Platform Status & Microsoft CSP Updates
Breaking changes countdown, active promotions, and your readiness checklist — updated continuously.
Breaking changes & deadlines
Microsoft CSP program changes that require action. Tagydes platform status shown for each.
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.
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.
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.
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.
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.
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.
Your readiness checklist
Everything you need to action before the March and April deadlines. Tagydes handles most of this automatically.
Verify your reconciliation integration uses v2 API — 12 days
Any integration calling GET /v1/invoices/unbilled/lineitems will break on March 15. If you use Tagydes, you're already on v2. If you have custom integrations or third-party tools, verify them now.
Review open EST decisions for eligible subscriptions — 29 days
Check subscriptions eligible for Extended Subscription Terms in your Tagydes dashboard. Opt in or opt out before April 1 to avoid automatic term changes. Navigate to Subscriptions → filter by "EST eligible".
Confirm your Partner Center credentials use SAM with MFA — 29 days
Your Microsoft Partner Center connection in Tagydes should be configured via the Secure Application Model with a refresh token obtained after MFA. Check Settings → Microsoft Connection → verify the MFA validation shows green. Go to settings →
MCA attestation enabled for new customers
Tagydes automatically records Microsoft Customer Agreement acceptance during customer onboarding. No action needed — new customers created through Tagydes are automatically compliant with the February 2 enforcement.
Azure price list ingestion updated to new CSV format
Tagydes updated price list parsing to the new Microsoft CSV format that went live on March 1, 2026. Your pricing data is accurate.
GDAP relationships configured for admin access
Granular Delegated Admin Privileges are required for all new customer admin relationships. Legacy DAP is being phased out. Configure GDAP relationships in Settings → Customers → GDAP.
Promotion eligibility scanning active
Tagydes scans eligible Microsoft promotions for your customers automatically. Check the Active Promotions section below to see what's available and when it expires — then apply from within the platform.
Active Microsoft promotions
Current promotions your customers may be eligible for. Applied automatically through Tagydes.
35% discount on new Microsoft 365 Copilot seat additions for existing Microsoft 365 Business Standard/Premium subscribers. New seats only — applies for 12 months from activation.
20% off Microsoft Teams Phone with Calling Plan for new activations. Eligible for customers migrating from legacy PBX or third-party calling solutions. Minimum 5 seats.
15% discount on Azure Consumption for new Azure customers in their first year. Eligible for CSP customers who have not had an Azure subscription in the last 12 months. Requires Azure plan activation.

Note: Promotion availability and eligibility depend on the customer's region, existing licenses, and specific Microsoft promotion terms. Tagydes scans eligibility automatically — promotions visible here are those for which at least one of your customers may qualify. Always verify final eligibility in your Partner Center sandbox before applying to live subscriptions.
