Connect your app to Webb9 customers
Use OAuth, scoped permissions, and signed webhooks to exchange data only for businesses that install and approve your app.
Webb9 gives approved developers a reviewed path to connect customer apps, internal automations, and launch integrations through scoped API access, OAuth, and signed webhooks.
Every developer app starts with an intake form. Submissions are stored in Webb9's admin review queue and also notify the developer inbox at developers@webb9.com.
Use OAuth, scoped permissions, and signed webhooks to exchange data only for businesses that install and approve your app.
Create tenant-specific server integrations for scheduling, accounting, documents, messages, and reporting without exposing broader customer data.
Work with Webb9 review to validate callback URLs, webhook delivery, data retention, support ownership, and production readiness.
Share your company, app purpose, requested scopes, redirect URIs, webhook URLs, and security notes.
We check least-privilege scope requests, tenant isolation, customer consent, data retention, and support ownership.
Approved developers test OAuth callbacks, API calls, webhook signatures, retries, and uninstall behavior in sandbox.
Production credentials are issued after the integration passes review and the customer-facing setup path is clear.
The Webb9 API is designed around practical small-business workflows: lead intake, scheduling, service delivery, invoicing, payments, documents, messaging, and audit history.
These integrations are being planned as first-party or reviewed partner paths so businesses can connect core systems after launch.
