  "account": "Receiving webhooks from TikTok Shop Customer Service is straightforward, but constructing a production-grade pipeline that can handle duplicate deliveries, delayed events, missing messages, invalid signatures, and changing seller authorizations is a complex engineering task. This guide outlines the steps to build a robust pipeline, starting from HTTPS ingress to history reconciliation.\n\nBegin by understanding the scope of the TikTok Shop Customer Service API, which is specifically for conversations between buyers and sellers within a TikTok Shop. Ensure that your application has access to the necessary Customer Service API scopes, that the seller has authorized your application, and that the target shop is correctly mapped to your internal workspace or tenant. Remember that webhook access is initially inactive and requires approval.\n\nThe recommended architecture separates webhook acknowledgement from business processing. After receiving the webhook, verify the signature using the raw request body, then insert the event into a durable inbox before returning an HTTP 200 response within three seconds. After acknowledgment, persist the event and process it asynchronously using a message queue. Normalize, deduplicate, and route the messages before forwarding them to the customer service workspace. A separate worker handles history reconciliation.\n\nSubscribe to the NEW_MESSAGE event, identified by event type 14, which is triggered for incoming customer service messages. This subscription can be configured in the TikTok Shop Partner Center or through the webhook configuration API. The key fields to preserve from the webhook payload include tts_notification_id, shop_id, message_id, conversation_id, index, create_time, type, and visibility. These identifiers are crucial for deduplication, routing, ordering, and investigating incidents.\n\nBefore parsing the payload, verify the signature sent in the Authorization header using HMAC-SHA256. The signature is generated by combining the app_key with the raw webhook body, using the application's app_secret as the signing key. It's essential to verify the raw body directly, without parsing or serializing the JSON first, to avoid signature validation issues caused by whitespace changes or character encoding. A Node.js example of signature verification is provided, using constant-time comparison to prevent timing attacks and never logging the app_secret.\n\nOnce the webhook request has been securely processed, the event can be handled in your internal message model. This architecture ensures that your system remains resilient to various webhook delivery challenges while maintaining the necessary data for effective customer service management within TikTok Shop.",
