Architecting Asynchronous Video Message Workflows for Timezone-Displaced Customer Support

What This Guide Covers

This guide details the architectural pattern for implementing a bidirectional asynchronous video messaging loop in Genesys Cloud CX. You will configure an outbound video notification system that allows agents to send pre-recorded or live-captured video responses to customers outside business hours, and an inbound ingestion pipeline that routes customer video replies to specific agent queues for asynchronous review. The end result is a fully functional “Video Voicemail” workflow that integrates with the Genesys Media Store, handles large payload constraints, and provides agents with a unified interface for managing non-real-time visual interactions.

Prerequisites, Roles & Licensing

  • Licensing Tier: Genesys Cloud CX 3 (required for Advanced Architect features and full API access to Media Store).
  • Add-ons: Genesys Cloud Video Messaging (or equivalent custom integration if using third-party storage like AWS S3 with Genesys Web Messaging).
  • Permissions:
    • routing:queue:view and routing:queue:edit for queue configuration.
    • architect:flow:view and architect:flow:edit for flow design.
    • media:media:view and media:media:edit for media store management.
    • telephony:outbound:view for outbound campaign setup (if triggering via SMS/Email links).
  • OAuth Scopes: media:media:read, media:media:write, routing:queue:read, architect:flow:read.
  • External Dependencies: A compliant object storage provider (if offloading from Genesys Media Store for cost optimization) and a frontend video capture component (WebRTC or mobile SDK) for the customer-facing interface.

The Implementation Deep-Dive

1. Designing the Inbound Video Ingestion Pipeline

The core complexity of asynchronous video support lies in the ingestion of large binary files through standard web channels. Genesys Cloud is optimized for low-latency voice and text. Video files, even compressed, exceed standard message size limits and require asynchronous processing. We do not attempt to stream video through the standard Web Messaging WebSocket connection. Instead, we use a “Link-First” architecture.

The Architectural Pattern

The customer does not upload the video directly to the Genesys Web Messaging endpoint. The workflow follows this sequence:

  1. Customer initiates a chat session via Web Messaging.
  2. Genesys Architect flow detects the intent “send video”.
  3. The flow returns a pre-signed URL (PSU) or a link to a dedicated video capture portal.
  4. Customer records/uploads video to the external storage or Genesys Media Store.
  5. The completion callback triggers a webhook to Genesys Cloud.
  6. The webhook creates a new message in the existing conversation with a thumbnail and metadata.

Step 1:1: Configuring the Media Store for Video Assets

Genesys Cloud Media Store has strict size limits. For production-grade video messaging, you must configure your storage strategy carefully. If you stick with Genesys Media Store, ensure your files are under 50MB. For larger files, you must integrate AWS S3 or Azure Blob Storage.

The Trap: Do not store raw video files in the Genesys Conversation Transcript. The transcript is a JSON object. Embedding base64-encoded video data will corrupt the transcript, break reporting, and cause severe latency in the agent desktop. The transcript should only contain a text payload with a clickable URL and a metadata object containing the duration, format, and storage location.

Step 1:2: Building the Inbound Webhook Flow

Create a new Architect Flow named Video_Ingestion_Webhook. This flow listens for HTTP POST requests from your video capture service.

Endpoint Configuration:

  • Flow Type: Webhook
  • Method: POST
  • Content Type: application/json

The Payload Expectation:
Your external service sends a JSON body upon successful video upload.

{
  "conversationId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "mediaUrl": "https://s3.amazonaws.com/bucket/video_123.mp4",
  "thumbnailUrl": "https://s3.amazonaws.com/bucket/thumb_123.jpg",
  "duration": 45,
  "customerId": "ext_cust_9988",
  "mimeType": "video/mp4"
}

Flow Logic:

  1. Set Data: Parse the incoming JSON body. Store conversationId, mediaUrl, and thumbnailUrl in local variables.
  2. Get Conversation: Use the Get Conversation block with the conversationId variable. This ensures the message is appended to the correct existing thread.
  3. Add Message: Use the Add Message block.
    • Type: Text
    • From: Customer (or a specific Bot persona)
    • Content: Construct a rich text or markdown message.

