Error Handling

The SDK raises typed error classes for different failure scenarios, making it simple to handle specific error conditions in your application.

Error Classes

All API errors extend the base Felloh::Error class. You can rescue the base class or target specific error types.

Error Class	Status Code	Description
`Felloh::AuthenticationError`	401	Invalid API credentials or expired token
`Felloh::ForbiddenError`	403	Insufficient permissions for the requested action
`Felloh::NotFoundError`	404	The requested resource does not exist
`Felloh::ValidationError`	422	Request body failed validation — check `errors` for field-level details
`Felloh::RateLimitError`	429	API rate limit exceeded
`Felloh::ServerError`	5xx	Server error — the SDK automatically retries these
`Felloh::NetworkError`	—	Network failure (timeout, DNS, connection refused) — also retried automatically

The Error Object

Every error raised by the SDK includes structured data about the failure.

Properties

Name

Name
meta
Type
Hash
Description
Response metadata including request_id — useful for debugging with Felloh support.

Error Handling

begin
  client.bookings.get("non-existent-id")
rescue Felloh::NotFoundError => e
  puts "Booking not found"
rescue Felloh::ValidationError => e
  # Inspect field-level validation errors
  e.errors.each do |error|
    puts "#{error['title']}: #{error['message']}"
  end
rescue Felloh::Error => e
  puts e.status_code  # HTTP status code
  puts e.errors       # API error details
  puts e.meta         # Includes request_id
end

Automatic Retries

The SDK automatically retries requests that fail with a 5xx server error or a network error. Retries use exponential backoff with a maximum of max_retries attempts (default: 2).

You can configure this when creating the client:

Configuring Retries

client = Felloh::Client.new(
  public_key: "your-public-key",
  private_key: "your-private-key",
  max_retries: 3,  # retry up to 3 times
  timeout: 15,     # 15 second timeout per request
)
