Lerian SPI API contract changes
Lerian SPI 1.0.0, released on September 29, 2026, changed the idempotency header toX-Idempotency, moved the received Pix list and person statistics to POST, removed the Core MED case routes, and moved the direct participant to its own route.Lender
Lender API and event contract
What changedThe Lender reference publishes 122 operations instead of 52, including the whole assignment-of-receivables family, returned-payment receivables, version promotion, document templates and the accrual-run retry. The event catalog holds 37 definitions with three new ones; the dormant Consignado margin and proposal events are retired. The documented idempotency contract now covers 27 operations and is fail-closed, not fail-open.Who is affectedTeams integrating with the Lender API, consuming its events, or relying on the previously documented idempotency behaviour.What you need to doReview idempotency handling against the corrected fail-closed contract, sendX-Idempotency under that exact spelling, and drop subscriptions to the retired Consignado events.Lender
Lender guides updated for scheduled jobs and new refusals
Accrual closes a calendar month rather than a loan anniversary, two background jobs ship enabled, loan-application writes require an idempotency key, and origination refuses a product that is not active.DocumentationAPI Reference
Page URLs now mirror the navigation
Page URLs now mirror the navigation. Every page and API operation on docs.lerian.studio moved to the path its navigation position names:/en/<tab>/<anchor>/<page>, so a product page now sits under /en/products/<product>/. The old URLs are not redirected. Update saved links, product-console links, and any URL embedded in an API description or error payload.MidazTracer
Midaz v4 API and deployment model
Ledger/v2 is the current Core, CRM, and Fees API; CRM and Fees deploy with Midaz, while Tracer remains separately deployed.Streaming Hub
Streaming Hub multi-tenant configuration
Multi-tenant deployments use Tenant Manager, Redis, and deployment-level Kafka credentials; Secrets Manager remains for producer-manifest credentials.SISBAJUD
SISBAJUD KMS and credential configuration
SISBAJUD now documents the supported KMS selection path and sealed per-institution credentials.Consignado

Tracer CORS and service-discovery configuration
Empty CORS origins block cross-origin requests, and enabled service discovery requires an advertised address with a static fallback.SLC
