Ruby interface to Tide's bank RESTful API.

Table of contents


Add this line to your application's Gemfile:

gem 'tide-api'

And then execute:

$ bundle

Or install it yourself as:

$ gem install tide-api



Tide uses Access Tokens to allow access to the API via OAuth 2. Tide uses Access Tokens to allow access to the API via OAuth 2. You can obtain an OAuth 2 Access Token by navigating to the below url, either in the web application or through an in-app browser window:


Parameter Type Description
redirect_uri string Fully qualified URL to which Authorisation Grants will be delivered to. Grants will be delivered only on successful authorisation by resource owner.
client_id string Unique identifier for the requester.

Once the page loads, the user needs to enter the unique email address, which is registered on their Tide account.

Obtaining an Authorization Grant Code

Use the bundled minimalistic AuthServer to automate the process above:

require 'tide/api'
require 'tide/api/auth_server'

server = Tide::API::AuthServer.new
auth_grant_code = server.run

Authorisation Grants can only be used once off by the client, once used they are expired and cannot be used to issue new Access Tokens.

Exchanging an Authorisation Grant for an Access Token

Exchange the authorisation grant code with the method fetch_tokens:

client = Tide::API::Client.new
tokens = client.fetch_tokens(auth_grant_code)

# Tokens contains an access token and a refresh token

The method fetch_tokens will configure the client behind the scenes to make authenticated requests.

Fetching Companies

This method retrieves a collection of companies with the user. The user is determined from authorization header.

companies = client.fetch_companies

Fetching Accounts

This method retrieves a collection of company accounts associated with the user. The user is determined from authorization header.

accounts = client.fetch_accounts(companies.first.id)

Fetching Transactions

This method retrieves a collection of an account's transactions:

transactions = client.fetch_transactions(accounts.first.id)
