FAQ
Can you integrate any system with any other system?
Yes, if both systems provide an API REST, SOAP, GraphQL, JSON-RPC or webhooks. We confirm feasibility before you order.
Which Odoo versions do you support?
Odoo 14 to 18, Community and Enterprise, on Odoo.sh, Odoo Online or self-hosted.
Do I need a paid connector app or middleware like Zapier?
No. We build a direct custom integration, so there are no monthly connector fees unless you prefer a no-code tool.
Is real-time two-way sync possible?
Yes. We use webhooks for instant updates and scheduled jobs as a backup.
What happens if one system goes down?
Failed requests are logged, queued and retried automatically, so no data is lost.
How do you keep my credentials and data secure?
We use OAuth 2.0 or scoped API keys, encrypted storage and only the permissions the integration needs.
Will I get the source code?
Yes, full source code is included in every package, plus documentation in Standard and Premium.
Can you integrate with our custom-built ERP?
Yes. If it has an API we connect to it, and if not, we can build the API layer for you.
Do you provide support after delivery?
Yes, bug fixes are covered after delivery, and we offer monthly maintenance for API changes and new features.
