Unable to make app live (using REST) #stuck in sandbox

[SeemusDesign]

No matter how many times I change from Sandbox to Live, it doesnt 'stick'. I get an error: invalid_client (amongst other things) (see below).

I also include the following apiContext:

$apiContext->setConfig(
array(
'log.LogEnabled' => true,
'log.FileName' => 'PayPal.log',
'log.LogLevel' => 'DEBUG',
'mode' => 'live'
)
);

I also have business account.

But no change.

Am I missing a step?

Thanks

Hello,

You don't "change" from sandbox to live, both environments are available at all times when viewing a REST application. The "toggle" is only there to allow you to move from the default sandbox REST credentials page to the live REST credentials page.

"Invalid_client_id" is returned either because there is an issue with the "client_id" and "client_secret" credentials your attempting to use or your submitting the requests to the incorrect environment (ie: attempting to use a sandbox client_id and client_secret and you submit the request to our live environment.

## Request Access Token Endpoints

## Create Payment Endpoints
