Request for Slack api WebhookResponse send(String url, Payload payload) to return ts value

[rhibiscusc]

My issue is similar to the problem described here: https://stackoverflow.com/questions/56291169/slack-get-thread-id-after-posting-message-using-incoming-web-hook

I am currently using slack as our new service notification hub. But I like to organize the notification per a specific event id. So when the service is going to persist the ts value for the first message related to the event id and put subsequent message in the thread.

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!

As Ashly mentioned, you can utilize other web APIs to fetch the data. Another suggestio is to switch to chat.postMessage API rather than using an incoming webhook. The chat.postMessage API response provides the posted message's channel ID and ts. This should be the most straight-forward way to achieve your goal.
