I’m invoking an email template (that we created in your dashboard) via your Single Send API, and there several custom fields/properties tokens within the template were misspelled. So I corrected them, and Saved, then hit Next several times, until Update appeared, then clicked that, and invoked the API to resend that email template and again got the same error:
Mismatch in custom properties between template and request - Custom properties in the template, but not in the request: d_fname, a_fname…
but I did a ViewSource and those corrected field names are NO longer in the template, but just for fun, I repeated the Save/Update steps (and even had your support team verify that your meta-data shows it actually saving), and still I get the ‘mismatch error’ using the old, now non-existent field names ( custom.d_fname, custom.a_fname, etc…)
We have many other email templates that we successfully invoke via SS API and get sent to recipients. So, I think one of 2 things might be happening: either the Save/Update functionality is broken b/c of some strange scenario on our template, OR you maybe use a CDN and it’s caching the template…but this error has been persisting for over 24hrs, and I’ve never seen a CDN cache that long.
Any other ideas? I can PM you details on the template ID and our account if needed.
