Email recommendations widget APIs v2

👍

Prerequisite

For detailed information on the Email Recommendations feature and its use-cases, go through its feature guide.

What are Email Recommendations APIs?

The Email Recommendations APIs are same as the Recommendations and Pathways API v2, for all the 5 widget types, except that each API can now be either a Proxy API or an Image API.
The response formats of the Email Recommendations APIs are different from the Recommendations APIs. Unlike the latter, where we get a JSON response containing details of multiple products in that widget, the Email Recommendations APIs' response is a redirect (HTTP 302) to either a Product Description Page or an Image of a single product.

📘

Proxy and Image APIs

The Proxy APIs redirect to the Product Description Page of the product and Image APIs redirect to the Image of the product.

The email should have a template defined, which can then be integrated with different Email Service Providers.

Here is a sample email template:

<html>
<body>

In this template, we first decide the number of desired image slots, let's say, 3. For each slot, we have to define a hyperlink HTML tag (<a>) and an image HTML tag (<img>). The hyperlink tag will point to the Proxy API call and Image tag will point to the Image API call defined above.

For each image slot, the API calls are the same, except that we update the start parameter. start=0 denotes the first product of the recall set, start=1 denotes the second product of the recall set, and so on.

Filtering support

Email Recommendations APIs (both Proxy and Image) support the filtering capabilities of Recommendations and Pathways APIs.

Sending additional parameters to track email campaigns

Email Recommendations Proxy APIs allow you to track email campaigns by passing additional parameters. You must follow the below guidelines to pass such parameters:

  1. The additional parameters must start with the prefix brtrk_. We will ignore the parameters with an incorrect prefix. For instance, the parameter is utm_campaign=special_holiday; with the prefix, it becomes brtrk_utm_campaign=special_holiday.

  2. You can pass up to 10 additional parameters. If more than 10 brtrk_ prefixed parameters are passed, we ignore them.

  3. Parameter names and values must be alphanumeric. The only special characters supported are underscore (_) and hyphen (-). If any other characters are passed, we will ignore the parameter.

  4. Each parameter name and value can be a maximum of 100 characters. If they exceed this limit, we will ignore them.

  5. You don’t need to implement any mechanism to remove prefixes from parameters. Our system identifies additional parameters and removes the prefix. Refer to the sample request and response.
