# Sendblue

Channel integration for eve. Send and receive iMessage, SMS, and RCS through Sendblue.

## Install

Add this Chat SDK channel from eve's registry. This writes `agent/channels/sendblue.ts` and installs Chat SDK and its adapter dependencies:

```bash
eve add channel/chat-sdk-sendblue
```

## Quick start

Create `agent/channels/sendblue.ts`:

```ts
// agent/channels/sendblue.ts
import { createSendblueAdapter } from "chat-adapter-sendblue";
import { createMemoryState } from "@chat-adapter/state-memory";
import type { Message, Thread } from "chat";
import { chatSdkChannel } from "eve/channels/chat-sdk";

export const { bot, channel, send } = chatSdkChannel({
  userName: "My Agent",
  adapters: {
    sendblue: createSendblueAdapter(),
  },
  state: createMemoryState(),
});

bot.onNewMention(async (thread: Thread, message: Message) => {
  await thread.subscribe();
  await send(message.text, { thread });
});

bot.onSubscribedMessage(async (thread: Thread, message: Message) => {
  await send(message.text, { thread });
});

export default channel;
```

See the [Sendblue adapter documentation](https://chat-sdk.dev/adapters/vendor-official/sendblue) for supported events, capabilities, and credentials.

## Configure

Set `SENDBLUE_API_KEY`, `SENDBLUE_API_SECRET`, and `SENDBLUE_FROM_NUMBER`, then point Sendblue webhooks at `/eve/v1/sendblue`. The adapter also supports tapbacks, typing indicators, delivery callbacks, and number lookup. See the [Chat SDK channel docs](/docs/channels/chat-sdk) for eve session dispatch, state, streaming, and human-in-the-loop behavior.
