Frequently asked questions

What is a platform app store?

A platform app store is a marketplace where developers list apps, plugins, integrations, or extensions that extend a host platform such as Shopify, Salesforce, HubSpot, or Microsoft Teams.

How do platform marketplaces differ?

They differ by ecosystem category (ecommerce, CRM, productivity), integration surfaces (embedded apps, bots, connectors), authentication models (OAuth 2.0, API keys), monetization (revenue share, listing fees), and security-review requirements.

Which marketplace is best for AI agents and bots?

Microsoft Teams Marketplace, Slack App Directory, and Salesforce AgentExchange all explicitly support agentic or bot integrations. The best choice depends on whether your users live in collaboration tools or CRM workflows.
