Limelight API
The Limelight API allows you to programmatically access and manage your Limelight data.
Authentication​
All API requests require a valid API key. Include your API key in the Authorization header:
Authorization: Bearer llt_live_your_api_key_here
You can generate and manage your API keys from Settings > API Keys in the Limelight dashboard.
Rate Limiting​
API requests are rate limited per API key. The default limit is 60 requests per minute.
Rate limit headers are included in all authenticated responses:
| Header | Description |
|---|---|
X-RateLimit-Limit | Maximum requests allowed per minute |
X-RateLimit-Remaining | Requests remaining in current window |
X-RateLimit-Reset | Unix timestamp when the window resets |
When the rate limit is exceeded, the API returns a 429 Too Many Requests response with a Retry-After header indicating how many seconds to wait before retrying.
Data Handling & Privacy​
Signal Lead endpoints return personally identifiable information (PII) including names, job titles, LinkedIn profile URLs, and company details. API consumers must:
- Store PII in encrypted-at-rest datastores and transmit only over TLS.
- Implement access controls limiting PII visibility to authorized personnel.
- Honor data-deletion requests and retention policies applicable to your jurisdiction (e.g. GDPR, CCPA).
- Never use PII for purposes beyond the scope authorized by your Limelight subscription.
Fields classified as PII are annotated with x-pii: true in the schema.
Versioning & Breaking Changes​
This API follows additive-only evolution: new fields may be added to response objects at any time. Clients should ignore unknown fields.
When fields are removed or renamed, they are first marked deprecated for at least one release cycle before removal. Deprecated fields still appear in responses but may return null.
