A lightweight, flexible library for desk.com APIv2, it supports basic auth and OAuth as authentication methods and is written to be auto discoverable.
DeskApi takes the capabilities of the Desk.com API and wraps them up in a Ruby
client so that it’s easy-as-pie to get working with your support site’s API.
Desk.com publishes a change log monthly, which you can keep up with at
dev.desk.com/API/changelog.
We do our best to keep DeskApi, but please don’t hesitate to open an
issue or send a
pull request
if you find a bug or would like to new functionality added.
Easy!
gem install desk_api
The Desk.com API allows you to access data using two authentication mechanisms:
Whatever option or method you choose, please make sure to never put your
credentials in your source code. This makes them available to everyone
with read access to your source, it makes your code harder to maintain and
is just overall a bad idea. There are many alternatives, including configuration
files, environmental variables, …
DeskApi
is automatically configured if you choose to use environmental
variables. There are 8 possible variables but you don’t have to set all of them.
Based on the authentication mechanism you prefer you’ll only have to specify:
export [email protected]
export DESK_PASSWORD=somepassword
export DESK_CONSUMER_KEY=CONSUMER_KEY
export DESK_CONSUMER_SECRET=CONSUMER_SECRET
export DESK_TOKEN=TOKEN
export DESK_TOKEN_SECRET=TOKEN_SECRET
export DESK_SUBDOMAIN=devel
export DESK_ENDPOINT=https://devel.desk.com
Configure DeskApi
itself to send/receive requests by calling the configure
method to set up your authentication credentials:
DeskApi.configure do |config|
# basic authentication
config.username = '[email protected]'
config.password = 'somepassword'
# oauth configuration
config.token = 'TOKEN'
config.token_secret = 'TOKEN_SECRET'
config.consumer_key = 'CONSUMER_KEY'
config.consumer_secret = 'CONSUMER_SECRET'
config.endpoint = 'https://devel.desk.com'
end
DeskApi.get '/api/v2/topics'
DeskApi.post '/api/v2/topics', name: 'My new Topic', allow_questions: true
DeskApi.patch '/api/v2/topics/1', name: 'Changed the Topic Name'
DeskApi.delete '/api/v2/topics/1'
Initialize a new DeskApi::Client
to send/receive requests
This example shows you how to initialize a new client and the four main request
methods supported by the Desk.com API (GET
, POST
, PATCH
and DELETE
).
# basic authentication
client = DeskApi::Client.new username: '[email protected]', password: 'somepassword', endpoint: 'https://devel.desk.com'
# oauth configuration
client = DeskApi::Client.new({
token: 'TOKEN',
token_secret: 'TOKEN_SECRET',
consumer_key: 'CONSUMER_KEY',
consumer_secret: 'CONSUMER_SECRET',
endpoint: 'https://devel.desk.com'
})
response = client.get '/api/v2/topics'
response = client.post '/api/v2/topics', name: 'My new Topic', allow_questions: true
response = client.patch '/api/v2/topics/1', name: 'Changed the Topic Name'
response = client.delete '/api/v2/topics/1'
Resources are automatically discovered by the DeskApi. When requesting a
resource from DeskAPI, the client sends the request and returns a
DeskApi::Resource
. If the client receives an error back from the API a
DeskApi::Error
is raised.
One of the most important features; we support creating, updating and deleting
resources but not all resources can be deleted or updated or created, if that’s
the case for the resource you’re trying to update, it’ll throw a
DeskApi::Error::MethodNotAllowed
error. For ease of use and because we wanted
to build as less business logic into the wrapper as possible, all of the methods
are defined on each DeskApi::Resource
and will be sent to desk.com. However
the API might respond with an error if you do things that aren’t supported.
