Settings decide which fiscal actions Lambda may perform and where it may send the result. Lambda checks required settings at the action boundary. A missing setting stops that action and records why.

​
Fiscal routes

All routes are enabled by default. When a route is disabled, Lambda does not perform that action. It records a configuration finding that names the skipped route. Full-value credits have one controlled alternative. If parent cancellation is disabled, Lambda can use the Tipo E route when it is enabled and the parent evidence is usable. Lambda does not switch to an unrelated route.

​
Provider environment

Test and live stamping use separate Facturapi organization bindings and certificate readiness. An invoice keeps the environment selected at capture. Lambda does not move an in-flight document from test to live or from live to test.

​
REP eligibility window

The REP eligibility window has:
  • Enabled
  • Window (days) from 0 through 365
It is disabled by default. When enabled, it can treat a parent as PUE for the configured calendar-day window after its CargoWise PostDate. Lambda snapshots the decision with the payment intent. A later setting change does not rewrite an existing REP. See Payments for the exact cutoff rule.

​
Invoice PDF design

The default is Detailed. Detailed resolves to Minimal when Lambda cannot prove that the exact logo is synchronized to the bound Facturapi organization. This fallback does not block issuance. The requested design, resolved design, logo version, and fallback reason are frozen on the stamp attempt.

​
CargoWise delivery

Lambda outbound needs a configured CargoWise inbound target and usable credentials. File allocation also uses:
  • CFDI XML document type
  • Cancellation XML document type
  • CFDI PDF document type
  • Payment complement document type
When the cancellation XML document type is empty, Lambda uses the normal CFDI XML document type. A missing delivery setting can stop delivery after the CFDI already exists. It does not undo the fiscal result.

​
Change timing

Route and provider settings are checked before the external action. PDF design, REP eligibility, and source identity are snapshotted where a later change could alter an in-flight decision. Settings changes affect future decisions unless the workspace explicitly shows a new attempt.
