Plan:

• in some cases it's possible to handle payments completely on-chain, i.e. send some message that proves the transfer
• payment processing stands for checking payments off-chain: monitor changes of the blockchain, see what things got finalized
• finalization takes time: 1 masterchain block TON transactions are irreversible after just one confirmation
• typical things to monitor: toncoins, jettons
• three options
  • write yourself
  • self-host API of a payment processor (for example, https://github.com/gobicycle/bicycle)
  • use third-party payment processor
