Designed as a discovery tool for feed-destination configuration — pass returned `id` values to `Destination.slackDestination.channels`. Empty when the Slack integration isn't installed for the workspace. ## OpenAPI ````yaml https://app.octolens.com/api/v2/openapi.json get /api/v2/integrations/slack/channels openapi: 3.1.0 info: title: Octolens API version: 2.0.0 description: >- The Octolens API lets you query mentions, manage keywords, and configure feeds programmatically. Every action available in the Octolens UI is available here. ### Authentication All v2 endpoints require an API key. Create one in **Settings > API** and pass it as `Authorization: Bearer `. Keys are scoped to the organization they were minted in; you cannot access another org's data. API keys carry a scope — `read`, `write` (implies read), or `admin` (implies write). Each endpoint documents the scope it needs via the `x-required-scope` OpenAPI extension and the scope badge in the docs surface. ### Rate limiting The v2 API is rate-limited at **500 requests per hour per organization**, across all keys for that org. The limit resets at the top of each hour (sliding hourly window). Every 2xx response carries three headers so clients can pace themselves: * `X-RateLimit-Limit` — the hourly cap (500) * `X-RateLimit-Remaining` — requests left in the current window * `X-RateLimit-Reset` — Unix timestamp (seconds) when the window resets When the cap is hit, the endpoint returns **429 Rate Limited** with an additional `Retry-After` header (seconds until the next window). The response body is the standard `ErrorResponse` with `code: "RATE_LIMITED"`. ### Error handling All non-2xx responses share the same `ErrorResponse` envelope: `{ error: { code, message, status, details? } }`. The `code` field is a stable `ApiErrorCode` enum — branch on it programmatically instead of parsing `message`. See the `ApiErrorCode` schema for the full catalog grouped by category. `VALIDATION_ERROR` (400) responses include a `details` array with per-field Zod issues — inspect `details[i].path` to pinpoint which input was rejected. ### Building filter bodies Endpoints that accept `simpleFilters` / `advancedFilters` (e.g. `POST /api/v2/mentions`, `PATCH /api/v2/feeds/{id}`) take a structured object that can be tricky to hand-craft. If you just have a natural-language description of what you want ("negative posts about pricing on reddit in the last week"), call `POST /api/v2/ai/filter-wizard` with that prompt and it will return a ready-to-use filter object you can pass straight through. servers: - url: https://app.octolens.com description: Production - url: http://localhost:3000 description: Local development security: - ApiKey: [] paths: /api/v2/integrations/slack/channels: get: tags: - Integrations summary: Search Slack channels description: >- Returns the workspace's accessible Slack channels filtered by name.
