Workflow Triggers

Relay.app workflows can be initiated via multiple trigger types:

• App-based triggers: React to events in connected apps (e.g., new Gmail email, HubSpot deal stage change, Stripe payment received).
• Schedule triggers: Cron-style scheduling (e.g., every weekday at 5 PM, every 15 minutes).
• Webhook trigger: Start a run on an inbound HTTP POST to a unique endpoint.
• Mailhook: Start a run when an email arrives at a dedicated address.
• Table trigger: Start a run when a row is created or updated in a Relay.app Table.
• Form trigger: Embed a public form; each submission kicks off a workflow run with form data as inputs.
• Batch triggers: Initiate multiple workflow runs at once, on demand or on a schedule.

Key Primitives

• Sequences: Reusable step chains for common sub-processes (enrichment, routing, formatting) shareable across your team.
• Tables: Persistent structured data stores that workflows can read from and write to over time.
• MCP Servers: Build and expose custom tools via the Model Context Protocol, making them callable by external AI apps (ChatGPT, Claude, ElevenLabs).
• Branch Merging: After conditional paths, converge back into a single common flow — no duplicated steps.
• Dynamic Waiting: Pause a run for a duration, until a date, or until a condition changes in another app.
• Portable Rich Text: Generate formatted outputs usable across email, chat, and docs regardless of whether the target expects HTML or Markdown.
