Use a directory’s native webhook or event feed when it covers the changes you need to track. Verify incoming messages, make processing safe to retry, and reconcile state so missed events do not leave your records stale. If the directory has no suitable notifications, poll its API or directory on a deliberate schedule, retain normalized snapshots, and alert on meaningful differences.
Decide which changes matter
Start by listing the directory records your team relies on and the changes that should trigger action. Depending on the directory, these might include a new partner listing, a profile edit, a status change, a removal, a relationship change, or a change to integration capabilities.
Then check the provider’s event documentation for the actual event names, resource scope, and supported environments. A platform may notify about one resource type or lifecycle without covering every change visible in its directory. Do not treat another provider’s event list as a coverage guarantee.
Choose a monitoring method
| Approach | When it fits | What to verify |
|---|---|---|
| Provider webhook | The directory emits events for all the records and changes you need. | Event coverage, message authentication, delivery delay, retry behavior, and any offline queue or replay mechanism. |
| Cloud event routing | The provider exposes events through a cloud event service. | Required IAM permissions, routing rules, target health, and the retention or replay features enabled in your configuration. |
| Scheduled polling and comparison | No suitable event feed exists, or its coverage leaves gaps. | API access and limits, polling cadence, snapshot retention, normalization, false positives, and reconciliation effort. |
There is no universal best method or standard polling interval. Compare the options against your required coverage, acceptable detection delay, security controls, recovery needs, and operating effort.

Use native notifications where they fit
Provider documentation illustrates how much event models differ. Microsoft Partner Center documents HTTP POST resource-change webhooks, while AWS Partner Central documents account-connection lifecycle notifications routed through EventBridge. PartnerPage and eno.forum document their own directory or listing events. These are platform-specific examples, not interchangeable guarantees: Microsoft Partner Center webhook events, Microsoft Partner Center webhooks, AWS Partner Central account API documentation, PartnerPage Knowledgebase, and eno.forum developer documentation.
Microsoft describes webhooks as an alternative to constantly checking Partner Center APIs. However, the Partner Center guide also says its subscription-updated event can lag the underlying change by up to 48 hours. Treat that as a documented limit for that event, not as a general webhook delay.

Use polling to cover gaps
When events are unavailable or incomplete, read the directory or API on a schedule chosen for your detection needs and the provider’s access limits. Save each result as a normalized snapshot, then compare it with the prior snapshot. The interval is an engineering decision; the available platform documentation does not define a universal cadence.
Implement notifications safely
- Register the event destination. Follow the provider’s subscription process and select only the event types and resources you need. Confirm whether authorization is required and whether a test or sandbox event is available.
- Protect the callback. Expose only the endpoint required by the provider. Validate signatures or other documented authentication controls before accepting an event or taking action. Microsoft documents digitally signed Partner Center delivery and instructs recipients to validate that a message came from Microsoft.
- Record enough to diagnose delivery. Store the event ID, timestamp, resource identifier, and processing outcome when the schema provides them. Avoid relying on arrival order alone; use provider-documented identifiers and timestamps to reason about duplicates and delayed events.
- Make handlers safe to retry. A repeated notification should not cause duplicate downstream actions. Use an idempotency strategy appropriate to the event and keep failures visible for investigation.
- Monitor delivery and reconcile state. Track endpoint health and processing failures. Maintain a way to compare the provider’s current state with your own, particularly for events that may be delayed, exhausted after retries, or otherwise missed.
- Test registration and production delivery. Send the provider’s test event if supported, verify it reaches and passes validation at your endpoint, and then confirm that real events are processed and reflected in your system.
Plan for Microsoft Partner Center’s documented retry behavior
For Partner Center, Microsoft documents ten delivery attempts. If an event remains undelivered, it is moved to an offline queue and Microsoft makes no further delivery attempts. This behavior is specific to Partner Center. Monitor endpoint health and arrange reconciliation or follow-up for gaps rather than assuming the provider will retry indefinitely.

For AWS Partner Central account-connection notifications routed through EventBridge, check the required IAM permissions and verify the event rule and target configuration in the environment you use. A configured event source alone does not establish that the destination is authorized, healthy, or retaining events for recovery.
Build a reliable polling and diff process
- Fetch and normalize. Read the records available through the provider’s documented API or directory access method. Normalize identifiers, fields, and status values so formatting differences do not appear as meaningful edits.
- Persist a versioned snapshot. Keep the timestamp, source, and records for each successful read. Retention helps investigate alerts and distinguish real changes from ingestion problems.
- Compare by stable identity. Match records using provider identifiers where available. Classify additions, field edits, status changes, and removals separately.
- Apply alert rules. Notify only for changes that matter to the team. Ignore or suppress inconsequential field churn, and include the affected record and before-and-after values when appropriate.
- Handle incomplete reads cautiously. Do not interpret a failed or partial API response as mass removal. Mark the run as incomplete and preserve the last known good snapshot until a complete read can be compared.
- Reconcile after failures. After an outage or an event-processing gap, retrieve current state and compare it with your stored state to restore consistency.
Troubleshoot missed or noisy changes
- No events arrive: Confirm the subscription is registered for the correct resource and environment, the callback is reachable, and any required authorization or cloud permissions are in place. Use a documented test event to isolate registration and delivery from event coverage.
- Signature validation fails: Check that validation follows the provider’s documented signing procedure and uses the expected request data and key material. Do not disable validation as a shortcut.
- The alert arrives late: Check the provider’s stated timing for that specific event. Partner Center documents up to a 48-hour delay for its subscription-updated event; do not apply that figure to unrelated providers or events.
- Some changes never appear: Verify that the event type covers the resource and action in question. Add scheduled reconciliation or polling for uncovered changes rather than assuming a webhook is a complete audit stream.
- Repeated alerts or duplicate actions occur: Make processing idempotent, record event identifiers where available, and separate duplicate delivery from a genuinely new resource change.
- Polling reports mass removals: Check whether the read was complete and successful before interpreting absent records as deleted. Preserve the last good snapshot when a fetch fails or returns partial data.
- Too many low-value alerts fire: Normalize fields before comparison and tune alert rules to focus on relevant additions, edits, status changes, or removals.
