In this guide
- A server container can forward events to apps with HTTP request tags. It is cheap and fast for simple jobs.
- A workflow tool such as Zapier or Make is better for multi-step logic, retries and many app connectors.
- Use the container for event-to-endpoint, and a workflow tool for business processes.
Marketers use Zapier-style tools to connect forms, shops and CRMs. A server container can do some of the same jobs: when an event arrives, send a request to another app. For the right jobs it is simpler and cheaper. For others it is the wrong tool. This page compares them honestly. See webhook servers, Slack notifications and other recipes and interesting use cases.
What each is good at
| Job | Server container | Workflow tool |
|---|---|---|
| Send each purchase to an endpoint | Good: one tag, no per-task fee | Works, may cost per task |
| Branching logic and conditions | Limited to triggers | Good |
| Retries and queues | Limited. A failed request is lost unless you build handling | Built in |
| Hundreds of app connectors | Needs HTTP requests or templates | Good |
| Non-technical editing | Requires Tag Manager knowledge | Visual editors |
| Cost at high volume | Fixed hosting plan | Per task or per run |
| Privacy control | Strong: you control the data | Depends on the vendor |

When to use the container
- The trigger is already an event your container sees (purchase, lead).
- The action is one HTTP request.
- Volume is high and per-task fees would add up.
- You want to strip or hash fields before the data leaves.
When to use a workflow tool
- The process has several steps or decisions.
- You need retries and error handling.
- Non-technical people maintain it.
- The app has a ready connector.

A combination
A common pattern: the server container receives the purchase and sends it to ad platforms and analytics. A single HTTP request tag also posts it to a workflow tool's webhook, which then runs the multi-step business process. Each tool does what it is best at. Open Tracked's CRM pipeline also includes workflow automation for lead stages, and its server container can receive webhooks from other systems.
Cautions
A realistic example
A small shop wants a message in Slack for every order above $500 and a row in a spreadsheet for every lead. It used to pay a workflow tool per task and hit the plan limit every month. It adds two HTTP request tags to its server container, triggered by the purchase and lead events, with a condition on the order value, and posts to a Slack webhook and a spreadsheet script. The tasks cost nothing extra, the container already had the data, and it can strip the customer's name from the Slack message. When the shop later needs a process with approvals and reminders, it keeps that in a workflow tool, fed by a webhook from the container. Each tool ended up where it fit.
Orders from your store, back to the ad that earned them
Your store sends the order once. Open Tracked passes it on to each ad platform, cleaned and deduplicated.
Frequently asked questions
Can a server container replace Zapier?
For simple event-to-endpoint jobs, yes. For multi-step workflows with retries, a workflow tool is better.
How do I send an event to an app from a server container?
With an HTTP request tag or a template for that app, triggered by the event.
What happens if the request fails?
It is not retried unless you build handling. Log and alert on failures.
Is it cheaper than a workflow tool?
At high volume, often, because hosting is a fixed plan.
Can I use both?
Yes. Post the event to a workflow tool's webhook from the container.
Do I need spreadsheets to read my results?
No. Once tracking is live, the Open Tracked analytics shows spend, revenue, ROAS and profit, and you can ask Ari, the built-in AI assistant, questions about your own numbers in plain words. Ari's allowance depends on your analytics plan.
Is Open Tracked different from Open Track or Open Space Track?
No. Open Tracked is the official name of our server-side tracking platform, and the website is opentracked.io. Many people search for it as Open Track, OpenTrack or Open Space Track. All of them lead to the same product: server-side Google Tag Manager hosting, first-party analytics and a CRM pipeline.
Fix your tracking at the source
Open Tracked hosts your server-side Tag Manager, keeps first-party cookies alive and shows what each ad is really worth.
