Returned startTime and endTime values are whole-second UTC timestamps that can be passed directly to POST /bots/:botId/scheduling/appointments without client-side timezone conversion. ## OpenAPI ````yaml /openapi/openapi.yaml get /bots/{botId}/scheduling/availabilities openapi: 3.0.3 info: title: Annie API description: > ### Overview The Annie API is a (mostly) RESTful API. Typically, both POST bodies and responses are JSON-encoded. Note: The documenation is Work In Progress and is subject to change. ### Base URL The base URL for the Annie API is https://api.helloannie.com/. Examples in this document may abbreviate this to `/`. ### Versioning Routes are prefixed with a version number i.e. `v1`. The version will change when there is a non-backwards compatible or other significant change to the api. ### Authentication The Annie API supports two authentication methods API Keys and OAuth Access Tokens: #### API Keys API Keys are long-lived tokens that can be generated from the Developer Portal on your organization page. API keys are prefixed with `annie-sk-v2-` and can be used directly in the `Authorization` header. ``` curl -H "Authorization: Bearer annie-sk-xxxxx" https://api.helloannie.com/... ``` #### OAuth Tokens OAuth tokens are short-lived access tokens generated using the OAuth 2.0 Client Credentials flow (Machine-to-Machine). OAuth clients provide scoped permissions and are ideal for server-to-server integrations. **Creating an OAuth Client** OAuth clients can be created in the Developer Portal on your organization page. When creating a client, you'll receive: - `client_id`: Your OAuth client identifier - `client_secret`: Your OAuth client secret (store this securely) **Generating an OAuth Token** To generate an OAuth access token, make a POST request to the Annie OAuth token endpoint: **Endpoint:** `https://annie-external-api.us.auth0.com/oauth/token` **Example Request:** ```bash curl -X POST https://annie-external-api.us.auth0.com/oauth/token \ -H "Content-Type: application/json" \ -d '{ "grant_type": "client_credentials", "client_id": "your-client-id", "client_secret": "your-client-secret", "audience": "https://api.helloannie.com" }' ``` The `access_token` from the response should be used in the `Authorization` header when making requests to the Annie API: ``` curl -H "Authorization: Bearer eyJhbGciOiJSUzI..." https://api.helloannie.com/v1/... ``` ### API Response Structure The Annie API returns status codes consistent with standard HTTP conventions. Success and Error responses follow the below structure: ``` { "success": boolean "data": {} "message": string // optional } ``` ### Rate Limiting The Annie API enforces rate limits to ensure stability and fair usage. The default rate limit is **60 requests per minute** per organization. This limit is applied per endpoint pattern (e.g. `GET /v1/bots/:id`). When the rate limit is exceeded, the API responds with HTTP `429 Too Many Requests`. Response headers include: - `X-RateLimit-Limit`: The maximum number of requests allowed in the current window. - `X-RateLimit-Remaining`: The number of requests remaining in the current window. - `X-RateLimit-Reset`: The time at which the current rate limit window resets (in UTC epoch seconds). If you exceed the limit, the response will contain a `Retry-After` header indicating how many seconds to wait before retrying. ### Pagination The Annie API does not currently support pagination. All results are returned at once. version: v1 servers: - url: https://api.helloannie.com/v1 security: [] paths: /bots/{botId}/scheduling/availabilities: get: tags: - Scheduling summary: List scheduling availabilities description: >- Returns available appointment start and end times for a bot and appointment type.