The Message Payload Construction:
Do not send raw HTML. Use Genesys’ supported rich text format or a simple markdown link that the agent desktop can render.

{
  "type": "text",
  "content": "**Video Message Received**\n\n[View Video]({{mediaUrl}})\n\n*Duration: {{duration}}s | Format: {{mimeType}}*"
}
  1. Update Conversation Metadata: Use the Update Conversation block to append a custom attribute hasVideoAttachment: true. This allows for downstream reporting and queue routing rules.

Architectural Reasoning:
By decoupling the storage from the messaging layer, we avoid blocking the Web Messaging WebSocket with large payloads. The agent sees a lightweight text message immediately. When they click the link, the video streams from the high-throughput storage provider, not through the Genesys messaging relay. This preserves the responsiveness of the agent desktop.

1.3: Queue Routing for Asynchronous Review

Video messages require different handling than text. An agent cannot “listen” to a video message while typing a response. We must route these to a queue with specific settings.

Queue Configuration:

  1. Create a new Queue: Async_Video_Review.
  2. Enabled: Yes.
  3. Wrap-Up Time: Set to 120 seconds. Video review requires more context switching time.
  4. Overflow Settings: Disable standard overflow. Video messages are non-urgent by definition. Use Long Wait Handling to defer rather than abandon.

The Trap: Do not use standard Service Level targets for video queues. Setting a 20-second SLA on a video message queue is architecturally unsound. Video messages are inherently asynchronous. If you enforce a strict SLA, agents will be penalized for taking time to watch a 2-minute video. Instead, configure the queue to use Manual Acceptance or Presence-Based Routing where agents pull work when they have bandwidth, rather than being pushed work based on wait time.

2. Architecting the Outbound Video Notification System

The outbound flow allows agents to send video responses to customers who are offline or in different timezones. This requires generating a secure, expiring link to a video asset and delivering it via a preferred channel (Email, SMS, or Web Message).

Step 2:1: Agent-Initiated Video Capture

Agents record videos within the Genesys Cloud Agent Desktop or a custom embedded widget. The video is uploaded to the Media Store or external storage.

API Integration for Upload:
If building a custom agent widget, use the Genesys Cloud Media API to upload the file.

POST /api/v2/media/media
Authorization: Bearer <access_token>
Content-Type: multipart/form-data

file=@video.mp4
type=video

Response:
The API returns a mediaId and a downloadUrl.

Step 2:2: The Outbound Notification Flow

Create an Architect Flow named Outbound_Video_Notification. This flow is triggered by a custom event or a button click in the Agent Desktop via the Send Event API.

Trigger:

  • Event Type: Custom
  • Event Name: agent.video.send

Payload from Agent Desktop:

{
  "targetChannel": "email",
  "targetAddress": "customer@example.com",
  "mediaId": "media_12345",
  "subject": "Your Video Response",
  "body": "Please review your video response from Agent John."
}

Flow Logic:

  1. Set Data: Parse the event payload.
  2. Get Media: Use Get Media with mediaId. Retrieve the downloadUrl.
  3. Check Expiry: Verify the media URL is not expired. If it is, trigger a re-upload or error path.
  4. Send Email/SMS:
    • Use the Send Email block.
    • To: {{targetAddress}}
    • Subject: {{subject}}
    • Body: Insert the downloadUrl into a branded HTML template.

The Trap: Never embed the direct downloadUrl from Genesys Media Store in an unauthenticated email if the content is PII (Personally Identifiable Information). Genesys Media Store URLs can sometimes be guessed or shared. For HIPAA/PCI environments, you must generate a Pre-Signed URL with a short TTL (Time-To-Live, e.g., 1 hour) from your external storage provider. The flow should call an external webhook to generate this secure, expiring link before sending the email.

