Yes when systems expose APIs, files, or message buses with stable identities. We integrate CRM, PMS, WMS, telephony, SharePoint successors, and custom SQL stores. Adapters normalize IDs before models see them. Event streams keep AI from brittle screen scraping. When only batch CSV exports exist, we design safe drop zones with validation.
Legacy constraints appear often around on-prem auth and rate limits. We place middleware that retries carefully and logs payloads for audit. Middleware never stores secrets in chat history. Role filters mirror existing Active Directory groups when portals sit in front. Payload CMS migrations prove department ACL strategies after SharePoint exits.
Voice products hang on SIP trunks or cloud telephony webhooks. Customs and legal document flows need object storage with retention locks. Real estate feeds require freshness stamps and backoff on provider quotas. HR pre-screening agents write structured scores back into ATS fields only, not free text dumps. Each pattern chooses boring transport over novelty.
Integration risk drops when you handsample requests and error catalogs early. We try contract tests so provider changes fail CI. Feature flags let reverse traffic if a vendor API flops. Monitoring watches auth error spikes as first signal. Fredericksburg stacks are rarely greenfield, and that is fine when boundaries stay clean.
