",
        "appname": "'$AZURE_APP_NAME'",
        "hostdomain": "azurewebsites.net",
        "apikey": "'$AZURE_API_KEY'"
      }
    }
    '

Make the following request:

curl -X POST https://{region}.api.konghq.com/v2/control-planes/{controlPlaneId}/core-entities/plugins/ \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --header "Authorization: Bearer $KONNECT_TOKEN" \
    --data '
    {
      "name": "azure-functions",
      "config": {
        "functionname": "'$AZURE_FUNCTION_NAME'",
        "appname": "'$AZURE_APP_NAME'",
        "hostdomain": "azurewebsites.net",
        "apikey": "'$AZURE_API_KEY'"
      }
    }
    '

Make sure to replace the following placeholders with your own values:

region: Geographic region where your Kong Konnect is hosted and operates.
controlPlaneId: The id of the control plane.
KONNECT_TOKEN: Your Personal Access Token (PAT) associated with your Konnect account.

See the Konnect API reference to learn about region-specific URLs and personal access tokens.
