## Summary
The `GET /api/v1/accounts/:id/integrations/apps` endpoint returns raw
secret values (OpenAI API keys, Google service account private keys,
Linear refresh tokens, etc.) in hook settings within the JSON response.
Although gated behind an administrator check, these secrets are visible
in the browser network tab.
This PR filters hook settings through the existing `visible_properties`
whitelist defined in `config/integration/apps.yml`, and adds explicit
whitelists to integrations that were missing them.
Closes#14042
## Bug reproduction
**Setup:** Created an OpenAI integration hook with a fake API key
(`sk-test-secret-12345`).
**Step 1 — Browser Network tab shows raw secrets:**
<img width="1676" height="869" alt="Screenshot 2026-04-24 at 14 32 28"
src="https://github.com/user-attachments/assets/6fc69463-365e-458b-b216-98a7390bf528"
/>
Navigate to Settings > Integrations as an admin. Open DevTools Network
tab and observe the response from `GET
/api/v1/accounts/:id/integrations/apps`. The hook settings contain the
full API key in plaintext:
```json
"hooks": [
{
"id": 1,
"app_id": "openai",
"settings": {
"api_key": "sk-test-secret-12345",
"label_suggestion": false
}
}
]
```
**Step 2 — API call confirms the leak:**
```bash
curl -s "http://localhost:3000/api/v1/accounts/2/integrations/apps" \
-H "access-token: <token>" \
-H "client: <client>" \
-H "uid: user@test.com" \
| jq '.payload[] | select(.id == "openai") | {id, name, hooks: [.hooks[] | {id, app_id, settings}]}'
```
Response:
```json
{
"id": "openai",
"name": "OpenAI",
"hooks": [
{
"id": 1,
"app_id": "openai",
"settings": {
"api_key": "sk-test-secret-12345",
"label_suggestion": false
}
}
]
}
```
Any admin user can extract the raw API key from the response. The same
applies to other integrations — Dialogflow exposes full Google service
account credentials, Linear exposes refresh tokens, etc.
## After fix
After applying this change, the GET
/api/v1/accounts/:id/integrations/apps endpoint no longer returns
sensitive secret values in hook settings. Instead, the response is
filtered using each integration’s visible_properties whitelist, ensuring
only safe, user-facing fields are exposed. For example, OpenAI
integrations return non-sensitive fields like label_suggestion while
excluding raw API keys. This prevents secrets from being exposed in the
browser network tab or API responses, even for authenticated admin
users.
```bash
curl -X GET "http://localhost:3000/api/v1/accounts/2/integrations/apps" \
-H "Accept: application/json" \
-H "Authorization: Bearer eyJhY2Nlc3MtdG9rZW4iOiJqZG5jOWg4TnljaWFJa3JlZkxGQzRnIiwidG9rZW4tdHlwZSI6IkJlYXJlciIsImNsaWVudCI6Ik81bjVnTDFEOVVhbGpwbWxjaHZNanciLCJleHBpcnkiOiIxNzgyMzMyNTA4IiwidWlkIjoidXNlckB0ZXN0LmNvbSJ9" \
-H "access-token: jdnc9h8NyciaIkrefLFC4g" \
-H "client: O5n5gL1D9UaljpmlchvMjw" \
-H "uid: user@test.com" \
| jq '.payload[] | select(.id == "openai") | {id, name, hooks: [.hooks[] | {id, app_id, settings}]}'

## What changed
- Added `visible_properties` accessor to `Integrations::App` model to
expose the whitelist from config
- Updated `_hook.json.jbuilder` to filter `resource.settings` through
the associated app's `visible_properties` instead of returning the full
hash
- Added `visible_properties` to integrations that were missing it:
- Linear: `[]` (settings contain refresh_token)
- Notion: `[]` (OAuth-based, no user-facing settings)
- Slack: `['channel_name']` (UI needs this to display connected channel)
- Shopify: `[]` (no settings)
App config metadata (`_app.json.jbuilder`) is left unchanged —
hook_type, settings_form_schema, etc. are not secrets and the frontend
depends on them.
## How to test
1. Create an OpenAI integration hook with an API key
2. As an admin, call `GET /api/v1/accounts/:id/integrations/apps`
3. Verify hook settings include `api_key` (whitelisted) but not raw
credential objects
4. For Dialogflow hooks, verify `credentials` (private key JSON) is
excluded while `project_id` is included
5. For Slack hooks, verify `channel_name` is still returned
6. For Linear hooks, verify `refresh_token` is not returned
