Trigger Azure Data Factory Pipeline from Logic App w/ Parameter

Question

Let me preface that I\'m a noob to Logic Apps and Data Factory. Anyways, I\'m currently working on an integration and one part of it is that I need to trigger a pipeline in

Answer 1

You can use the body property of the logic app's "Create a pipeline run" action to pass parameters to the pipeline. As always, be careful because not only is this action in preview but I also couldn't find this solution in any MS documentation. I just made an educated guess based on how other similar actions are formatted.

Example:

"Run_my_pipeline": {
  "inputs": {
    "host": {
      "connection": {
        "name": "@parameters('$connections')['azuredatafactory']['connectionId']"
      }
    },
    "method": "post",
    "body": {
      "param1": "myParamValue",
      "param2": "myParamValue"
    },
    "path": "...",
    "queries": {
      "x-ms-api-version": "2017-09-01-preview"
    },
    "authentication": "@parameters('$authentication')"
  }
}

as I said in the comment I create a workaround with azure functions. Azure functions and logic app work well together. On this link you can see how to create and manage pipelines with .net https://docs.microsoft.com/en-us/azure/data-factory/quickstart-create-data-factory-dot-net

If you already have ADF and pipeline, you just want to run it (with pipelines) then you can just

Dictionary<string, object> parameters = new Dictionary<string, object>
       {
           {"BoxSerialNumbers", req.BoxSerialNumbers},
           {"StartDate", req.StartDate },
           {"EndDate",req.EndDate },
           {"Recipient", req.Recipient }
       };//this is how you add initialaze parameters

        var client = Authenticate(); //Authentication with azure
        log.Info("Creating.");
        CreateRunResponse runResponse = client.Pipelines.CreateRun(resourceGroup, dataFactoryName, "pipeline1", parameters);//run pipeline, you can do this async (it's better)
        log.Info("Created.");
        var response = new HttpResponseMessage();
        if (client.PipelineRuns.Get(resourceGroup, dataFactoryName, runResponse.RunId).Status.Equals("InProgress"))
        {
            response = new HttpResponseMessage(HttpStatusCode.OK)
            {
                Content = new StringContent(runResponse.RunId, Encoding.UTF8)
            };
        }
        else
        {
            response = new HttpResponseMessage(HttpStatusCode.BadRequest)
            {
                Content = new StringContent("Pipeline didn't started", Encoding.UTF8)//just some validation for function
            };
        }
        return response;                                               


    public static DataFactoryManagementClient Authenticate()
    {
        var context = new AuthenticationContext("https://login.windows.net/" + tenantID);
        ClientCredential cc = new ClientCredential(applicationID, authenticationKey);
        AuthenticationResult result = context.AcquireTokenAsync("https://management.azure.com/", cc).Result;
        ServiceClientCredentials cred = new TokenCredentials(result.AccessToken);
        return new DataFactoryManagementClient(cred) { SubscriptionId = subscriptionID };
    }

So in the request, you can pass your parameters from a logic app, with runId you can check status. Then in logic app just simple HTTP request to call this function. Hope this help someone.

I used DraganB's solution but the call signature on

CreateRunResponse runResponse = client.Pipelines.CreateRun(resourceGroup, dataFactoryName, "pipeline1", parameters);

has changed. Minor edits make this work perfectly:

CreateRunResponse runResponse = client.Pipelines.CreateRun(resourceGroup, dataFactoryName, "pipeline1", parameters: parameters);

Here's the function for anyone that needs it.

[FunctionName("DatafactoryShim")]
    public async static Task<HttpResponseMessage> Run(
        [HttpTrigger(AuthorizationLevel.Function, "post")]
        HttpRequestMessage req,
        ExecutionContext context,
        TraceWriter log
    )
    {
        string messageBody = await req.Content.ReadAsStringAsync();

        BlobToDatalakeFactoryParameters postValues = JsonHelper.ToClass<BlobToDatalakeFactoryParameters>(messageBody);

        Dictionary<string, object> parameters = new Dictionary<string, object>
        {
            {"blobContainer", postValues.BlobContainer},
            {"blobFolder", postValues.BlobFolder },
            {"relativeDatalakeFolder", postValues.RelativeDatalakeFolder },
            {"modelType", postValues.ModelType }

        }; //this is how you add initialaze parameters

        var client = Authenticate(); //Authentication with azure

        string resourceGroup = ConfigurationManager.AppSettings["resourceGroup"];
        string dataFactoryName = ConfigurationManager.AppSettings["dataFactoryName"];
        string pipelineName = ConfigurationManager.AppSettings["pipelineName"];

        Console.WriteLine("Creating pipeline run...");
        CreateRunResponse runResponse = client.Pipelines.CreateRunWithHttpMessagesAsync(
            resourceGroup,
            dataFactoryName,
            pipelineName,
            parameters: parameters).Result.Body;
        Console.WriteLine("Pipeline run ID: " + runResponse.RunId);

        var response = new HttpResponseMessage();

        if (client.PipelineRuns.Get(ConfigurationManager.AppSettings["resourceGroup"],
            ConfigurationManager.AppSettings["dataFactoryName"], runResponse.RunId).Status.Equals("InProgress"))
        {
            response = new HttpResponseMessage(HttpStatusCode.OK)
            {
                Content = new StringContent(runResponse.RunId, Encoding.UTF8)
            };
        }
        else
        {
            response = new HttpResponseMessage(HttpStatusCode.BadRequest)
            {
                Content =
                    new StringContent("Pipeline didn't started", Encoding.UTF8) //just some validation for function
            };
        }

        return response;
    }
