What is Grid and who is it for?

• Businesses sending international payouts
• Platforms enabling P2P payments
• Companies offering crypto on/off-ramps
• Businesses distributing rewards or incentives

2. Generate Sandbox API Keys

   Generate your sandbox API keys from the dashboard and start building and testing your integration.

Do I need to know about cryptocurrency to use Grid?

You interact with a simple REST API using familiar concepts like customers, accounts, and transactions. Bitcoin and stablecoins are just another payment rail that Grid manages for you automatically.
