Hello everyone! we are so excited to roll out the LINE messaging integration in Genesys Cloud! The messages are routing perfectly to our 800 agents. However, we have a major issue with Data Actions. When a customer messages us on LINE, the interaction details only show a generic alphanumeric LINE user ID. We use a Data Action in our Architect inbound message flow to query our internal CRM using this LINE ID to pull the customer’s real name and loyalty tier. Unfortunately, the Data Action keeps failing because the LINE ID provided by the Genesys Cloud built-in variable (Message.Message.senderAddress) is not the actual persistent LINE user ID our CRM expects. How do we extract the true, persistent LINE provider ID in Architect to pass to our Data Action?
This is incredibly frustrating and poorly documented! I maintain dozens of flows and had to build a workaround for this exact issue. The Message.Message.senderAddress variable in Architect does NOT contain the persistent provider ID for third-party messaging apps like LINE or WhatsApp. It contains an ephemeral Genesys Cloud participant address. To get the true provider ID (the one your CRM actually knows), you must use the Get External Contact action in your flow, searching by the conversation ID, or you must invoke a separate Data Action that queries the /api/v2/conversations/messages/{conversationId} endpoint to parse the raw JSON payload and extract the externalContactId from the participant list. It is a ridiculous extra step.
I look at raw payload data frequently. To expand on 's point, the reason Genesys Cloud abstracts the address in the standard variable is to normalize the Architect flow experience across all digital channels (Web Chat, SMS, LINE, etc.). If you query the conversation details via the API as suggested, look specifically in the participant array for the user with the purpose of customer. Inside their messaging array, you will find the to and from fields which contain the raw, native LINE user ID you need for your CRM lookup.
