Request for Slack api WebhookResponse send(String url, Payload payload) to return ts value about java-slack-sdk HOT 2 OPEN

Hi, @rhibiscusc! Thank you for your question! 🙌

Based on the documentation, it looks like not returning the ts is not just a limitation of the Java SDK, but a limitation of Incoming Webhooks in general:

You can use an Incoming Webhook to make your message appear as a reply in a thread. You'll need to retrieve the message ts value, however, as it is not returned when sending a request to an Incoming Webhook.

You can retrieve the ts value in one of the following ways:

• Enable and use the Events API so that you can subscribe to event types that will send a callback when a new message is sent by your webhook.
• Use the search.messages method to search for the message you sent based on the timestamp.
• Use the conversations.history method to search for the message from a set of messages.

I hope this helps!
