# Inbox

WeChat messages, the 48 hour reply window and the inbox webhooks.

Messages sent to your Official Account arrive in the inbox like any other channel. Replies go out as WeChat customer service messages.

## Direct messages

| Feature | Supported |
|---------|-----------|
| List conversations | <Yes /> |
| Fetch messages | <Yes /> |
| Receive text, images, voice, video | <Yes /> |
| Receive locations and links | <Yes /> |
| Receive custom menu clicks | <Yes /> |
| Send replies | <Yes /> (within the window below) |

The [Messages API](/messages/list-inbox-conversations) has every endpoint. Filter with `platform=wechat`.

## The 48 hour window

WeChat accepts customer service messages only within 48 hours of the customer's last message, and at most 5 of them in that window.

- A reply outside the window, or past the fifth, is rejected.
- The window opens again, with a fresh count, when the customer writes.
- There is no template or paid message type that reaches a customer outside the window through Zernio.

## Automations

Keyword replies and other automations run on WeChat conversations as on every channel, within the same window.

## Webhooks

| Event | When it fires |
|-------|---------------|
| `message.received` | A customer sends a message to the account |
| `message.sent` | An outgoing message is sent |
| `conversation.started` | A customer writes to the account for the first time |

The [webhooks page](/webhooks) has the payloads.