Step 2:3: Tracking Engagement

How do you know if the customer watched the video? Standard email opens are insufficient.

Architectural Solution:
Host the video on a server that logs access. When the customer clicks the link, log the timestamp and IP address. Send this data back to Genesys Cloud via a webhook to update the conversation metadata.

Webhook Payload:

{
  "conversationId": "conv_123",
  "videoId": "vid_456",
  "status": "viewed",
  "viewTimestamp": "2023-10-27T10:00:00Z"
}

Flow Update:
An inbound webhook flow catches this and updates the conversation attribute videoViewed: true. This allows the agent to see a “Viewed” badge in their desktop, indicating the customer has engaged with the content.

3. Frontend Integration for Customer Video Capture

The customer-facing side requires a robust video capture component. You cannot rely on standard <input type="file"> for mobile users. You need a WebRTC-based capture interface.

Recommended Tech Stack

  • Library: RecordRTC or MediaRecorder API for browser-based capture.
  • Compression: Transcode video to H.264/MP4 on the client side if possible, or upload raw and transcode on the server. Client-side compression reduces bandwidth costs.
  • Upload: Chunked upload to S3/Azure Blob. Do not upload to Genesys Cloud directly from the customer browser due to CORS and size limits.

The Trap: Mobile Safari has strict autoplay and data-saver policies. Ensure your video player on the customer side uses playsinline and provides a clear call-to-action button. If the video fails to load, the customer will abandon the interaction. Always provide a fallback text summary in the email/SMS notification.

Validation, Edge Cases & Troubleshooting

Edge Case 1: Large File Upload Failures on Mobile Networks

The Failure Condition: Customers attempt to upload video from 4G/5G networks. The upload fails midway, and the webhook is never triggered. The agent sees no message, and the customer is confused.
The Root Cause: Unstable network connections interrupt the multipart upload. Genesys Cloud has no visibility into the upload progress.
The Solution: Implement client-side retry logic with exponential backoff. Use a library like tus.js for resumable uploads. The frontend must display a “Uploading…” state and only transition to “Sent” upon receiving the 200 OK from the storage provider. Additionally, send a confirmation SMS to the customer upon successful upload to close the loop.

Edge Case 2: Media Store URL Expiration

The Failure Condition: An agent sends a video link via email. The customer clicks it 3 days later, and gets a 404 or 403 Forbidden error.
The Root Cause: Genesys Media Store temporary URLs expire after a short period (default is often 24 hours). External S3 pre-signed URLs also expire.
The Solution: For outbound links, always use a “Link Resolver” pattern. Do not send the direct media URL. Send a link to a lightweight serverless function (e.g., AWS Lambda) that checks if the media exists and generates a fresh pre-signed URL on the fly. This ensures the link never expires as long as the media file exists in storage.

Edge Case 3: Agent Desktop Rendering Issues

The Failure Condition: The agent receives the text message with the video link, but the Genesys Agent Desktop does not render the thumbnail or the link is not clickable.
The Root Cause: The Add Message block used an unsupported HTML tag or the markdown parser in the specific desktop version (Web vs. Desktop App) handles links differently.
The Solution: Stick to plain markdown [Label](URL) or simple HTML <a href="URL">Label</a>. Avoid complex HTML structures. Test the message rendering in both the Genesys Web App and the native Desktop App. If thumbnails are required, use the Genesys Image message type, but ensure the image URL is publicly accessible and CORS-enabled.

Edge Case 4: Compliance and Retention

The Failure Condition: A video message containing PII is retained indefinitely, violating GDPR or HIPAA retention policies.
The Root Cause: Genesys Cloud conversation transcripts retain the text link, but the media file in external storage persists separately.
The Solution: Implement a lifecycle policy on your external storage bucket (e.g., S3 Lifecycle Rules) to delete objects after 30 days. Additionally, configure Genesys Cloud Conversation Retention Policies to archive or delete the conversation transcript after the required period. Ensure the webhook that creates the message includes a retentionExpires attribute if using Genesys’ native retention features.
