The API Gateway Perjured Itself in Three Schema Versions
Incident Narrative
A TinyCTO.tv WHAT IF parable about breaking API changes, contract versioning, consumer compatibility. Version contracts explicitly, test consumers, support overlap, and remove old fields only after measured migration.
โThe API told the truth, the whole truth, and three mutually exclusive truths.โ
๐ฌArchitectural Diagnosis & Root Cause Analysis
Payments read null totals, reporting doubled revenue, and mobile treated every order as pending.
A breaking field rename shipped without version negotiation, compatibility tests, or a migration window.
Version contracts explicitly, test consumers, support overlap, and remove old fields only after measured migration.
โPERJURY: one endpoint delivered three incompatible truthsโ
๐Parable Script (17 Scenes)
Status: Verified Production DraftWe renamed totalAmount to total. Cleaner contract, zero drama!
๐ฌ Visual: The PM unveils one polished API contract under the evidence lamp.
Which version is under oath?
๐ฌ Visual: Glitch splits the contract into three flickering copies.
Payments still reads totalAmount.
๐ฌ Visual: The DBA places a payment consumer exhibit beside the new payload.
Mobile reads amount_total. Who taught it that?
๐ฌ Visual: Tiny CTO discovers a third field name hidden in a mobile briefcase.
The migration guide was in the meeting chat.
๐ฌ Visual: The PM projects an expired chat attachment marked as documentation.
Reporting mapped both fields. Revenue has achieved duplication.
๐ฌ Visual: Glitch watches one invoice become two revenue bars.
One producer, three consumers, no negotiated version.
๐ฌ Visual: The DBA aligns four incompatible contract exhibits.
Orders are pending, paid, and twice as profitable.
๐ฌ Visual: Three contradictory status lights illuminate one order box.
Dashboard calls that omnichannel consistency.
๐ฌ Visual: The PM points to a green consistency tile fed by contradictory data.
The payload changed at midnight. The app updates next Tuesday.
๐ฌ Visual: Glitch places the deployment clock beside a distant app-release calendar.
So compatibility was scheduled after incompatibility?
๐ฌ Visual: Tiny CTO draws the reversed migration timeline on the evidence board.
Contract test exhibit: absent. Deprecation window: also absent.
๐ฌ Visual: The DBA opens two empty evidence folders.
Root cause found: a rename with production privileges.
๐ฌ Visual: Glitch stamps BREAKING CHANGE across the response schema.
Could we call three truths resilient interpretation?
๐ฌ Visual: The PM rehearses the euphemism before the jury light wall.
Refunds are firing while reporting sends a congratulations email!
๐ฌ Visual: Refund slips rain beside a celebratory revenue banner.
Perjury. Restore overlap, test every consumer, then retire the old field.
๐ฌ Visual: The DBA orders an overlap window on the migration timeline.
The API told the truth, the whole truth, and three mutually exclusive truths.
๐ฌ Visual: Tiny CTO faces camera as three contracts swear on the same specification.
