Microsoft CSP program changes that require action. Tagydes platform status shown for each.

🚨 Critical Reconciliation March 15, 2026

Unbilled Reconciliation API v1 — Retired

Microsoft's synchronous GET /v1/invoices/unbilled/lineitems endpoint is being permanently retired on March 15, 2026. Any platform still calling v1 will start receiving errors. The new v2 async API delivers results in ~15 minutes instead of 15+ hours.

✓ Tagydes: Already running async v2 API — no action required from you

⚠️ Action required API Security April 1, 2026

MFA enforcement for Partner Center App+User API

Starting April 1, 2026, Microsoft will block App+User API calls that don't include a valid MFA claim in the token. Integrations using Secure Application Model without MFA in the token chain will fail. Tagydes validates the ms-mfa-validation header on every API call.

✓ Tagydes: MFA validation enforced — your connection will be checked on login

⚠️ Action required Subscriptions April 1, 2026

Extended Subscription Term (EST) grace period removal

Microsoft is removing the grace period for Extended Subscription Terms on April 1, 2026. Partners who have not opted in or out of EST for eligible subscriptions must do so before this date to avoid unexpected term commitments. Tagydes provides EST opt-in/out controls per subscription.

✓ Tagydes: EST opt-in/out API integrated — review subscriptions in the dashboard
29
days remaining
✓ Enforced since Feb 2 Compliance

MCA attestation required for all new customer orders

Since February 2, 2026, Microsoft blocks new orders for customers who haven't accepted the Microsoft Customer Agreement. Attempting to place an order without attestation returns error 600046. Tagydes records MCA attestation automatically during customer onboarding.

✓ Tagydes: MCA attestation handled automatically at customer creation
Done
enforced
✓ Done since Mar 1 Pricing

Azure price list migrated to new CSV format

Microsoft migrated the Azure price list to a new CSV format on March 1, 2026. Old parsers expecting the legacy format may produce incorrect pricing. Tagydes updated price list ingestion to the new format.

✓ Tagydes: Price list ingestion updated to new CSV format
Done
migrated
✓ Done since Oct 7 Compliance

Old MCA attestation API retired (October 7, 2025)

Microsoft retired the legacy attestation API on October 7, 2025. The enhanced API requires the Entra Object ID of the user who accepted the agreement — a real user from the customer tenant, not a service account. Tagydes uses the enhanced API exclusively.

✓ Tagydes: Using enhanced attestation API since October 2025
Done
retired
