Neutrinos Engineering Tips #1: Mastering HTTP Requests Using Switch Logic

:white_check_mark: Centralizing HTTP Requests in Neutrinos SSD

Managing HTTP requests in Neutrinos SSD can quickly become messy if each API call has its own request node and response logic. A better approach is to centralize your HTTP handling. Here’s how :backhand_index_pointing_down:


:file_folder: Folder Structure

Under the util folder, create a new SSD flow named:
http

This flow should:

  • Accept a generic request object
bh.local.reqObject = {
  method: 'POST',                        // HTTP method: 'GET', 'POST', 'PUT', 'DELETE', etc.
  url: 'https://api.example.com/data',   // Target API endpoint
  payload: { }                          // Request body (for POST, PUT) , 
  headers: {                             // Optional: custom headers
    'Content-Type': 'application/json',
    Authorization: 'Bearer <token>'
  },
  isMock: false,                         // Set to true to return a mock response

};
  • Use a Switch node to check whether it’s a live API call or a mock
  • Route the flow accordingly:
    → If mock is required (e.g., testing, API not yet available), return a mock response
    → Otherwise, make an actual HTTP call

:brain: Why This Is a Best Practice?

:white_check_mark: Improved Debugging
All your API requests and responses go through a single point. Makes logging and debugging a breeze.

:white_check_mark: Easier Testing with Mocks
For projects in early stages or backend delays, easily enable mock responses by just setting a flag in your request.

:white_check_mark: Cleaner Codebase
No need to create multiple similar HTTP Request nodes across your SSDs. Just call the centralized flow.

:blue_square: Flow Entry → :orange_square: Switch → :red_square: Mock Response / :green_square: HTTP Request → :red_square: Script

This structure helps decouple mock vs real logic at one place.

:speech_balloon: Let me know if you want the reusable flow snippet or want to contribute to the series with your own patterns!

This is awesome! :fire::fire::fire: @Shamnad_KS I haven’t tried centralizing HTTP calls in SSD before, but this looks way cleaner. Keen to give it a shot.

@Shamnad_KS This is a good approach if you have few 3rd party API integrations which follow the same integration pattern. But every approach has trade-offs.

Problem 1: Hard to debug

When something breaks in production, all errors look the same. You can’t easily tell which specific API call failed or where it came from.

Problem 2: there will be scenarios where different APIs need different setups
Some APIs use API keys
Others use OAuth tokens
Some put auth in headers, others in the URL

Trying to handle all these in one place may get messy in the long run, if you have different types of 3rd party APIs. So we need to keep this in mind when implementing this centralized flow.
there is another alternative approach. Instead of one big HTTP node, we can group them by type:

  • One for payment APIs (Stripe, PayPal etc)
  • One for CRM APIs (Salesforce)
  • One for internal APIs

@sonu.suresh Thank you for the thoughtful input — completely agree with your points. :raising_hands:

This pattern is definitely more suited for scenarios where the APIs follow a common structure or during early phases of development where mocking and centralized debugging help speed things up.

You’re right — as the number and complexity of integrations grow, handling everything in a single flow can become harder to maintain, especially with varying auth mechanisms or headers.

Grouping flows based on API domains like payments, CRM, internal services, etc., is a great strategy. That way, we retain structure while allowing flexibility per integration type.

Appreciate you highlighting the trade-offs — it’s important for teams to consider these when adopting or evolving the approach. Will add a note on this in future posts too. Thanks again!:star_struck::folded_hands:
