Upload a Document to ADOBE Document cloud from API

[yamunadevir3335016]

I have used JWT web token to create access token for the API services.

and called https://dc-api.adobe.io/discovery from postman, which returned all methods in the API.

I have used the asset POST call to upload a document and getting the following error:

I used Access header: application/vnd.adobe.dc+json;profile="https://dc-api.adobe.io/schemas/asset_v1.json", and Bearer token.

{

    "error": {

        "code": "CloudError",

        "message": "Unauthorized"

    }

}

Please advise.
