📝 WalkthroughWalkthroughChangesZoho Inventory integration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to This integration can send a Zoho bearer token to an untrusted host selected from OAuth response data, potentially exposing the connected account's data. Organization routing is also not explicitly bound to the tenant credential, and regional authentication and rate-limit handling have bounded correctness issues; merge should wait for the host restriction and tenant-binding concerns to be addressed.

Greptile SummaryThe PR adds a publishable Zoho Inventory plugin with regional OAuth, organization-based tenant linking, schemas, error handling, and read endpoints.
Confidence Score: 1/5The PR is not safe to merge until the OAuth domain trust issue, ignored API-domain configuration, and missing endpoint-level tests are addressed. The resolver can send a fresh OAuth token to an unvalidated callback-derived URL, custom API-domain configuration is silently ignored by every endpoint, and the endpoint implementations have no execution-level tests to catch request-mapping defects. Files Needing Attention: packages/zohoinventory/webhooks/oauth-tenant-link.ts, packages/zohoinventory/client.ts, packages/zohoinventory/endpoints/*.ts, packages/zohoinventory/api.test.ts

| Filename | Overview |
|---|---|
| packages/zohoinventory/client.ts | Adds regional request construction and refresh retry, but endpoint callers fail to forward the custom domain and domain validation is absent. |
| packages/zohoinventory/webhooks/oauth-tenant-link.ts | Discovers an organization after OAuth but can transmit the access token to an unvalidated domain. |
| packages/zohoinventory/index.ts | Assembles endpoint, schema, metadata, OAuth, managed-auth, and error-handler contracts; its public API-domain option is not honored by endpoint handlers. |
| packages/zohoinventory/endpoints/types.ts | Defines aligned Zod input and output contracts for the four read endpoints. |
| packages/zohoinventory/api.test.ts | Covers helpers, schemas, resolver behavior, errors, and refresh retry but does not execute the endpoint handlers. |
| packages/corsair/core/constants.ts | Consistently registers the new provider ID, display name, and provider type. |

When an application configures apiDomain, this handler and the other three endpoint handlers forward only region, so the client falls back to the region-derived Zoho host and requests through the configured custom domain fail or reach the wrong service.

When callback parameters supply api_domain and the token response does not replace it, the resolver accepts the URL without scheme or host validation and sends the new access token in its Authorization header, enabling token disclosure and server-side requests to an attacker-selected host.
How this was verified: The callback-data merge feeds tokens.api_domain into an unrestricted URL builder whose result is fetched with the OAuth token attached.

These assertions only confirm that the four endpoint properties are functions; no test invokes a handler with a mocked transport, so incorrect paths, methods, query mapping, response transformation, or event logging can pass the package suite and fail for consumers.

Restrict and consistently apply the API host before sending OAuth credentials.
The OAuth response's api_domain currently influences the request base for an authenticated /organizations call without being restricted to canonical HTTPS Zoho origins. HTTPS-only validation is insufficient if an arbitrary HTTPS host can receive the bearer token. Validate the host against the regional Zoho mapping or an explicit allowlist, and forward the validated configured apiDomain to all authenticated endpoint requests so routing cannot be silently ignored.

Preserve retryAfter through Zoho error normalization.
makeZohoInventoryRequest replaces ApiError with ZohoInventoryAPIError and drops retryAfter. The rate-limit handler therefore cannot pass the server retry interval to headersRetryAfterMs.

Zoho Inventory API OAuth regional domains Canada accounts.zohocloud.ca zohoapis.ca official documentation
💡 Result:
For Zoho Inventory users hosted in the Canada data center, the official regional domains for OAuth and API requests are as follows: OAuth Authentication: Use https://accounts.zohocloud.ca/ for generating access and refresh tokens [1][2][3]. API Base URI: Use https://www.zohoapis.ca/inventory/ for making Zoho Inventory API calls [4][5]. Technical Integration Details: Zoho Inventory utilizes a multi-data center architecture where the API endpoints and authentication servers are domain-specific [4][6]. You must ensure your application directs requests to the correct Canadian domain to maintain compliance with data residency requirements [6]. When performing OAuth 2.0 operations, replace the standard.com accounts URL with the Canada-specific https://accounts.zohocloud.ca/ [1][3]. Similarly, replace the base API URI with https://www.zohoapis.ca/ [4][5]. To verify your specific domain, you can check the URL of your Zoho Inventory web application; if it contains inventory.zoho.ca, your organization is hosted in the Canada data center [4][5]. It is recommended to dynamically handle these domains by using the api_domain returned in your access token response rather than hardcoding URLs [7][2].

Use the Canada-specific OAuth host.
When region: 'ca', zohoInventoryOAuthAuthUrl and zohoInventoryOAuthTokenUrl build accounts.zoho.ca, but Zoho requires accounts.zohocloud.ca. Update the mapping and this overview text. The zohoapis.ca API host remains correct.
