Create application channels via the Core API

You can now create application channels programmatically, without manual setup in the Front UI for every new channel your app needs. This unlocks fully automated provisioning flows so your integration can spin up channels as customers onboard or as new use cases emerge.
 

POST /inboxes/:inbox_id/channels
 

To create an application channel, send a request with:

• type set to custom
• application_uid set to the developer app that defines the channel
• credentials matching your application server's authentication type (API key, basic, bearer, or OAuth2 variants)

For OAuth2 authorization_code flows, omit credentials and complete the OAuth flow interactively after the channel is created.
 

Full parameter details, credential shapes, and examples are in the reference docs.
 

Happy coding!
