Every identity verification provider has its own request format, authentication and error codes. A bank that wants PAN, bank account and bureau checks from different vendors ends up maintaining three integrations. An aggregation platform turns that into one.
Adapters, not if-statements
Each provider and check pair gets its own adapter with two jobs: map our common request into the provider’s payload, and map the provider’s response back into our common response. At start-up the adapters register by key, and the gateway looks up which one to call. Adding a provider means adding adapters, not editing the core.
What customers actually see
- One API key, with sandbox and live prefixes.
- One response format for every check.
- A wallet, prepaid or postpaid, debited per call at their own price.
- IP allow-lists, rate limits and a full request log.
The same architecture carries over to payments: one merchant integration in front, many rails behind.
