After this guide, each inbound message in a Front inbox reaches your agent, and the agent’s answer is posted back into the same Front conversation as a message from “Lua AI Assistant”. You need a Front workspace with permission to create an API token and a webhook. The channel is set up in the admin dashboard or with the admin REST API; there is no CLI command. Verified against lua-cli 3.33.0. Before you begin
  • A Front API token for the workspace. Lua validates it against Front’s /me endpoint when you save the channel.
  • A Front webhook signing key. Lua uses it to verify the X-Front-Signature header on every delivery.
  • Access to the agent in the admin dashboard, or an API key with the channels:manage scope on it.

Provider console: create the token and note the webhook key

In Front, create an API token for the workspace and find the signing key for webhooks . Keep both; Lua stores them with the channel and never returns them.

Dashboard: add the Front channel

Add a channel of type Front to the agent with the token as the workspace token and the signing key as the webhook key (POST /admin/agents/<agentId>/channels with type: "front" and a front object of workspaceToken and webhookKey). The response includes webhookUrl, of the form https://wa.heylua.ai/front/<channelId>. An invalid token fails with Invalid workspace token. Please check your Front API credentials and try again.

Provider console: send inbound messages to the webhook URL

In Front, create a webhook (or a rule whose action sends to a webhook) that targets the webhookUrl for new inbound messages in the inboxes the agent should handle . Lua processes deliveries whose type is inbound and ignores every other event.

Verify

Send an email or message to the inbox. Within the Front conversation, a reply appears from “Lua AI Assistant”; Lua.request.channel inside your tools is front. Confirm the turn with lua logs --type agent_response.

​
Channel behavior

The reply is posted with Front’s conversation messages API, leaves the conversation unarchived, and is recorded as a delivery with Front’s message id; Front sends no receipts. Because the end user is the conversation, memory and User data don’t carry across conversations with the same person.

Troubleshooting

Both values are mandatory when the channel is created. Paste the Front API token as the workspace token and the webhook signing key as the webhook key.
Lua couldn’t call Front’s /me endpoint to validate the token, or Front answered with an error other than 401 or 403. Retry; if it persists, check Front’s status page.
Deliveries whose signature doesn’t match the stored webhook key are rejected, and events other than inbound are ignored. Re-create the channel with the current signing key, and make sure the Front webhook fires on inbound messages.
