Is it possible to serialize the payload into a json?

[darewreck54]

Currently, the postMessage api take in a list of objects to build up the payload to send to slack.

	channelID, timestamp, err := e.slackApiClient.PostMessage(
		notification.channel,
		slack.MsgOptionUsername("Bot Name"),
		slack.MsgOptionText(titleText, false),
		slack.MsgOptionAttachments(
			slack.Attachment{
				Blocks: slack.Blocks{
					BlockSet: blocks,
				},
				Color: notification.color,
			},
		),
	)

I'm wondering:

• if it is possible to pass a json representation of the payload

In the example above, I imagine it to be something like

    e.slackApiClient.PostMessage(json)

• does the sdk support the ability to create the payload and then serialize it to a string

    jsonPayload = e.slackApiClient.CreateMessagePayload(
		notification.channel,
		slack.MsgOptionUsername("Bot Name"),
		slack.MsgOptionText(titleText, false),
		slack.MsgOptionAttachments(
			slack.Attachment{
				Blocks: slack.Blocks{
					BlockSet: blocks,
				},
				Color: notification.color,
			},
		),
	)

Thanks,
