Description

Adds the official 2Chat integration plugin (@corsair-dev/twochat) to Corsair following repository plugin standards and the approved API surface from corsair.dev/oss.
Fixes #744

Endpoints Implemented

  • contacts.createContact (POST /open/contacts): Create a new contact with phone, email, or address details.
  • contacts.listContacts (GET /open/contacts): Paginated retrieval of contacts directory.
  • account.getApiUsageInfo (GET /open/info): Retrieve account quota, consumption metrics, and rate limit info.
  • account.testApiKey (GET /open/info): Validate API key connectivity and account status.
  • webhookSubscriptions.listWebhooks (GET /open/webhooks): List all configured webhook subscriptions in 2Chat.

Architecture & Standards

  • Authentication: API Key auth via X-User-API-Key header with base URL https://api.p.2chat.io.
  • Client: Configured RateLimitConfig with exponential backoff and retry handling.
  • Error Handlers: Complete coverage — RATE_LIMIT_ERROR (429), AUTH_ERROR (401), PERMISSION_ERROR (403), NETWORK_ERROR, and fallback DEFAULT.
  • Validation: Strict Zod input and output schemas with full TypeScript type exports.

Checklist

Additional Notes

  • No inbound webhooks: Per spec, webhooks: {} is exported to satisfy the CorsairPlugin type contract. Webhook subscription management is exposed as a regular read endpoint (listWebhooks).
  • New package: packages/twochat registered in packages/corsair/core/constants.ts.
  • pnpm run validate:plugins: [SUCCESS] All plugins passed structural validation!
  • Tests: 28 passed, 28 total across api.test.ts and schema.test.ts.

Greptile Summary

The PR adds the new 2Chat provider plugin and now addresses both previously reported issues.

  • Adds contact creation/listing, account information, API-key testing, and webhook-subscription listing.
  • Preserves HTTP status and retry metadata when wrapping provider errors.
  • Adds behavioral endpoint tests covering request dispatch and client error handling.

Confidence Score: 5/5

The PR appears safe to merge because both previously reported blocking failures have been addressed and no blocking failure remains.

No blocking failure remains.

📝 Walkthrough

Walkthrough

The PR adds a TwoChat provider package with five API endpoints, API-key authentication, Zod schemas, retry and error handling, webhook utilities, tests, package configuration, demo wiring, and shared provider registration.

Package and schema scaffold
packages/twochat/package.json, packages/twochat/tsconfig.json, packages/twochat/tsup.config.ts, packages/twochat/schema/*, packages/twochat/schema.test.ts
Adds package metadata, build configuration, TypeScript configuration, entity schemas, and schema tests.
API contracts and endpoint transport
packages/twochat/endpoints/types.ts, packages/twochat/client.ts, packages/twochat/error-handlers.ts, packages/twochat/endpoints/*, packages/twochat/client.test.ts
Adds Zod endpoint schemas, typed handlers, authenticated requests, rate-limit retries, error handlers, endpoint exports, and client tests.
Plugin assembly and webhook handling
packages/twochat/index.ts, packages/twochat/webhooks/*
Wires endpoints, schemas, metadata, API-key authentication, error handlers, key resolution, and tenant matching.
Provider validation and registration
packages/twochat/api.test.ts, packages/twochat/jest.config.cjs, demo/testing/package.json, demo/testing/src/server/corsair.ts, packages/corsair/core/constants.ts
Adds provider tests, demo registration, test configuration, and shared provider declarations for twochat.

Estimated code review effort: 4 (Complex) | ~60 minutes

Mergeability Score: 🟡 Moderate · up to fa9ad

The new 2Chat plugin adds contact, account, and webhook operations, but the current head still risks exposing contact data in metadata, failing builds on Windows, rejecting valid contact responses, and creating conflicting demo registration behavior. These issues should be fixed or explicitly accepted before merge.

9-16: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

Make the entity test assert the required contract.

The assertion on Line 12 is always true because Object.keys always returns an array. The loop on Lines 13-15 performs no checks for the current empty map. The test therefore passes when every entity schema is missing. Assert the expected entity keys and parse representative records. If the provider is intentionally stateless, assert that TwoChatSchema.entities equals {} instead.

Use a cross-platform build cleanup command.

If a contributor runs pnpm build from the default Windows shell, rm -rf dist is unavailable. The build stops before tsc or tsup runs. The PR verification uses Windows, so the build path should support that environment.

Add rimraf to devDependencies, or replace the cleanup step with a Node-based filesystem command.

Hey @akshatmalik-bruh, thanks for the contribution! 🏴‍☠️ Before a maintainer reviews, please fix the items below — the review re-runs automatically on your next push.

Must fix

  • P1 packages/twochat/client.tsHTTP error metadata is discarded
    When 2Chat returns an exhausted 429, 401, or 403 response, this wrapper preserves only the message and discards the ApiError status and retryAfter fields. The status-based handlers therefore cannot match, Retry-After cannot be honored, and messages without the fallback keywords are handled as generic non-retryable errors.

Rule Used: Every endpoint must validate inputs and outputs wi... (source)

Knowledge Base Used: The provider-plugin package pattern

  • P1 packages/twochat/api.test.tsEndpoint behavior remains untested
    These tests only verify that five function references exist, while the schema tests parse static objects without invoking the endpoints. Incorrect paths, HTTP methods, request bodies, pagination queries, key forwarding, or event logging therefore leave the suite green, contrary to the requirement that every implemented endpoint have a real behavior test.

