Developers
Build on NEXTOREx
A secure, versioned REST API for your own software: read and create CRM leads, ERP customers and products and Education students, check your subscription and invoices, and receive signed webhooks.
Server-to-server keys
Bearer API keys with scopes, expiry, rotation and instant revocation. A key never acts as a super-user.
Same rules as the product
A key can only do what its role, your purchased apps, your company and your hierarchy allow.
Safe writes
An Idempotency-Key on every POST, strict field contracts and no deletes.
Signed webhooks
HMAC-SHA256 signatures, replay protection, automatic retries and event de-duplication.
Base URL
https://api.nextorex.com/api/public/v1The public catalog (GET /catalog) needs no key. Everything else needs a Developer API key, and Developer API access must be enabled on your NEXTOREx account.
