Run a Flow

Now that you have a Workspace and a Flow, you can run your Flow.

You can first run your flow without any data transformations with some simple input data.

We’ll use the following input data:

{                             
   "message": "Hello lam",   
   "foo": "delete me",     
   "http_status": "200"   
}                        

1. From your Workspace Dashboard, click Create Flow on the bottom left of the Flows table.
2. Give your Flow a name and a description and click Create Flow.
3. Add input data for the test by pasting the JSON above into the Input field.

We’ll now add a simple transformation to our Flow.

# Remove some fields
del(.foo)

# Add a timestamp
.timestamp = now()

# Parse HTTP status code into local variable
http_status_code = parse_int!(.http_status)
del(.http_status)

# Add status
if http_status_code >= 200 && http_status_code <= 299 {
    .status = "success"
} else {
    .status = "error"
}

Our Flow will take the input data and transform it into the following output data:

{                             ->   {  
   "message": "Hello lam",            "message": "Hello lam",
   "foo": "delete me",        ->      "status": "success"
   "http_status": "200"               "timestamp": "2024-01-29T12:00:00Z"
}                             ->   }

3. In the Flow Editor, add a program to your Flow in Lam, and click Update Flow.
4. Click Run Flow, and you should see your transformed output data.

Amazing! 🎉 You’ve just run your first Flow in Laminar.

Now you’ll want to run your Flow with real data using Laminar’s API.
