Connected services
Link provider subscriptions and API keys to Happier, reuse them across supported backends, and monitor quota snapshots where available.
Connected services let you store provider credentials once in Happier and then reuse them across supported backends and sessions.
They are different from provider authentication in provider settings:
- Connected services are stored in Happier and can be reused across compatible backends
- Provider authentication reflects the native login state of a provider CLI on one specific machine
They exist so you can:
- connect subscriptions and API keys without manually re-entering them for every backend
- keep credentials encrypted in Happier Cloud and decrypt them only on the client / daemon
- choose per-service auth at session start instead of relying only on each backend's native auth
- monitor usage / quota snapshots for supported services
- make multi-machine workflows easier when the target machine should reuse the same Happier-managed credential
What a connected service is
Happier models different credential types as distinct connected services:
openai-codex: OpenAI Codex subscription authopenai: OpenAI API key authclaude-subscription: Claude subscription authanthropic: Anthropic API key authgemini: Gemini OAuth auth
This split is intentional. Subscription auth and API-key auth have different provider behavior, billing paths, and backend materialization requirements, so Happier does not merge them into a single generic "Claude" or "OpenAI" credential type.
Where you manage them
In the app:
- Settings -> Connected services
From there you can:
- add one or more profiles for the same service
- give profiles custom labels
- set a default profile per service
- inspect profile details such as provider email, account id, and quota meters
- disconnect individual profiles
In the CLI:
happier connect statushappier connect codex ...happier connect claude ...happier connect gemini
Connection methods
OpenAI Codex
Supported methods:
- device code
- paste redirect URL
- in-app browser on native only
OpenAI Codex can also be connected with an API key, but that is modeled as the separate openai service.
OpenAI API key
Supported methods:
- manual API key entry
Use this when you want OpenAI-backed backends to run against your own API key instead of your Codex subscription login.
Claude subscription
Supported methods:
- setup-token
- paste redirect URL
- in-app browser on native only
Setup-token is the recommended default. Generate it on any machine already logged into Claude Code:
claude setup-tokenThen paste it into Happier.
Anthropic API key
Supported methods:
- manual API key entry
This is the Anthropic Console API-key path. It is separate from claude-subscription.
Gemini
Supported methods:
- paste redirect URL
- in-app browser on native only
Why web behaves differently
Happier does not use embedded OAuth capture on web. Web falls back to paste-based flows because a browser app cannot reliably auto-capture provider redirects to localhost.
Backend compatibility
Connected services are not global "works everywhere" credentials. Each backend declares which service ids and credential kinds it can consume.
| Backend | Supported connected services |
|---|---|
| Claude | claude-subscription (setup-token or OAuth), anthropic (API key) |
| Codex | openai-codex (OAuth), openai (API key) |
| Gemini | gemini (OAuth) |
| OpenCode | openai-codex (OAuth), openai (API key), anthropic (API key) |
| Pi | openai-codex (OAuth), openai (API key), claude-subscription (setup-token only), anthropic (API key) |
Important limitations:
- OpenCode does not currently accept
claude-subscription. - Pi accepts
claude-subscriptiononly when the profile is a setup-token profile, not a Claude OAuth profile. anthropicis API-key only in Happier.
Using connected services in the new-session flow
If the selected backend supports connected services, the new-session screen shows an auth picker.
That picker is dynamic:
- it appears only for backends that support connected services
- it shows only services compatible with the selected backend
- it shows only connected profiles that are valid for that backend
- it lets you choose
nativeauth orconnectedauth for each compatible service
If no compatible connected profile exists for a service, Happier keeps that service on native auth and offers a shortcut to open Connected services settings.
Connected services and browsing sessions (Codex)
For some providers, your connected-service choice affects which provider “home” Happier should use for session browsing.
The most important example is Codex:
- With native auth, Happier browses sessions from the machine’s standard Codex home.
- With a connected service profile selected for Codex, Happier browses sessions from that connected-service-backed Codex home.
This matters in two places:
- Direct → Browse provider sessions: you can explicitly choose a source/home when browsing.
- Resume ID browse: the picker is locked to the effective Codex home implied by your new-session selection so the chosen session can actually be resumed under that auth.
If you need to browse a different Codex home, switch the auth choice first and then browse again.
Connected services and session handoff
Connected services are often the easiest way to preserve session continuity across machines.
Why:
- the credential is stored in Happier, not only in one machine-local provider login
- compatible backends can materialize that credential again on another machine
- you can hand off the same Happier session and continue without depending only on native provider CLI auth on the destination
This is especially useful for:
- moving a session from one desktop/laptop to another
- moving between a host machine and a VM
- keeping continuity when only one side had previously been set up through the app
Connected services do not replace every native provider login flow. Some providers and runtimes still depend on machine-local authentication. But for supported backends, connected services are the preferred path for cross-machine continuity.
See:
Profiles, defaults, and labels
Each connected service can have multiple profiles, for example:
- a personal OpenAI subscription and a work OpenAI subscription
- multiple Anthropic API keys
- multiple Claude setup-token profiles
For each service you can:
- set one default profile
- override the default at session start
- assign a friendly label so the auth picker can show something clearer than just
workordefault
Quotas
Quota / usage surfaces are behind the connectedServices.quotas feature gate.
Current quota snapshots are available for:
openai-codexclaude-subscriptiongemini
They appear in:
- the Connected services list as badges on the effective profile
- per-profile detail screens
- the new-session auth picker for connected profiles
Each profile detail view lets you:
- refresh the snapshot
- inspect the provider plan label when available
- pin specific meters so the same meters appear as summary badges elsewhere in the UI
Security model
For OAuth-based services, Happier clients do not exchange provider codes for tokens directly.
Instead:
- the client receives an OAuth code through device auth, paste, or embedded browser capture
- the client calls Happier server
/v2/connect/<serviceId>/oauth/exchange - the server exchanges the code with the provider
- the server returns an encrypted bundle sealed to the client public key
- the client decrypts the bundle locally and stores the resulting credential record
This keeps provider secrets, including server-side OAuth client secrets, out of the UI bundle.
When a session starts, the daemon decrypts the selected records locally and materializes only the backend-specific auth it needs for that spawn.
Feature gates and overrides
Connected services uses the canonical feature-gating system.

Advanced server overrides
Most users should not need these. They are mainly for self-hosted deployments and drift reduction.

HAPPIER_CONNECTED_SERVICES_ANTHROPIC_USAGE_URL remains accepted as a fallback override for Claude subscription quota fetching, but the primary service identity is claude-subscription.
