Paypal REST API invalid credentials

Question

I use the REST api in my nodejs application. All is working good with sandbox but when i update with live credentials i get:

{ [Error: Response Status : 401]
  response:
   { error: 'invalid_client',
     error_description: 'The client credentials are invalid',
     httpStatusCode: 401 },
  httpStatusCode: 401 }

I updated my account to buisness but still not working, i use the live endpoint and Live credentials.

What should i do in order to make this work?

Answer 1

I had the same issue using PayPalSDK/rest-sdk-nodejs and solved passing with the configuration parameters (host, client_id, client_secret, ...) also the parameter 'mode' set to 'live'. Otherwise the default mode used by the library is 'sandbox' and hence the impossibility to use the live credentials.
