Don't overpay for features you won't use. Here's our recommendation based on your use case:
Most AI tools, including many in the messaging & communication category, offer special pricing for students, teachers, and educational institutions. These discounts typically range from 20-50% off regular pricing.
• Students: Verify your student status with a .edu email or Student ID
• Teachers: Faculty and staff often qualify for education pricing
• Institutions: Schools can request volume discounts for classroom use
Most SaaS and AI tools tend to offer their best deals around these windows. While we can't guarantee Slack API runs promotions during all of these, they're worth watching:

Starting at Pay-per-use
Acknowledge the event immediately with a 200 response, then process the LLM call asynchronously. Post the agent's response as a new message or update the original message when the LLM responds. Bolt framework handles this pattern with ack() + async processing.
Yes, using the conversations.history API method. The agent needs the channels:history (public) or groups:history (private) scope. On free Slack plans, only the most recent 90 days of messages are accessible via API.
Unlimited. A single Slack app can be installed in any number of workspaces. Each installation provides a workspace-specific OAuth token. For multi-tenant AI agents, manage tokens per workspace and route events accordingly.
Events API uses webhooks (Slack POSTs to your URL). Socket Mode uses WebSockets (your app connects to Slack). Socket Mode doesn't require a public URL, making it easier for development and behind-firewall deployments. For production, Events API is recommended for reliability.
