What are Postback and Backlink URLs, and How to Use Them in Affiliate Marketing

In affiliate marketing, Postback URLs and Backlinks are often considered advanced tools. We at Adsterra strongly object to this point of view. Prompt and informative tracking is something that should be an initial part of any affiliate marketing activity, whether it is a short-term, one-GEO campaign or a multi-GEO promo strategy. 

Both beginner and pro affiliates should have a clear picture of measuring their efforts’ efficiency and assessing traffic sources. An excellent topic for a tutorial, isn’t it? This time we are going to puzzle out some common difficulties related to understanding how Postback URLs’ and Backlinks work.

What is a Postback URL in affiliate marketing?

Postback URLs are URLs through which the affiliate network or program sends data about conversions to the tracker, and it, in turn, sends it to the traffic source.  

Through URL Postback parameters, the affiliate network informs the affiliate marketer about the completed conversion. In turn, a tracker, by activating the URL Postback of the traffic source, reports about this event.

Postback URLs allow servers to communicate directly with each other and transfer information from server to server. That’s why Postback is also called S2S Postback.

Generally, you can track conversions in two ways:

  • using Postback URLs;
  • using pixel tracking.

Most affiliate or CPA networks use Postbacks to produce reports on conversions. Traffic sources are usually also technically capable of receiving conversions via Postback URLs. The only exceptions are Google and Facebook, which track conversions using their pixels. Trackers typically allow you to use both ways.

How does the Postback URL tracking work?

Once laid out, the Postback topic becomes transparent. Let’s see what happens under the hood.

You can see from the infographics below that there are two reverse data transfers. The affiliate network sends conversion data back to the tracker and the tracker back to the traffic source.

Conversion tracking explained

When a user clicks on an ad, the traffic source (like Adsterra ad network) generates its click ID value. The traffic source then sends this click ID to the tracker. The tracker generates a unique identifier based on the information received from the traffic source and assigns it to each click of that visitor. Next, through the tracking link, the tracker substituting the click ID value transmits the unique identifier of the click to the affiliate network.

If a conversion takes place, the affiliate network activates the Postback URL for the tracker, which will indicate the click ID of this click.

In the postback URL, the affiliate network passes the unique click ID back confirming that a particular visitor initiated the conversion. In other words, the tracker only accepts the Postback URL from the affiliate network, which contains its click ID value.

When the tracker receives a Postback URL from an affiliate platform with its click ID, it will activate the traffic source Postback URL and send it back with the click ID value. The postback URL of the traffic source must contain precisely the click ID value that was passed on to the tracker via the campaign URL. 

You can get other parameters in the Postback as well: the payment amount, the transition time, the order number, and so on. The information will depend on what macros (or tokens) you select.

An example of a Postback URL that can be used in affiliate marketing 

Let’s inspect an example of a Postback URL and see which parameters it operates.

https://domain.com/postback?subid={sub2}&payout={money}&currency={currency}
  • “domain.com” is the URL of the offer that an affiliate marketer enters.
  • “?” is the symbol that separates the main body of the link from the tracking parameters.
  • &” is the symbol that separates different tracking parameters.
  • subid (the click’s unique code), payout, currency — these are tracking parameters that transfer values. They are unique for each tracker.
  • {sub2}, {money}, {currency} — these are the affiliate network’s tokens that will be replaced with values when the link is activated. They are unique for each affiliate network. 

As soon as the user performs the target action, the affiliate network platform will activate this URL, and the tokens will be replaced with specific information.

The activated Postback will look like this:

https://domain.com/postback?subid=1111111&payout=1&currency=usd

To summarize, the tracker and traffic source only provide templates.

To get a ready-made Postback URL, you need to match the tokens of target platforms, for example, an affiliate network and a tracker. In the tracker, the unique click code is subid. 

On the affiliate network, the value of the unique click is transmitted by the {sub2} token, which means that in the postback link, you need to write subid = {sub2}.

https://domain.com/postback?subid=REPLACE&payout=REPLACE&currency=REPLACE

Why Postback URLs tracking is important in affiliate marketing

All platforms involved in conversion tracking keep track of incoming user clicks.

  1. Traffic sources get paid for the clicks.
  2. Marketers, without counting all clicks, will not be able to cross-check with the affiliate network the exact number of conversions, and as a result, may not get their due payment.
  3. Affiliate networks must understand how much money to ask from the advertiser, how much to pay the affiliate marketer, and what commission to withhold. That’s why all platforms give each user click a unique identifier. In other words, each click has its unique value.

A backlink is a tool based on the Direct Link algorithm that automatically selects the most suitable offer for the user who came through the link.

Thanks to Backlinks, no traffic that doesn’t correspond to the tested offer by any parameter is lost. Your traffic doesn’t go back to the traffic source back but instead distributes between the best-matching offers.

And you don’t necessarily need to handpick these offers or use multiple links. Everything can be done within a working campaign by creating just one Backlink. Using Backlink allows you to get maximum income and significantly save precious time.

Within a campaign, some traffic may not suit the offer: wrong GEO, wrong operator, wrong device type, any limits set by the advertiser. 

Backlink allows you to find a place for these, at first glance, useless visitors. It will automatically determine where the user came from, which device, which operator he has, what type of connection and direct them to a reasonable offer.

The Backlink system suggests offers based on the audience behavior, directing users to the best-selling landing pages. As a result, the best offer will be found for absolutely all types of traffic.

It is most efficient to use Backlink for residual traffic. The best choice is to create a stream in the tracker where users who do not meet the criteria of the main offer will be sent.

You can, of course, use Backlink as your primary monetization tool. But then you need to consider that the offers often change, have different payouts, and may not precisely correspond to the target audience of the tested offer. The Backlink doesn’t allow you to select offers or determine which one is the one that converts best.

In this case, you can consult your Adsterra Account Manager or online support about what results in more conversions and create a particular ad campaign for that offer.

If you want to use a Backlink in your affiliate marketing campaigns with Adsterra CPA Network, sign up with any service offering a Backlink URL and insert it into your Adsterra offer settings. All stats and payouts earned from the Backlink are found on your dashboard of the service you use.
