Connecting Agents to Your Systems and APIs
Quick answer
AI agents act through connections to your systems, usually APIs into your CRM, calendar and billing tools. Connect only the systems and actions each agent needs, and use the official integrations your tools already offer. Start with read-only access, add write access carefully, and require approval before actions involving money, customers or records.
An AI agent is only as useful as the systems it can reach. To book appointments, update records or answer order questions, it needs connections to your CRM, calendar, billing and other tools. Those connections decide what the agent can do, and what it can break.

This guide covers connecting agents to your systems: what an API is, choosing the connections, using what your tools already offer, limited permissions, read versus write, approvals before actions, handling errors, rate limits, logs, testing and what to measure. Put plainly: connect only what the agent needs, start read-only and require approval for actions that matter.

What an API is
A doorway into a system. Software asks for data or actions.
Rules built in. What can be read, changed and by whom.
The basics are covered in API integration.
Choosing the connections
Start from the task. Booking needs calendar access, not billing.
List each action. Look up, create, update or cancel.
Fewer is safer. Every connection adds risk.
Should agents use your tools' official connections?
Official connections first. Supported and maintained by the vendor.
Custom connections when needed. For systems without them, as in connecting your CRM to your booking system.
Limited permissions
A dedicated account for the agent. Not a person's login.
Only what each task needs. Specific records and actions.
Credentials locked up. As covered in automation security.
Read versus write
Start read-only. Answer questions before taking actions.
Add write access one action at a time. After testing.
Never delete by default. Removing records stays with people.
Approvals before actions
Money, customers and records. A person approves first.
Clear approval screens. What the agent wants to do and why.
Stop switch. As covered in agent security.
Handling errors
Fail safely. If a system doesn't respond, stop and alert.
No silent retries that double actions. Each action happens once.
Alerts when connections break. As covered in when integrations break.
Rate limits
Systems limit requests. Too many calls get blocked.
Pace the agent. Spread requests out.
Plan for busy times. Peaks shouldn't break the connection.
Logs
Every call recorded. What was requested and what changed.
Linked to the conversation. Why the agent did it.
Searchable. For audits and fixes.
Testing
Test copies of systems. Not live data, as covered in testing agents.
What the agent remembers. As covered in agent memory and context.
The bigger picture is in AI agents.
What to measure
Successful actions. Completed correctly.
Errors and failed calls. Count and cause.
Approval changes. How often people change the proposed action.
Rate limit hits. Should be rare.
Time saved. Per task, after review.
The first three months
Month one: map
List the agent's tasks, the systems each needs and the exact actions, and set up a dedicated account with limited permissions.
Month two: connect read-only
Connect to test copies, answer questions read-only and log every call.
Month three: add actions
Add write actions one at a time with approvals, error handling and alerts, then go live gradually.
