What gRPC actually is (three technologies in a trench coat), the honest performance paragraph, where each protocol is simply correct, and the hybrid edge-REST/interior-gRPC topology mature systems converge on.
From both sides of hundreds of integrations: honest status codes, RFC 7807 errors with trace IDs, cursor pagination, idempotency and versioning posture, and the DX multipliers that halve support tickets.
The ladder from additive changes to real versions: tolerance rules that make 90% of changes free, deprecated-field telemetry, Sunset headers, brown-outs, and the internal-API discount.
Both sides of the wire: HMAC signatures with timestamps and constant-time compares, the raw-body trap, dedupe-and-queue consumers, producer retry etiquette and the checklist that prevents 3 a.m. replays.
e-Fatura vs e-Arşiv, SOAP clients that behave in modern .NET, UBL-TR mapping without tears, the status lifecycle, cancellation rules and a go-live checklist from real ERP integrations.
Germany now requires declaring every electronic cash register to the tax office. How to automate the whole pipeline — taxpayer, establishments, clients, XML validation and ERiC transmission — with the SUBMIT DE API.
A backend developer's walkthrough of Germany's cloud TSE: TSS lifecycle automation, client registration per BSI TR-03153, transaction signing with offline queueing, and audit-ready TAR exports.
