Your system can sell our inventory through two APIs: the OCTO API and Distribution API v2. Both sell the same products at the same rates and availability.
Use the OCTO API if you are starting fresh or already work with OCTO suppliers. Use Distribution API v2 if your system already speaks the v2 contract.
Press Reference on the OCTO card. Building a storefront walks through a booking in order.
Reserving holds the places and your funds; confirming captures the money and issues vouchers. An unconfirmed hold expires by itself.
Press the second Reference for Distribution v2. Its Booking section follows the same pattern.
Once your sandbox integration works, press New key, set Environment to Production and issue it. Swap it into your system; the address stays the same.
Careful. A production key books for real and pays from your real wallet. Keep it as safe as a password.
