The icons on each card are the providers currently serving that category.

Three of your customers use three different CRMs. Without a unified API, your code branches three ways for what is conceptually one operation: create a contact. With one, you call a single endpoint and fastn routes to whichever provider that customer authorised.

One canonical endpoint per business entity, served by whichever providers your org connects.

Categories and entities

A category is a domain. An entity is a business object inside it. Each entity is backed by one or more providers. There are five categories, shown with a 5 categories chip and a Search categories box: CRM, Documents, Knowledge Base, Messaging and Project Management. A search that matches nothing reads No categories match / Try another search.

Category	Entities	Providers (slugs)
CRM	Account, Contact, Engagement, Engagement Type, Lead, Note, Opportunity, Stage, Task, User	12 providers, including hubspot, salesforce and zohoCrm
Documents	Document, Document Content	googleDocs, notion
Messaging	Channel Message, Direct Message	microsoftTeams, slack

The provider slugs are what you use in the API; the cards show display names.

Knowledge Base and Project Management are the two newest categories; their entities and providers are shown when you open them in the product.
