Hi,
Base64 Decode & Encode Filters by dinsley · Pull Request #1450 · Shopify/liquid · GitHub shows that the liquid syntax now support
{{ 'some data' | base64_encode }}
But it does not work in auth0 email templates. Do you know what version is used by Auth0?
Some background on this requirement:
We want to add segment pixel tracking in our emails. Tracking Pixel API | Segment Documentation . For that we need to send a base64 of some user metadata.
Thanks.
