Hi
We support loading documents using a Uint8Array in the standalone version, and we have shared the API documentation link for loading documents with a Uint8Array . On the server side, you can convert the document to a Base64 string to load it.
For API authentication token setup, please refer to the provided documentation link to ensure proper configuration. Additionally, please let us know which API you are using to load the document so we can assist you with a more targeted solution.
Documentation Link: Authorization Token
Documentation Link for byte array: Byte Array
