A practical field guide from Automation Ace.
Short answer: use a managed OAuth app (provided by platforms like Composio, Nango, Pipedream Connect, or Arcade) to prototype, for internal tools, and for long-tail apps where speed matters more than branding. Use your own OAuth client when customers will see the consent screen, you need scopes or rate limits the managed app does not offer, enterprise customers will review the integration, or the provider requires a verified app. Many teams start managed and move their most important providers to their own clients before or at launch.
Short answer
- Managed: fastest, no provider reviews, shared limits, another company's name on consent.
- Your own: your brand, your scopes, your quotas, your reviews.
- Mix: own clients for core apps, managed for the long tail.
- Plan the switch: users usually need to reconnect when the client changes.
What an OAuth client is
An OAuth client (or OAuth app) is your registration with a provider such as Google, Microsoft, Slack, or HubSpot. It has a client ID, a secret, approved redirect (callback) URLs, and the scopes it may request. Tokens a user grants are issued to that client. A managed auth platform still stores and refreshes the tokens in both cases; the question is only whose client issued them. Terms explained: API credential and authentication terms.
Managed app vs your own client
| Managed OAuth app | Your own OAuth client | |
|---|---|---|
| Who registers it | The auth platform | You, in each provider's developer portal |
| Consent screen shows | The platform's app name (or a generic one) | Your app name and logo |
| Setup time | Minutes | Hours to weeks (reviews for some providers) |
| Provider reviews | Handled by the platform | Yours (for example Google verification for sensitive scopes) |
| Scopes | Limited to what the managed app supports | Any the provider allows you |
| Rate limits and quotas | Often shared with other customers of the platform | Dedicated to you |
| Callback URL | The platform's | The platform's or your own domain |
| Portability | Tied to the platform | You keep the client if you switch platforms (users may still need to reconnect) |
| Best for | Prototypes, internal tools, early-stage products, long-tail apps | Production products, sensitive scopes, high volume, enterprise customers |
Signs it is time for your own client
| Use your own OAuth client when… | Why |
|---|---|
| Customers will see the consent screen | Your brand builds trust; another company's name confuses users |
| You need scopes the managed app does not request | Only your client can ask for them |
| You hit shared rate limits or quotas | Your client gets its own limits |
| Enterprise customers review integrations | Security teams want to see your app registered with the provider |
| The provider requires a verified or listed app | Marketplace listings and partner programs are tied to your client |
| You may change platforms later | Owning the client reduces lock-in |
How each platform handles it
| Platform | Managed option | Your own client |
|---|---|---|
| Composio | Composio-managed OAuth apps by default | Custom auth configs with your client ID, secret, and scopes |
| Nango | Nango-managed OAuth apps for many providers, usable in production per Nango | Your client ID and secret with Nango's callback URL, or your own domain via a redirect |
| Pipedream Connect | Pipedream's OAuth clients | Your own OAuth client for an app |
| Arcade | Default providers for some apps | Custom OAuth providers configured in the dashboard or config |
| Zapier MCP | Zapier's own app connections | Not applicable; uses Zapier's integrations |

Callback URLs and branding
- With your own client, you register the platform's callback URL with the provider.
- Some platforms let you use a callback on your own domain that redirects to theirs (Nango documents a 308 redirect approach), so users see your domain.
- Set this up before real users connect; changing callback URLs later can break new connections and reconnects until provider and platform settings match.
- Google and some other providers put apps in a testing mode with short-lived refresh tokens until you publish or verify; plan for it.
Switching later
Moving a provider from a managed OAuth app to your own client
1. Register your OAuth app with the provider; add the platform's callback URL
(or your custom callback domain that redirects to it).
2. Request the scopes you need; start verification early if required.
3. Create a new auth config / integration with your client ID and secret.
4. Send NEW connections to it.
5. Ask existing users to reconnect (tokens issued to one client can't be
moved to another), or keep both configs until they do.
6. Retire the managed config when no connections use it.Track which users are on which config so you can prompt them; see managing app connections for a multi-user agent.
A practical recommendation
- Prototype everything on managed apps.
- Before launch, register your own clients for the two or three apps most customers will connect, especially Google and Microsoft.
- Keep managed apps for low-volume, long-tail providers.
- Revisit when you hit limits, add sensitive scopes, or sell to enterprises.
Next: calling APIs without managing tokens and giving agents access without tokens.
Frequently asked questions
What is a managed OAuth app?
An OAuth client that a managed auth platform has registered with a provider and lets its customers use, so you can connect users without registering your own app or going through provider reviews.
When should I use my own OAuth client instead of a managed one?
When customers see the consent screen, you need scopes or rate limits the managed app doesn’t provide, enterprise customers review your integrations, the provider requires a verified app, or you want to reduce lock-in.
Can I use a managed OAuth app in production?
Often yes. Some platforms, such as Nango, state their managed apps can be used in production. Consider branding, shared rate limits, and scope limits before relying on one for a core integration.
Do users have to reconnect if I switch to my own OAuth client?
Usually yes, because tokens are issued to a specific client and cannot be moved to another. Send new connections to the new config and prompt existing users to reconnect.
Does using my own OAuth client mean I store tokens myself?
No. Managed auth platforms can still store and refresh tokens issued to your own client. You own the registration; they handle the token lifecycle.
Disclaimer: Managed app auth platforms, their SDKs, endpoints, plans, and features change quickly; details reflect public documentation and coverage at the time of writing, so confirm current details with each provider before building.
