Add an amperand into set-body in Azure API Management

Question

I'm trying to use the set-body function and enter an & into the XML to add a parameter to a URL dynamically in a liquid template

For example

{% if {body.pagination} %}
  "url": "/api/device/select?stats=true&{{body.pagination}}",
{% else %}
  "url": "/api/device/select?stats=true",
{% endif %}

I receive the following error when trying to save the above

An error occurred while parsing EntityName. Line 31, position 114.

Is there a way to escape the & symbol, I can't use & as this is not recognised on the backend system

You have to use %26 for Url Encoding / Decoding:
https://en.wikipedia.org/wiki/Percent-encoding#Percent_character

For the correct output %26, has to be decoded by using the liquid filter.-

{% if {body.pagination} %}
  "url": "{{"/api/device/select?stats=true%26" | UrlDecode}}{{body.pagination}}",
{% else %}
  "url": "/api/device/select?stats=true",
{% endif %}
