title: 100Hires Template Placeholders API
version: 2.0.0
description: '## Introduction to the 100Hires ATS API
The 100Hires ATS API (v2) helps you automate recruiting workflows end-to-end: candidates, applications, jobs, forms, notes, and partner-company operations. All endpoints return JSON and use bearer authentication. ## OpenAPI Spec
The 100Hires ATS API follows the OpenAPI 3.x specification. Download the machine-readable spec for use in MCP servers, Cursor, Claude Code, or any OpenAPI tooling:
`GET https://api.100hires.com/v2/openapi.json`
## Authentication
Send API token in the `Authorization` header for every request:
`Authorization: Bearer `
Each API key is tied to a specific **user + company** pair. If the same user belongs to multiple companies, they need a separate key for each company. All actions performed through the API are attributed to the key owner. You can generate or view your API key at https://app.100hires.com/settings/integrations
### API Key Verification
API keys for **unverified companies** are created in a disabled state and will return `401 Unauthorized` until the company passes verification. Once your company is verified, API keys start working automatically — no action required. If your key returns `401` and you believe your company should be verified, contact **support@100hires.com**. ## Rate Limits
API keys that are not yet approved, such as keys created during the free trial, are subject to a hard rate limit of **1,000 requests per 10 minutes** per company. All API keys and MCP connections of a company share this limit. If your company is managed by a partner, it shares the partner''s limit. Personal API keys are approved automatically when the company starts a paid subscription. Requests over the limit receive a `429 Too Many Requests` response. ### Rate limit headers
Unapproved keys include these headers on every response:
| Header | Description |
|--------|-------------|
| `X-RateLimit-Limit` | Maximum requests allowed in the current window |
| `X-RateLimit-Remaining` | Requests remaining in the current window |
| `X-RateLimit-Reset` | Unix timestamp (seconds) when the window resets |
### Handling 429 responses
When you receive a `429` response, wait until `X-RateLimit-Reset` before retrying. Do not retry immediately — repeated 429s may extend the cooldown. To remove rate limits for your integration, contact **support@100hires.com** with your use case. ## Content-Type
All request bodies **must** use `Content-Type: application/json`. Sending `application/x-www-form-urlencoded`, `multipart/form-data`, or any other content type
will result in a `415 Unsupported Media Type` error. ## Responses and Errors
Standard HTTP status codes are used (`2xx`, `4xx`, `5xx`). All error responses are wrapped in an `error` object containing `name`, `message`, `code`, and `status`. Validation errors additionally include field-level details in `error.validation_errors`. See the Error handling section below for the full format and status table. ## Pagination
List endpoints use `page` (1-based) and `size` (1-100, default 20). Paginated responses follow:
`{ "": [...], "pagination": { "page_size", "page_count", "page", "total_count" } }`. ## Lists
List routes are optimized for synchronization and operational dashboards. Most list endpoints support tenant scoping through optional `company_id` (when allowed by API key context). ## Confidential Data
Some candidate profile values can be masked by account-level pricing/access rules. Integrations should not assume all profile fields are always fully visible. ## Customizing the Response
Use endpoint filters (`status`, `job_id`, timestamps, taxonomy IDs, etc.) to minimize payload size and improve sync efficiency. Build incremental sync flows around timestamp filters where available. ## Supported File Formats
File uploads use base64 payloads with metadata:
`data`, `file_name`, `mime_type` (and optionally `size`). This format is used for candidate files, resumes, attachments, and logos.'
