Integrations
Connect your agents to the tools your business already uses via OAuth. Google, Microsoft, Shopify, Stripe, Calendly, and more.
Integrates with your tech stack
Custom Agents uses Nango.dev as its integration backbone, providing secure OAuth-based connections to the tools your business already uses. Click connect, authorize, done. No API keys to manage.
How agents use integrations
Your agent uses integrations as tools within conversations:
- Customer asks "Where is my order?" → agent checks Shopify and responds with tracking
- Prospect wants to book a call → agent checks Google Calendar and offers available times
- Client needs a payment receipt → agent pulls it from Stripe and sends it
You control which integrations each agent can access, maintaining granular control over permissions.
Available integrations
Each integration gives your agent specific actions it can take autonomously during conversations.
Shopify
Google Calendar
Google Contacts
Google Drive
YouTube
SlackMCP Support
Custom Agents also supports the Model Context Protocol (MCP) — an open standard for connecting agents to external tools. This makes integrations more reliable, standardized, and easier to extend.
Built-in CRM
Every conversation automatically populates your contact database. Full history, relationship context, and interaction logs — without lifting a finger.
Knowledge Base
Teach your agent about your business with documents, FAQs, and SOPs. The agent references this information in every conversation.
