How can I create 1 or more workflows in an existing Azure Logic App (Standard) using an ARM template in combination with Terraform?

Question

When I try to create a workflow in my already existing Logic App (Standard). I use 1 file (main.tf) for deployment, I know it's not best practice but it is for testing purposes.

This is my main.tf:

resource "azurerm_resource_group" "tftest" {
name     = "Terraform-resourcegroup-klant1"
location = "West Europe"
}

data "azurerm_resource_group" "serviceBusRG" {
name = "Service_bus_integration"
}

data "azurerm_servicebus_namespace" "customerServiceBus" {
name = "CustomerIntegrationASB"
resource_group_name = data.azurerm_resource_group.serviceBusRG.name
}

data "azurerm_managed_api" "apitf" {
name     = "servicebus"
location = azurerm_resource_group.tftest.location
}

resource "azurerm_api_connection" "apiConncection" {
name                = "Servicebus-connection"
resource_group_name = azurerm_resource_group.tftest.name
managed_api_id      = data.azurerm_managed_api.apitf.id
display_name        = "API connection 1 test"

parameter_values = {
connectionString = data.azurerm_servicebus_namespace.customerServiceBus.default_primary_connection_string
}
}

resource "azurerm_servicebus_topic" "tenableTopic" {
name = "TenableTerraform"
namespace_id = data.azurerm_servicebus_namespace.customerServiceBus.id
max_size_in_megabytes = 1024
}

resource "azurerm_servicebus_subscription" "tenableSub" {
name = "Klant1"
topic_id = azurerm_servicebus_topic.tenableTopic.id
max_delivery_count = 1
}

resource "azurerm_servicebus_subscription_rule" "tenableFilter" {
name = "Klant1filter"
subscription_id = azurerm_servicebus_subscription.tenableSub.id
filter_type = "CorrelationFilter"

    correlation_filter {
    label = "Klant 1-naam"

}
}

resource "azurerm_storage_account" "storageAccountKlant1" {
name = "klant1storageaccount"
resource_group_name = azurerm_resource_group.tftest.name
location = azurerm_resource_group.tftest.location
account_tier = "Standard"
account_replication_type = "LRS"

}

resource "azurerm_service_plan" "appServicePlanKlant1" {
name = "AppServicePlanKlant1"
location = azurerm_resource_group.tftest.location
resource_group_name = azurerm_resource_group.tftest.name
os_type = "Windows"
sku_name = "WS1"
}

resource "azurerm_logic_app_standard" "logicAppKlant1" {
name = "LogicAppKlant1"
location = azurerm_resource_group.tftest.location
resource_group_name = azurerm_resource_group.tftest.name
app_service_plan_id = azurerm_service_plan.appServicePlanKlant1.id
storage_account_name = azurerm_storage_account.storageAccountKlant1.name
storage_account_access_key = azurerm_storage_account.storageAccountKlant1.primary_access_key

    app_settings = {
      "FUNCTIONS_WORKER_RUNTIME_VERSION" = "~4"
    }

}

resource "azurerm_resource_group_template_deployment" "workflowtje" {
name = "TemplateWorkflowKlant1"
resource_group_name = azurerm_resource_group.tftest.name
deployment_mode = "Complete"

template_content = file("/home/customer/vscode/terraform/logicappcomplete/jsons/readvulns.json")

parameters_content = jsonencode({
"logicAppName" = {
value = azurerm_logic_app_standard.logicAppKlant1.name
}
})
}

This .tf file contains the necessary resources my Logic App needs, such as its Resource Group, a unique Topic + Subscription on an existing Service Bus and a unique Storage Account.

As you can see, the bottom resourse is of type "azurerm_resource_group_template_deployment". This resource grabs the readvulns.json file, which contains the template for creating a workflow. This is the content of that readvulns.json file:

{
    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "logicAppName": {
            "type": "string"
        }
    },
    "resources": [
        {
            "type": "Microsoft.Web/sites/workflows",
            "apiVersion": "2022-03-01",
            "name": "[concat(parameters('logicAppName'), '/testworkflow1')]",
            "location": "[resourceGroup().location]",
            "properties": {
                "definition": {
                    "$schema": "https://schema.management.azure.com/schemas/2016-06-01/workflowdefinition.json#",
                    "actions": {
                        "Response": {
                            "inputs": {
                                "statusCode": 200,
                                "body": {
                                    "message": "Hello from Logic App!"
                                }
                            },
                            "runAfter": {},
                            "type": "Response"
                        }
                    },
                    "triggers": {
                        "manualTrigger": {
                            "inputs": {},
                            "kind": "Http",
                            "type": "Request"
                        }
                    },
                    "parameters": {},
                    "outputs": {}
                }
            }
        }
    ]
}

After making sure the readvulns.json file is found by the main.tf file, I run the following commands for plan + apply:

**terraform plan -out "completetest"**
**terraform apply "completetest"**

This is the output from terraform plan -out "completetest"

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:

+ create
  \-/+ destroy and then create replacement

Terraform will perform the following actions:

\-/+ resource "azurerm_api_connection" "apiConncection" {

As you can see, the error I get is: The requested resource does not support http method 'PUT'. Everything is created successfully, except for the workflow in my existing Logic App (Standard). Am I doing something wrong here?

I already tried to create other types of resources in readvulns.json but no success.

Hi Jahnavi, this is the output from "terraform --version": Terraform v1.9.7 on linux_amd64 + provider registry.terraform.io/hashicorp/azurerm v4.5.0 + provider registry.terraform.io/hashicorp/random v3.6.3 — Denver

The requested resource does not support http method 'PUT'.

The error occurs due to the conflict in the template resource deployment block within the workflow.json file. After verifying it, I found that the issue is with the input type of the workflow. It should be Microsoft.Logic/workflows rather thanMicrosoft.Web/sites/workflows.

Modify it to Microsoft.Logic/workflows in the workflow.json file with the corresponding API version as shown below.

"type": "Microsoft.Logic/workflows" and "apiVersion": "2019-05-01"

Below is the Workflow.json file after modifications:
