Verified steps POST /v1.0/subscriptions with changeType, resource (e.g. me/mailFolders('Inbox')/messages), notificationUrl, expirationDateTime Echo back the validationToken (plain text, 200) on the initial validation request within 10s Process notifications; respond 202 quickly PATCH the subscription before expiry (mail max ~3 days, most resources ≤3 days) Known gotchas Subscription lifetimes are SHORT (mail ~4230 min max) — renewal automation is mandatory, not optional Validation request arrives with content-type text/plain and must be answered with the raw token, not JSON Notifications carry resource ids only, not content — you must call back into Graph for the data (or use rich notifications with encryption certs)
