Meta Conversions API Gateway is the newest approach to setting up Conversions API, and it looks like it offers the easiest implementation process yet. Taking advantage of a cloud-based and secure connection between advertisers and Meta, Conversions API Gateway doesn’t require you to set up event deduplication, and can send user parameters or events from a server. Additionally, it can support multiple domains and pixels within a single instance, even when these assets are managed by different Business Manager accounts.

This blog post discusses what Conversions API Gateway is, and its advantages and disadvantages over server Google Tag Manager implementation of Conversions API. It will also include information on how to set up Conversions API Gateway using hosting. It only takes one minute!

Meta and server-side tracking

The need for server-side tracking has increased due to changes in the way that browser tracking is regulated, and Meta was among the first to offer a solution to this challenge. Its server-to-server technology was released before the server Google Tag Manager was even in a public beta. 

The digital advertising landscape has been rapidly evolving, with increasingly stringent tracking restrictions like Intelligent Tracking Prevention and Ad Blockers on the rise. 

As a result, Meta advertisers have experienced a significant decrease in success rates for paid campaigns. However, with adequately implemented Conversions API, they have been able to improve conversion rates and get more accurate results from paid ads, even with tightening tracking restrictions.

The main reason why Conversions API helps improve campaign results is that server-to-server tracking is more reliable than browser tracking. When ITP limits cookies or Ad Blocker prevents Meta Pixels from firing, server tracking still works. It delivers valuable data, which helps attribute conversions to campaigns and create quality custom audiences. 

Even with such a huge advantage, the time to implement Conversions API could be faster. Installing Conversions API can be time-consuming and requires technical skills that can be a barrier for some advertisers. Despite this, Stape’s agency has been mainly working with server-side tracking and Conversions API. For us, on average, it takes about 15 hours to implement Conversions API using the server Google Tag Manager. 

This is where Conversions API Gateway comes in. It’s the fastest solution for implementing Meta server-side tracking, and it does not require any specialized knowledge. 

How Conversions API Gateway works

The critical feature of Conversions API Gateway is its environment. Each Conversions API Gateway instance requires a cloud server to run all communication processes between Meta Pixel and Conversions API. Check Meta documentation describing how Conversions API Gateway works to understand it in more detail.

After the Meta Pixel is connected to the Conversions API Gateway environment, it will use web events to track data from the server. Therefore, before implementing Conversions API Gateway, it's essential to ensure that web events are 100% accurate and receive all the required user and product information.

With Stape, setting up and hosting Conversions API Gateway is simpler than ever. All you need to do is create a Stape account and set up Conversions API Gateway inside Stape. Then, just connect the required Meta Pixels to the Conversions API Gateway environment.

Conversions API Gateway pros and cons


1. Low price. hosting for Conversions API Gateway costs $10/month per pixel or $100/month for unlimited pixels. We also offer a 7-day free trial.

Additionally, Conversions API Gateway is the most straightforward way of setting up Conversions API, meaning you can save hundreds or thousands of dollars compared to manual Conversions API implementation.

2. Easy setup. You don't need to hire developers or tracking specialists to set up Conversions API Gateway. The steps to set it up are simple compared to Conversions API implementation; it can take less than 1 minute to implement and can be done by someone without technical skills. 

3. No maintenance.  Conversions API Gateway updates are installed automatically. There is no need to spend time manually updating settings or servers. Even when you add a new event, all you have to do is set up proper web tracking and Conversions API Gateway will start tracking events from the server automatically. 


1. New. Conversions API Gateway is new; most likely, Meta will roll out new functionality and update the existing one, so it makes sense to prepare for some changes to its features.

2. No support for other platforms. If you want all the benefits of server-side tracking, server Google Tag Manager might be a better solution. You will still need an instance of Google Tag Manager to manage server Google Analytics, Google Ads, etc.

Frequently Asked Questions:

1. Conversions API  Gateway does not see my events.

Stape's Conversions API Gateway hosting is a server instance in the GCP cloud environment, which sends web events through a reliable server-to-server connection to Meta. Every time the Meta Pixel is fired from the browser, the events will be sent to Meta Pixel and Conversions API through a secure connection.

If you see the inconsistency of web and server events, ensure no additional integration might send data to either Meta Pixel or Conversions API, such as third-party apps, plugins, integration through the Google Tag Manager, etc.

2. Are there any limits for the subscription plans you offer?

You get up to 10 million events for $10/month and up to 200 million events on a $100/month plan.

3. I see a 404 error in the console after configuring the data routing subdomain. 

It might take up to 30 minutes to process new DNS settings. First, please ensure that the DNS settings you've set up are correct. You can use this tool to verify DNS settings. For example, if you use Cloudflare, the settings should look like the screenshot below.
