Create Azure Connection API with Connection Runtime Url - azure

Question

I have a logic App (a standard logic app) that make a call to cosmos DB.
I need to store the "Connection Runtime Url" under the configuration of the logic App.
When I create the connection from the logic app designer, the connection have this property. However, when I deploy the same connection using an ARM template, the connection don't have this property.
Anyone knows how can get this property or generate it? And if possible, how to call it later in an ARM template
Thanks

Answer 1

Only API connection of kind: 'V2' can return a connectionRuntimeUrl.
You can create a cosmos db connector with the below script (bicep):
param location string = resourceGroup().location
param cosmosDbAccountName string
param connectorName string = '${cosmosDbAccountName}-connector'
// get a reference to the cosmos db account
resource cosmosDbAccount 'Microsoft.DocumentDB/databaseAccounts#2021-06-15' existing = {
name: cosmosDbAccountName
}
// create the related connection api
resource cosmosDbConnector 'Microsoft.Web/connections#2016-06-01' = {
name: connectorName
location: location
kind: 'V2'
properties: {
displayName: connectorName
parameterValues: {
databaseAccount: cosmosDbAccount.name
accessKey: listKeys(cosmosDbAccount.id, cosmosDbAccount.apiVersion).primaryMasterKey
}
api: {
id: 'subscriptions/${subscription().subscriptionId}/providers/Microsoft.Web/locations/${location}/managedApis/documentdb'
}
}
}
output connectionRuntimeUrl string = reference(cosmosDbConnector.id, cosmosDbConnector.apiVersion, 'full').properties.connectionRuntimeUrl
The url will be an output of the generated ARM
You can then set this url as an appsetting in the workflow app:
COSMOS_CONNECTION_RUNTIMEURL: <connectionRuntimeUrl>
Then in the connections.json file, you can reference this app setting:
{
"managedApiConnections": {
"documentdb": {
...
"connectionRuntimeUrl": "#appsetting('COSMOS_CONNECTION_RUNTIMEURL')"
}
}
}
Using appsettings and parameters should make thing easier to deploy

According to this discussion, a simple API connection (V1) may not have "connectionRuntimeUrl". So, to be able to see it I need to add
"kind": "V2",
in my connection Template, also as #Thomas wrote in his answer
