Handle webhooks
Local rails complete asynchronously. Verify the signature, treat a payment as paid only on a success webhook, and make your handler idempotent.
Webhook endpoints and deliveries
Set the endpoint TensorRail delivers webhooks to and rotate its signing secret in the dashboard; read the configuration and inspect or retry deliveries through the API.
Error intelligence
One canonical error catalog across every rail: a decline means the same thing whatever produced it, so you write error handling once.
Error catalog
Every ERR_NNNN code the API returns, grouped by family, with the meaning and the handling for each. code is the field to branch on.
Orchestration and routing
Rule-based routing across the rails enabled for your account, one outcome per payment, and safe client retries with Idempotency-Key.
