The v1.1 Words REST API has stopped working suddenly

I realise it’s probably a very old API, but the v1.1 REST API for Aspose Words Cloud is what our SaaS platform uses for document generation and we didn’t realise it was about to be retired!

I’ve just found an email ("Action Required: Migration Needed) from sales@aspose.cloud sent to us about a week ago, but this says we have until 16 November 2025 to migrate to the latest version.

Today, I’ve found our calls to the v1.1 document conversion endpoint is failing with a response like this?

{“Error”:{“Code”:“UnsupportedApiVersion”,“Message”:“The HTTP resource that matches the request URI ‘http://api.aspose.com/v1.1/words/[REMOVED].docx?format=pdf&folder=DocTemplates_DEV&appSID=[REMOVED]&signature=[REMOVED]’ does not support the API version ‘1.1’.”}}

I will ask the responsible team why this happened.
