sk_test_ prefix.
Authentication And Access
Send the Sandbox API key as a Bearer token on every request.Simulated Operations
Simulated business responses include
mode: "test" and simulated: true. The auth-check response identifies the API key mode as test instead.
Identifier Formats
Sandbox Mode uses public identifiers only.- Generated request IDs use
REQ-and six digits, such asREQ-004219. - Generated service numbers are nine-digit numbers.
- The request management path accepts
REQ-followed by digits. Matching is not case-sensitive. The response uses uppercaseREQ-and pads the number to at least six digits. - Service paths accept a numeric service number.
Test Scenarios
Use the optionalX-Test-Scenario header to test selected response paths. Header values are not case-sensitive. An unknown value uses the success scenario.
The endpoint validates its path, query, and body input before it applies a test scenario. A malformed request can therefore return a normal validation error instead of the selected scenario. A denial in the request management endpoint also uses the denial response before it applies
nycservers_review.
Limitations
Sandbox Mode tests request structure, authentication, permissions, filters, and response handling. It does not test these live behaviors:- Record ownership, record existence, or the current service state.
- Provisioning, upstream password changes, plan changes, and cancellations.
- Email delivery, report generation, or report attachments.
- Persistent state or workflows that use an identifier from an earlier response.
- Live data volumes. List endpoints return at most one generated row, and report totals are fixed.
