📝 WalkthroughWalkthroughThe PR adds the ChangesCampayn plugin
Estimated code review effort: 3 (Moderate) | ~30 minutes Merge Risk: 🟠 High · up to The new Campayn integration cannot currently reach Campayn, uses the wrong authentication format, and accepts forged webhook events because signature verification always succeeds. These issues can prevent normal provider operation and allow unauthenticated event processing, so the PR is not ready to merge until they are fixed. Sequence Diagram(s)sequenceDiagram

Greptile SummaryAdds a new Campayn provider package and registers it in the core provider catalog, but the package remains largely unchanged generator output rather than a functional integration.
Confidence Score: 1/5This PR should not merge until the forged-webhook path and the nonfunctional generator placeholders are removed or fully implemented. The package exposes an endpoint that targets a placeholder host with incompatible authentication and registers a webhook verifier that accepts attacker-controlled events without checking a signature; its implemented endpoint also lacks required endpoint-level tests. Files Needing Attention: packages/campayn/webhooks/types.ts, packages/campayn/client.ts, packages/campayn/index.ts, packages/campayn/schema.test.ts
|
| Filename | Overview |
|---|---|
| packages/campayn/client.ts | Adds the HTTP client, but it targets a placeholder host and uses the wrong authorization scheme for Campayn. |
| packages/campayn/index.ts | Registers the package's endpoint, webhook, authentication, and tenant-routing surfaces despite several remaining generator placeholders. |
| packages/campayn/webhooks/types.ts | Defines webhook schemas and matching but implements signature verification as unconditional success. |
| packages/campayn/schema.test.ts | Tests only schema metadata and does not exercise the exposed endpoint. |
| packages/corsair/core/constants.ts | Correctly adds Campayn to the provider list, display-name map, and provider type union. |

When an attacker submits an example payload with any x-campayn-signature header, this verifier accepts it without examining the signature or secret, causing the forged event to be persisted and acknowledged as successful.
How this was verified: The request-controlled header and event type reach a verifier that always returns valid before the handler persists the supplied payload.

There was a problem hiding this comment.
When a consumer calls the registered example.get endpoint, the client targets api.example.com and serializes the API key as Bearer authentication rather than Campayn's required TRUEREST apikey= format, causing the exposed endpoint to contact the wrong service with incompatible credentials. The registered webhook and tenant-routing surfaces also retain unresolved generator stubs.

The package registers example.get, but its only test exercises schema metadata and never invokes the endpoint, leaving its request construction, authentication, response handling, and error behavior without the endpoint assertions required for plugin packages.

Replace the placeholder API base URL.
Every endpoint call targets https://api.example.com, not Campayn. The current plugin cannot reach Campayn. Configure the real Campayn API base URL before exposing the provider.

Description
Adds initial scaffold for a Campayn integration plugin. Campayn is an email marketing platform that allows users to create, send, and manage email campaigns.
Implemented so far:
pnpm run generate:plugin Campaynapi_keytype — Campayn authenticates via an API key, account-scoped (account: ['one'])Planned scope for full implementation:
Note on auth: Campayn uses a non-standard authorization header format —
Authorization: TRUEREST apikey=<key>— rather than a typical Bearer token, which client.ts will need to account for.Fixes #
Checklist
pnpm lintand all checks passpnpm typecheckand there are no TypeScript errorspnpm buildand all packages build successfullypnpm testand all tests passScreenshots / Demos (if applicable)
N/A — no UI/CLI output changes yet, backend plugin scaffold only.
