Every endpoint is documented in the sidebar with an interactive playground — add your API key and send a real request from the page.
https://dashboard.omnia-voice.com/api/v1 is an alias for the same service and continues to work. Prefer api.omnia-voice.com for new work.

​
Conventions

Authentication — X-API-Key on every request. See Authentication. Content type — application/json for request bodies. Single resources return the object directly:
Collections return data plus pagination:
Pagination — most collections use ?page=1&limit=50 (default 50, maximum 100) and return a pagination object. /calls is the exception: it uses cursor pagination to match the underlying voice provider — ?cursor=...&pageSize=50. Follow the cursor returned by the previous response rather than incrementing a page number. Errors are consistent:
Full status and code table in Authentication. Partial updates — resources are updated with PATCH, not PUT. Send only the fields you are changing. There are no PUT handlers on this API.
