## How Connection Works

Indic8 works using two simple methods:

1. **Real-Time Webhooks**: Every time a customer buys or renews, your payment provider sends a quick notification to Indic8. Indic8 checks the security signature and updates your numbers in under 2 seconds.
2. **Read-Only API Keys (Optional)**: If you want to import older sales from past months, you can add a read-only key. Indic8 never asks for write permissions.

***

## Security Promise

<Check>
  **Zero Write Access**: Indic8 only reads transaction numbers and dates. It can never charge customers, create refunds, or change your products.
</Check>

<Check>
  **Zero Credit Card Storage**: Raw card numbers and sensitive customer details never touch Indic8 database disks.
</Check>
