Reckon API Documentation

Authentication

All API requests require authentication using an API key passed in the X-API-Key header.

API Key Types

Reckon provides two types of API keys: public (client-side) and secret (server-side). When inputting your key, you must apply prefix so the system knows what type you're using:

pk_ - Public Keys

Example: X-API-Key: pk_1234567890abcdef

Used for client-side operations

Rate limiting (dual limiting system):

10 requests per key, per IP address, per minute

60 requests per key, per minute

Whichever is more restrictive applies

sk_ - Secret Keys

Example: X-API-Key: sk_1234567890abcdef

Used for server-side operations

Must be kept secure and never exposed to clients

Rate limiting:

500 requests per key, per minute

Security Best Practices

Keys can be created and managed in the Reckon app

Use public keys for client-facing use cases, like browser and mobile applications

Use secret keys for back-end functions, like running automated jobs or server-to-server integrations

Rate Limits

All endpoints are subject to rate limiting based on your API key type:

Response Headers

Rate limit information is included in response headers:

X-RateLimit-Limit: Total requests allowed per minute

X-RateLimit-Remaining: Requests remaining in current window

X-RateLimit-Reset: Unix timestamp for next window reset

Error Handling

When rate limits are exceeded, you'll receive a 429 Too Many Requests response with a Retry-After header.
