Cannot access Paypal Sandbox Accounts

Question

PayPal:

Cant access paypal sandbox - if trying to appraoch directly, you are being redirected to the paypal main site.

If trying to reach the sandbox via the paypal developer site, browsed to Dashboard>Sandbox>accounts, (find the facilitator and buyer accounts - which apperently do require decent passwords to work) than press "Click Me" just to fail again by being redirected to a page indicating:

"We're sorry. Relying party validation error: client_id or redirect_url provided in the request does not match any of the registered clients. Please check the request and try again."

Answer 1

OK, found a way aroudn this.

Problem: For some reason if you are a PayPal user and also wish to use the sandbox (in my case I have a seperate private account and a business account, and the sandbox is used by the busienss account), any attempt to approach the sandbox results in being redirected to paypal main site (at least in my region).

Solution: Use a seperate cognito or private window for the sandbox - never login to you your own account while working with the sandbox, and if you do, restart the browser and get a new private window.
