+Several key factors can prevent events from being successfully ingested into the Segment platform through server-side libraries as sources. Understanding these reasons is crucial for troubleshooting and ensuring data integrity. Here are some suggestions to address these challenges:
+
+If you are experiencing loss of events ingested from your {% page.title %}, 
+
+- **Payload is too large**: If you attempt to send events larger 32KB per normal API request or batches of events larger than 500KB per request, Segment’s tracking API responds with 400 Bad Request. Try sending smaller events (or smaller batches) to mitigate this error.
+
+- **Identifier is not present**: Segment's tracking API requires that each payload has a `userId` and/or `anonymousId`. If you send events without either the `userId` or `anonymousId`, Segment's tracking API responds with ERROR CODE ERROR NAME.
+
+- **Track event is missing name**: All Track events to Segment must have an event field.
+
+- **Event dropped during deduplication**: Segment automatically adds a `messageId` field to all payloads and uses this value to deduplicate events. If you're manually setting a `messageId` value, ensure that each event has a unique value to avoid data loss.
