There is no separate sandbox host and no test path prefix -- the same base URL (https://app.lendapi.com/api/v1/) serves both modes. key_prefixes: not published base_url: https://app.lendapi.com/api/v1/ mode_signal: field: live_mode location: webhook event envelope values: [true, false] evidence: >- The published example webhook payload carries "live_mode": false, so consumers can tell test traffic from live traffic on the event side. source: https://developer.lendapi.com/reference/example-response test_values: published: false notes: >- LendAPI publishes NO magic test values -- no test SSNs, no test applicant identities, no test bank accounts or cards, and no documented triggers for forcing an approve / decline / manual-review outcome from the decision engine. Test-mode behaviour is driven entirely by the tenant's own configured products, decision trees and pricing engines rather than by fixed fixtures. Nothing is invented here. test_clock: supported: not documented fixtures: tooling: none published self_service: signup_url: https://app.lendapi.com/login/ notes: >- Access is commercial -- the pricing page routes to "Contact Us" for both the LOS and Embarc LMS products, so test credentials are provisioned through sales rather than by open self-service signup.
