I need clear, beginner-friendly, step-by-step instructions that walk me through connecting PayPal to my Bókun account via Braintree. At the moment I only have sandbox access in the Braintree control panel, yet Bókun is asking for a Live Access Token generated through the Braintree SDK. Here’s what I’m hoping to receive: • A concise explanation of the difference between sandbox and live credentials—and what has to happen in my Braintree dashboard before a live token becomes available. • The exact navigation path in Braintree to locate or generate that Live Access Token, including any prerequisite account verifications or merchant‐ID approvals. • Screen-by-screen guidance on where to paste each credential inside Bókun so PayPal payments can be processed without errors. • Any common pitfalls a first-time integrator should watch for (e.g., webhooks, currency or locale settings, PayPal “Enabled” toggle inside Braintree). Please keep the language simple and assume no prior experience with payment-gateway integrations. Code snippets are welcome if they help illustrate where tokens go, but my main need is a written walkthrough that I can follow from start to finish until I see “Connected” in Bókun.
