Devad.io Connect Slack Webhook to Devad POST Connect a Slack incoming webhook so Devad POST can publish deterministic workspace updates. ## What this channel does - Slack Webhook uses a tenant incoming webhook URL, so your workspace controls the credential. - Only superadmin-enabled and plan-allowed channels appear to tenants in POST. ## Before you start - A Slack app with Incoming Webhooks enabled. - A channel selected for the webhook. - A POST plan that includes Slack Webhook. ## Connect in Devad POST - Open `/workspaces/apps/post/channels` and choose Slack Webhook. - Incoming webhook URL: paste the Slack URL that starts with `https://hooks.slack.com/services/`. - Name: optional display name for the connected Slack channel. - Save the connection and confirm the channel appears as connected. ## Publish with this channel - Select the connected Slack channel. - Write the message and optionally attach an image URL or supported image media. - Publish through the POST queue. ## Common fixes - `invalid_payload`: remove unsupported blocks or very large text. - `no_service` or `channel_not_found`: recreate the webhook in Slack. ## Security notes - Never paste tokens, webhooks, passwords, or API keys into tickets, screenshots, public docs, or AI prompts. - Use a credential dedicated to Devad POST and revoke it if access changes. - Use HTTPS endpoints only.
