Like Discord, Slack uses a webhook-based approach for posting messages.

​
Quirks & Gotchas

​
Webhook-Based Posting

Slack requires you to connect a workspace and select channels. We use incoming webhooks to post messages.
  • You must be a workspace admin to connect.
  • Posts appear as a bot message in the selected channel.

​
Channel Selection Required

You must specify a channelId in your post data. Available channels are in socialAccount.channels.

​
Generous Character Limit

Slack allows up to 30,000 characters per message-much more than most platforms.

​
Custom Bot Identity

Like Discord, you can customize the bot appearance:
  • username: Up to 80 characters.
  • avatarUrl: A URL to an image for the bot’s avatar.

​
