Why it crawls your site
The bot does not crawl for indexing or data scraping purposes; instead, it performs a specific POST request to a pre-configured URL provided by the merchant during integration. This request contains the transaction details, allowing the merchant's system to verify the payment status against SimPay's records. Website administrators can verify this bot by checking that incoming requests originate from SimPay's official IP ranges and contain the expected cryptographic signatures.
