Installation

To use this gem during the beta, install directly from GitHub with Bundler by adding the following to your application's Gemfile:

gem "increase", git: "https://github.com/Increase/increase-ruby", branch: "main"

To fetch an initial copy of the gem:

bundle install

To update the version used by your application when updates are pushed to GitHub:

bundle update increase

Usage

require "increase"

increase = Increase::Client.new(
  api_key: "My API Key", # defaults to ENV["INCREASE_API_KEY"]
  environment: "sandbox" # defaults to "production"
)

account = increase.accounts.create(
  name: "New Account!",
  entity_id: "entity_n8y8tnk2p9339ti393yi",
  program_id: "program_i2v2os4mwza1oetokh9i"
)

puts(account.id)

Errors

When the library is unable to connect to the API, or if the API returns a non-success status code (i.e., 4xx or 5xx response), a subclass of Increase::HTTP::Error will be thrown:

begin
  account = increase.accounts.create
rescue Increase::HTTP::Error => e
  puts(e.code) # 400
end

Error codes are as followed:

Cause	Error Type
HTTP 400	BadRequestError
HTTP 401	AuthenticationError
HTTP 403	PermissionDeniedError
HTTP 404	NotFoundError
HTTP 409	ConflictError
HTTP 422	UnprocessableEntityError
HTTP 429	RateLimitError
HTTP >=500	InternalServerError
Other HTTP error	APIStatusError
Timeout	APITimeoutError
Network error	APIConnectionError

Retries

Certain errors will be automatically retried 2 times by default, with a short exponential backoff. Connection errors (for example, due to a network connectivity problem), 408 Request Timeout, 409 Conflict, 429 Rate Limit, >=500 Internal errors, and timeouts will all be retried by default.

You can use the max_retries option to configure or disable this:

# Configure the default for all requests:
increase = Increase::Client.new(
  max_retries: 0 # default is 2
)

# Or, configure per-request:
increase.accounts.create(
  name: "New Account!",
  entity_id: "entity_n8y8tnk2p9339ti393yi",
  program_id: "program_i2v2os4mwza1oetokh9i",
  max_retries: 5
)

Timeouts

By default, requests will time out after 60 seconds. Timeouts are applied separately to the initial connection and the overall request time, so in some cases a request could wait 2*timeout seconds before it fails.

You can use the timeout option to configure or disable this:

# Configure the default for all requests:
increase = Increase::Client.new(
  timeout: nil # default is 60
)

# Or, configure per-request:
increase.accounts.create(
  name: "New Account!",
  entity_id: "entity_n8y8tnk2p9339ti393yi",
  program_id: "program_i2v2os4mwza1oetokh9i",
  timeout: 5
)

Versioning

This package follows SemVer conventions. As the library is in initial development and has a major version of 0, APIs may change at any time.

Requirements

Ruby 3.0 or higher.