Rule Used: Flag any types on exported or public surfaces as... (source)

Knowledge Base Used: The provider-plugin package pattern

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

If anything remains after your next push, a bot commit will clean it up; a maintainer always does the final review and merge.

268-272: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

⚠️ Unverified finding
Sandbox verification was unavailable.

Assert the parsed default values.

This test only verifies that an empty input is accepted. It does not verify that listContacts applies its documented defaults. Capture the parse result and assert the expected pagination values.


282-300: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

⚠️ Unverified finding
Sandbox verification was unavailable.

Add explicit HTTP-status matching cases.

The test names claim coverage for 429, 401, and 403. The supplied errors contain only message text. Add errors with the status representation used by error-handlers.ts. Otherwise, status-code matching can regress while these tests still pass.

3-25: 🗄️ Data Integrity & Integration

⚠️ Unverified finding
Sandbox verification was unavailable.

Verify that entity schemas do not discard provider fields.

The contact response includes channel_uuid and details. The webhook response includes hook_params. These fields are absent from the entities. Zod z.object() strips unrecognized keys by default, so direct parsing can silently discard provider data. Add the fields, or explicitly map the full provider response to this reduced entity and test that projection. (developers.2chat.co)


27-31: LGTM!


4-4: 🗄️ Data Integrity & Integration

Validate 2Chat identifier and URL fields.

z.string() accepts arbitrary text for uuid, channel_uuid, and hook_url. Use schemas for the documented CON, WHK, WPN, and WAN prefixes, and use a URL schema for hook_url. Keep profile_pic_url nullable if API responses can contain null. Add valid and invalid fixtures.

63-65: 🗄️ Data Integrity & Integration

⚠️ Unverified finding
Sandbox verification was unavailable.

Verify that rate-limit retries do not repeat contact writes.

TWOCHAT_RATE_LIMIT_CONFIG is passed for every request method. The provider includes a POST contact-creation endpoint, and 2Chat documents both 201 contact creation responses and automatic retries for 429 responses. If the shared executor retries POST, an ambiguous response can repeat the create or update side effect. Restrict retries to idempotent methods, or confirm an idempotency mechanism and add a POST retry test. (developers.2chat.co)


63-65: 🩺 Stability & Availability

⚠️ Unverified finding
Sandbox verification was unavailable.

Confirm that the shared request layer enforces a finite timeout.

This call does not provide a timeout or AbortSignal. If the shared request layer has no finite default, a stalled provider connection can keep the plugin operation pending. Confirm the timeout contract and add one if absent.

2Chat API Contacts list contacts profile_pic_url null response

💡 Result:

In the 2Chat API, receiving a null value for the profile_pic_url field when listing or retrieving contacts is expected behavior [1][2]. This indicates that the contact does not have a profile picture associated with their account in 2Chat [1]. According to the official 2Chat API documentation, the profile_pic_url field is included in the contact object response [1][2]. If no image is available or assigned to that contact, the API returns null [1][2]. This applies to various contact-related endpoints, including: - List Contacts: Returns a list of contacts where profile_pic_url may be null for individual entries [1]. - Get Contact: Retrieves a specific contact, which may also return null for this field [2]. This behavior is consistent across the platform's contact management system [1][3][2]. If you are developing an integration, your application should be designed to handle null values for this field gracefully (e.g., by displaying a default placeholder image) [1][2].

site:developers.2chat.co/docs/API/Contacts/list-contacts profile_pic_url

💡 Result:

The term profile_pic_url is a common key used in software engineering and API development to represent the web address (URL) of a user's profile picture [1]. It is not a formal global standard, but rather a naming convention widely adopted by developers for JSON objects, database schemas, and API responses to store or retrieve the location of an image file associated with a user profile [1]. When used, the field typically contains a string value representing a direct link to an image file (e.g., hosted on a cloud storage service like Amazon S3) or a null value if no profile picture has been set [1].

🌐 Web query:

Zod 4.1.13 z.url nullable optional documentation

💡 Result:

In Zod, you can make a URL schema optional or nullable by chaining the standard modifier methods .optional(), .nullable(), or .nullish() to the z.url() schema [1][2]. - z.url.optional: Allows the value to be a valid URL or undefined [1][3]. - z.url.nullable: Allows the value to be a valid URL or null [1][3]. - z.url.nullish: Allows the value to be a valid URL, null, or undefined [3][4]. If you find that your schema is not accepting these modifiers, ensure you are chaining them correctly directly to the z.url() call [5][6]. For example: const optionalUrl = z.url.optional; const nullableUrl = z.url.nullable; const nullishUrl = z.url.nullish; These modifiers return a new Zod schema instance that permits the respective "lack of value" types while maintaining the underlying URL validation logic [1][2][3]. If you previously used.optional.nullable,.nullish is the recommended shorthand [4].

Citations:


Accept null for profile_pic_url.

The 2Chat Contacts API returns profile_pic_url: null when no profile image exists. z.string().optional() rejects this valid response. Use z.url().nullable().optional() and add a null fixture in packages/twochat/schema.test.ts.

recursive call to enforce a single combined retry budget for 429 responses,
rather than multiplying transport and endpoint retries. Ensure the recursive
retry path returns and awaits call(...) so a successful retry result is
propagated instead of rethrowing the original error; preserve normal successful
and non-429 error behavior.

Bound the combined 429 retry budget and return retry resultsrequest() allows four transport attempts, while RATE_LIMIT_ERROR.maxRetries: 5 allows six endpoint calls. A persistent 429 can cause 24 transport attempts. The dispatcher also discards a successful recursive retry because it does not return await call(...), then throws the original error.
