Accrue Portal

Mounted customer billing portal for Accrue.

accrue_portal is the customer-facing sibling to accrue and accrue_admin. It gives host apps a package-owned portal mount for subscriptions, payment methods, invoices, and local checkout flows when a processor uses first-party-local-portal semantics.

Hex vs main: The {:accrue_portal, "~> …"} line tracks accrue_portal/mix.exs@version on the branch you are reading (typically main on GitHub). Hex.pm publishes that train after release; use HexDocs matched to the resolved Hex version when you need portal docs tied to published artifacts.

For Braintree, both checkout and billing portal sessions return mounted local URLs from your app, not upstream hosted URLs.

Phase 101 keeps the portal boundary session-resolved-customer-only. Hosts that need emailed-link checkout must add their own /checkout/start?token=... bootstrap endpoint before redirecting into the mounted portal.

Mount

import AccruePortal.Router

accrue_portal "/billing", session_keys: [:user_token]

Mount accrue_admin "/admin" and accrue_portal "/billing" as sibling scopes.

Requirements

• accrue configured with a real :repo and :auth_adapter
• host session contains the keys your auth adapter uses for Accrue.Auth.current_user/1
• portal_mount_path config matches the mounted route
• portal_base_url is set to an absolute host URL so Accrue.Billing.create_checkout_session/2 and Accrue.Billing.create_billing_portal_session/2 return absolute URLs
• Plug and LiveView mounts preserve auth/session continuity for the same customer
• Hosted Fields scripts and CSP are ready before the mounted checkout opens

Braintree local checkout

Phase 101 wires Braintree checkout through package-owned Hosted Fields. Accrue.Billing.create_checkout_session/2 returns a URL under the mounted portal path, and the checkout page completes the subscription using the same core Accrue.Billing.subscribe/3 flow as the rest of the library.

This README stays concise by design. Use accrue/guides/braintree-local-portal.md for the deeper mounted-path contract, failure semantics, sibling scope expectations, and the hand-rolled escape hatch.
