Connectors that need approval
Which integrations require developer registration or app review before they work, and how long each takes.
Most connectors work the moment you paste a credential. A minority do not. The vendor has to approve a developer account, review your app, or grant a production token first, and that can take days or weeks.
Plan around these before you commit to a launch date.
| Connector | What needs approving | Typical wait | Cost |
|---|---|---|---|
| Google Drive | OAuth scope verificationThe broad Drive scopes (drive, drive.readonly, drive.metadata, drive.activity) are Google restricted scopes, which need OAuth app verification plus an annual third-party CASA security assessment from a Google-approved assessor before the app can serve the public. | Google says restricted scope ver… | Verification itself is free |
| Etsy | App reviewWhich gate you hit depends on app type. Etsy's docs say Seller Apps are approved automatically for eligible sellers, but a Personal App "goes through a deeper review process than Seller Apps", and serving sellers at production scale needs a separately reviewed Commercial Access upgrade. | Seller App: Etsy states eligible… | Free |

What the categories mean
Developer token approval. The vendor issues a token immediately, but it only reaches test data until they approve production access. Google Ads works this way.
App review. You submit the app for human review before it can request the permissions you need. Common on the social platforms.
Developer account approval. You must be accepted into a developer or partner programme before any credential exists at all.
OAuth scope verification. The credential works, but the vendor restricts the sensitive scopes until your app passes verification. Some restricted scopes require a paid third-party security assessment.
Seller or marketplace approval. Tied to your selling account rather than your app.
Paid plan required. No review, but the API is not available on lower tiers.
Working while you wait
Several gated connectors let you build against test or sandbox data immediately. Where that is possible, the connector's own page says so under Works meanwhile.
Start the approval application first, then set up everything else while it is in the queue. The application is almost always the long pole.
