Hi SendBird,

The List messages API docs are missing a spec on where the message\_ts and message\_id required parameters should be placed!

> **[Messages | Chat Platform API | Sendbird Docs](https://sendbird.com/docs/chat/v3/platform-api/guides/messages#2-list-messages)**
>
> Learn about the three types of messages: text, file or admin messages.

This is a blocker for the work I am doing!

Best,  
Simon

Hi @simonb,

The documents show that they’re a required parameter. So they should be placed as a query parameter:

An example of your URL, would be:

```auto
https://api-{APP_ID}.sendbird.com/v3/group_channels/{CHANNEL_URL}/messages?message_ts=1635082272

```
