# Create your first agent

> From zero to a WhatsApp agent replying

## Before you start

<Check>A **connected WhatsApp Business number**. See [Connect your account](/en/channels/whatsapp/connect).</Check>
<Check>**WhatsApp** write permissions.</Check>

<Note>
  **Default roles don't include WhatsApp access.** Only Admin and Super Admin have it. If
  someone on your team can't see the WhatsApp section in the menu, they need a custom role.
</Note>

## Steps

<Steps>
  <Step title="Open the editor" icon="plus">
    **Chat → WhatsApp → Agents**, then press **Create agent**. You land straight in the editor.
  </Step>

  <Step title="Name and description" icon="pen">
    In the top bar. Only your team sees the description.
  </Step>

  <Step title="AI model and language" icon="microchip">
    First settings group, **AI Model & Responses**. It's the only one that starts open.

    * **LLM Model** — determines cost per message and answer quality.
    * **Response language** — `EN`, `ES` or `Multi`. Forces the reply language **regardless** of
      what the customer writes in.
    * **Temperature** — lower is more predictable. Some models fix it and the control appears
      locked.

    <Info>
      **📷 Screenshot needed** — the AI Model & Responses group expanded.

  </Step>

  <Step title="Channel: number, type and routing" icon="whatsapp">
    **WhatsApp Channel** group:

    * **WhatsApp phone number** — required.
    * **Agent Type** — Omnichannel, Inbound or Outbound.
    * **Routing** — required for inbound and omnichannel. Either tick **Default**, or set a
      weekly schedule.

    <Warning>
      There can only be **one default agent per number**. If one already exists, Dialtu asks you
      to give it a time range before taking its place.
    </Warning>

  <Step title="Write the prompt" icon="pen-to-square">
    The centre column. It's the only required content field.

  </Step>

  <Step title="Check the Summary and save" icon="circle-check">
    The **Summary** tab lists what's missing under **Required to create**: name, prompt, number
    and routing.

    Press **Create Agent**. It goes **live immediately**.
  </Step>
</Steps>

## Check that it works

Message the number from your phone over WhatsApp. You should see a reply within seconds and
the conversation under **CRM → Conversations**.

If it doesn't reply, check the agent is **Active**, that routing covers the current time, and
that the customer isn't excluded by audience filters.
