slack got more fragile for distributed openclaw rollouts

Summary

Slack has significantly tightened its API limits for commercially distributed, non-marketplace applications using `conversations.history` and `conversations.replies`, reducing them to 1 request per minute with a 15-object cap for new apps and installs. Internal customer-built apps retain higher limits of 50+ requests per minute and up to 1,000 objects. This creates a dual reality for OpenClaw builders, particularly those deploying commercial agents into client workspaces. Additionally, recent OpenClaw issue traffic indicates Slack-specific breakage, where connections appear healthy but inbound events fail to arrive, exemplified by issue #57844. Despite these challenges, Slack remains a preferred platform for agent deployment due to its pervasive use in existing team workflows, offering robust controls for managing agent interaction surfaces.

Key takeaway

For AI Engineers deploying OpenClaw into client Slack workspaces, you must adopt a "thin Slack" operating model. Prioritize OpenClaw's internal memory for long-lived context and configure Slack as a controlled intake layer using pairing for DMs, allowlists for channels, and mention gating. Your post-upgrade validation must include real inbound message tests, not just status checks, to confirm event delivery and prevent silent failures under the new, stricter API limits.

Key insights

Slack's tightened API limits and recent transport regressions necessitate a more disciplined approach to OpenClaw deployments.

Principles

• Placement beats separate dashboards for agent adoption.
• Slack should be an intake layer, not a memory layer.
• Explicit allowlists and mention gating enhance control.

Method

Configure OpenClaw for Slack with `dmPolicy: "pairing"`, `groupPolicy: "allowlist"`, `requireMention: true`, `session.dmScope: "per-channel-peer"`, and `thread.historyScope: "thread"` to create a controlled intake surface.

In practice

• Use OpenClaw workspace for long-lived context.
• Isolate DM contexts with `session.dmScope: "per-channel-peer"`.
• Perform real inbound smoke tests after upgrades.

• Slack API Policy
• OpenClaw Integration
