One screen to view all a logic app's inputs & outputs

Richard Scannell 406

How do search ALL the inputs & outputs from ALL the steps in one go. I know how to look at the inputs & outputs from a single named step in a logic app. I need to do this to find the step where a particular variable is generated.

I have inherited a large & complex logic app, which is failing in a step that uses a code for an API, which is failing with the message that the code is invalid. The code is generated in an earlier unknown step and I need to find out where the code is generated. Many thanks.

Hi @Richard Scannell ,

Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

If you want to view all the inputs and outputs of a Logic App to trace where a specific variable is generated, here are some easy methods you can use:

Go to the Azure Portal, find your Logic App, and look under the Run History section. Select the failed or relevant run you want to inspect, then click on it to see the details. You can review the step-by-step execution.

For each step, click on "Show Raw Inputs/Outputs" to see the data being passed at that point. This method lets you check inputs and outputs for each step, but it can be a bit slow if your Logic App has many steps.

If you have Application Insights set up, you can search across all steps to find your variable. Go to Application Insights in the Azure Portal, use the Logs section, and run a Kusto Query Language (KQL) query to trace the variable through different steps.

If you're comfortable with APIs, you can use the Workflow Run Actions API to get inputs and outputs for each action in your Logic App. This lets you automate the retrieval process. You can also open the Logic App in the Azure Portal, switch to Code View, and check the JSON file in a text editor like VSCode or Notepad++.

Look for your variable in the inputs and outputs sections of the JSON. This will help you understand where it’s generated and how it moves through the steps.

If your Logic App has many steps, consider exporting the run history to a CSV or JSON file. After exporting, you can search the file for your variable using any text editor or spreadsheet tool. This method allows you to quickly scan through the entire execution history and find where the variable is created.

I hope this helps! Let me know if you have any questions.

Hi Shireesha Eeraboina, thank you for the suggestions. I have checked raw outputs, and whilst it shows the data , it does require knowing what the step is. The problem I had is that the step to set the variable is not the one triggering the error. I have not been able to get application insights working for this, yet - but it looks like it would be useful.

I am most interested in the suggestion to export the run history to csv or json, how do I do that? Does that depend on application insights, or do I need a specific role to do that - I can't see any obvious button to do that? Thank you again for your help

Hello @Richard Scannell ,

I'm glad my previous response was helpful. To export the run history to a CSV or JSON file, you don't necessarily need Application Insights. You can do this directly from the Azure Portal.

Go to the Azure Portal and navigate to the Logic App then click on the "Overview" tab to see the run history.

Select the specific run you want to export, this will open the run details and in the run detail's view, look for an option or button like "Download" or "Export". Sometimes, these options are available under the more options menu.

If this option is not directly visible, you can also use PowerShell to export the run history.

You don’t need any specific roles beyond having access to the Logic App and the permissions to view its run history. If you don’t see the "Download" button or encounter any permission issues, you might need to check with your Azure admin.

Once you have the JSON or CSV file, you can use any text editor or spreadsheet application to search for your variable easily.

I hope this helps! Let me know if you have any further questions or need additional assistance.
