SaaS ProvidersSalesforce, Workday, BambooHR, Greenhouse, Slack, Gmail, HubSpot, and 200+ more

​
Key Concepts

  • Initialize a ToolSet: Create a StackOneToolSet instance to access tools for providers like BambooHR, Greenhouse, Slack, and more
  • Filter Tools: Use provider glob patterns like bamboohr_*, slack_*, or salesforce_* to get specific tool sets
  • Execute Tools: Call provider APIs through StackOne tool interfaces: list employees, send messages, create tickets
  • Multi-Tenant: Each tool execution requires an accountId to identify which customer’s account to access
