08 — Integration FAQ
Answers,
straight through.
Q.01Can I connect my ERP?+
Yes. Because Relay runs on your infrastructure and exposes REST APIs and webhooks, connecting ERPs like SAP, Odoo, NetSuite, or a custom system is straightforward. Our engineering team can build the integration for you if preferred.
Q.02Can I connect accounting software?+
Yes. Invoices, receipts, and customer records can move between Relay and accounting platforms such as Tally, Zoho Books, or QuickBooks through REST APIs and event webhooks.
Q.03Can I build my own integration?+
Yes. Every core action in Relay is available through documented REST endpoints and webhook events. Your engineers can build against them without waiting for anyone.
Q.04Does Relay expose REST APIs?+
Yes. Every module — contacts, conversations, pipelines, automations — has a documented REST surface with typed responses and versioning.
Q.05Are webhooks available?+
Yes. Webhooks are signed with HMAC, delivered with retries, and idempotent. Subscribe to the events that matter to your workflows.
Q.06Can you build integrations for us?+
Yes. Our engineering team builds custom integrations directly into your installation. The integration becomes part of your platform and stays under your ownership.
