    It probably means your appKey or appSecret is wrong.

    In your code there is "MyaccessToken", how did you generate it?

    Hello Tyler,

    MyaccessToken I have generated using RingCentral OAuth 2.0 Authentication.

    Do you mean I am using wrong appKey or appSecret while generating access token ?

    Thanks,

    Could you please provide the following:

    1. Are you using the RingCentral JS SDK? If yes, which version?
    2. Description of the 'endpointId' variable's assigned value
    3. The complete error response with headers/body from this request

    This will help in figuring out what is happening here.

    I am not using SDK.
    I have entered endpointId value which I got it with access token.

    Below is the error I am facing.

     {
      "error" : "invalid_client",
      "error_description" : "Authentication header value is malformed"
    }



    Please do let me know if you need more information.

    You will need to view the documentation, because Tyler is correct, you are using the incorrect Authorization Header key:value. https://developers.ringcentral.com/api-docs/latest/index.html#!#RefRefreshTokenFlow

    What this means is in your example you set the "Authorization: Basic {{myAccessToken}}", but this is incorrect because you SHOULD NOT be using your "access_token" as this value, you should instead be using the result of Base64 encoding your {{appKey}}:{{appSecret}} (which is the same value you used to obtain the 'access_token' initially).

    Also, please pay special attention to the description for endpointId...
    If not specified, the previously specified or auto-generated value is used by default

    Mahesh More,have you get the solution.Have you get the solution to refresh the access token?

    Yes you don't need to put access_token in Authorization header. All you need to put is Base64 format of clientId and client secret as follow:

    Authorization Basic <clientId:clientSecret in Base64>

    Access_token are need to pass to the actual main APIs as type Bearer to get the response
