Quick question about securing outbound API calls from within a CXone Studio script. I am trying to invoke a downstream service using the GetRESTProxy snippet, but I need to first acquire an OAuth2 access token using the client_credentials grant type.
The challenge is that GetRESTProxy does not appear to have a built-in method for performing the initial POST to /oauth/token. I have attempted to chain a GetRESTProxy call to fetch the token, extract the access_token string using GetJSONValue, and then inject it into the Authorization header of the subsequent business logic call. However, the token retrieval step consistently fails with a 401 Unauthorized error, likely because I am mishandling the Basic Auth header generation within the snippet’s limited string manipulation capabilities.
“The
client_credentialsgrant requires the client_id and client_secret to be passed as Base64-encoded Basic Auth credentials in the Authorization header of the POST request to the token endpoint.”
Is there a recommended pattern for handling this two-step authentication flow entirely within Studio? Or should I be routing this through a middleware layer to handle the token exchange before the script execution? Here is my current attempt at the token fetch configuration:
{
"method": "POST",
"url": "https://api.nice.incontact.com/oauth/token",
"headers": {
"Content-Type": "application/x-www-form-urlencoded"
},
"body": "grant_type=client_credentials&scope=api"
}
