Boxalino Convert Endpoint

As part of a new newsletter integration strategy, the recommended products/content details (pictures) will be generated live, upon endpoint use.

A sample of the use of the convert (live) endpoint is used on our Shopware6 QA server: http://auto-qa.bx-cloud.com/Newsletter/


This is how the final link (shared with Boxalino) is:

https://convert.bx-cloud.com/img/stream?cropWidth=400&cropHeight=655&source=http://auto-qa.bx-cloud.com/boxalino/newsletter/product/en/<product-id>

Set the properties viewportWidth/viewportHeight, cropWidth/cropHeight ,source  and converter (optional) values.

About the CONVERT endpoint


The public service (convert.bx-cloud.com) is a play framework application that performs conversions. Currently, it implements wkhtmltoimage to convert html pages to images (opensource)

html to image conversion

Api paths (GET):

Path

Functionality

Path

Functionality

/img/stream?[...]

generates and streams the image

/img/redirect?[...]

generates and redirects to the /img/get endpoint

/img/get?[...]

public endpoint, only supports retrieval

Note that the /img/get api should never be directly used, because the result image will eventually be deleted (typically after 24 hours).

Use the /img/redirect api instead to always ensure a fresh image.
