Core concepts: Agents, Channels & Playbooks
Three primitives power every Helio deployment. Once you understand how they fit together, the rest of the product is just configuration on top of these ideas.
The three primitives
Helio is built on a small, deliberately limited vocabulary. Every campaign, automation, and analytics view in the product reduces to some combination of:
| Primitive | What it is | Example |
|---|---|---|
Agent | The brain. A trained model with personality, knowledge, and guardrails. | "Sales rep who knows the catalog and writes like a friend" |
Channel | The mouth. Where the agent shows up — WhatsApp, Instagram, email, on-site. | WhatsApp Business API, Instagram DM, email |
Playbook | The plan. A sequence of triggers, conditions, and messages. | "If cart abandoned > 30min, send WhatsApp; if no reply in 4h, send email" |
Agents
An Agent is what your customers actually interact with. Every Agent has:
- A persona — name, voice, tone, refusal style
- Knowledge — your product catalog, FAQs, policies, past chats
- Tools — actions it can take: look up an order, apply a discount, escalate to a human
- Guardrails — what it must never do (e.g. promise free shipping, discuss competitors)
Create an Agent
Most stores ship with two — a sales agent and a support agent. Here's how to create one:
POST https://api.helioai.tech/v1/agents
Authorization: Bearer hk_live_...
{
"name": "Catalog Concierge",
"type": "sales",
"persona": "warm, concise, never pushy",
"knowledge_sources": ["shopify:catalog", "notion:faqs"]
}Channels
A Channel is the surface your Agent speaks through. Each Channel has its own constraints — message length, media types, reply windows, opt-in rules. Helio handles these for you, but it's worth knowing the shape of each.
| Channel | Reply window | Media | Best for |
|---|---|---|---|
whatsapp | 24 hours | Images, video, docs, buttons | High-intent, post-purchase |
instagram | 24 hours | Images, video, stickers | Discovery, brand-led |
email | None | Rich HTML | Long-form, win-back |
website | Live | Anything | Pre-purchase Q&A |
Playbooks
If Agents and Channels are the actors and stages, Playbooks are the script. A Playbook describes a flow as a small graph of triggers, conditions, and actions.