# let's create an article
new_article = DeskApi.articles.create({
subject: 'Some Subject',
body: 'Some Body',
_links: {
topic: DeskApi.topics.first.get_self
}
})
# as you can see here a `Resource' always includes a method `.get_self'
# which will return the link object to build relationships
# updating the article
updated_article = new_article.update subject: 'Updated Subject'
# deleting the article
if updated_article.delete == true
# article has been deleted
end
# ATTENTION: Cases can not be deleted!
begin
DeskApi.cases.first.delete
rescue DeskApi::Error::MethodNotAllowed => e
# too bad
end
As you have seen in prior examples for each field on the resource we create a
getter and setter.
customer = DeskApi.customers.find(1)
puts customer.first_name
puts customer.last_name
puts customer.title
# for updates you can either use the setter or a hash
customer.first_name = 'John'
customer.last_name = 'Doe'
updated_customer = customer.update title: 'Master of the Universe'
# users are not updatable
begin
user = DeskApi.users.first
user.update name: 'Not updatable'
rescue DeskApi::Error::MethodNotAllowed
# too bad
end
The method by_url
can be called on the client, for backwards compatibility we
haven’t yet removed it from the DeskApi::Resource
but it will be removed once
we release v1 of this client. by_url
will return a lazy loaded instance of the
resource.
first_reply = DeskApi.by_url '/api/v2/cases/1/replies/1'
Since the update to v0.5 of the API wrapper the find
method can now be called
on all DeskApi::Resource
instances. Gotcha: It will rebuild the base path
based on the resource/collection it is called on. So if you call it on the cases
collection DeskApi.cases.find 1
the path will look like this:
/api/v2/cases/:id
.
Method | Path |
---|---|
DeskApi.cases.find(1) |
/api/v2/cases/1 |
DeskApi.cases.entries.find(1) |
/api/v2/cases/1 |
DeskApi.cases.search(subject: 'Test').find(1) |
/api/v2/cases/1 |
DeskApi.cases.search(subject: 'Test').entries.find(1) |
/api/v2/cases/1 |
DeskApi.cases.entries.first.replies.find(1) |
/api/v2/cases/1/replies/1 |
DeskApi.cases.entries.first.replies.entries.first.find(1) |
/api/v2/cases/1/replies/1 |
As mentioned above you can also navigate between resources and pages of
collections.
cases = DeskApi.cases
cases.entries.each do |my_case|
# do something with the case
end
# now move on to the next page
next_page = cases.next
next_page.entries.each do |my_case|
# do something with the case
end
# go back to the previous page
previous_page = next_page.previous
# or go to the last page
last_page = previous_page.last
# or go to the first page
first_page = last_page.first
all
and each_page
As a recent addition we made it even easier to navigate through all the pages.
DeskApi.cases.all do |current_case, current_page_number|
# do something with the case
end
DeskApi.cases.each_page do |current_page, current_page_number|
# do something with the current page
end
Both methods use the max per_page
for the API endpoint for that particular
resource.
Some lists allow for additional params like cases.
This allows you to filter the cases endpoint by using a company_id
,
customer_id
or filter_id
list param.
# fetch cases for the company with id 1
companys_cases = DeskApi.cases(company_id: 1)
# fetch cases for the customer with id 1
customers_cases = DeskApi.cases(customer_id: 1)
# fetch cases for the filter with id 1
filters_cases = DeskApi.cases(filter_id: 1)
There is a maximum page
limit on some Desk.com API endpoints. As of right now
(May 2014) the limit is 500 for all endpoints that are limited, but please
consult the #list documentation for each resource:
To work around page limits, you can specify sort_field
and sort_direction
# fetch cases sorted by updated_at direction desc
sorted_cases = DeskApi.cases(sort_field: :updated_at, sort_direction: :desc)
Once a DeskApi::Resource
has loaded, its
linked resources
can be retrieved by calling the linked resource as a method of the
DeskApi::Resource
, e.g.,
# Get a ticket
ticket = DeskApi.cases.entries.first
# Get the ticket's assigned_user from the ticket
assigned_user = ticket.assigned_user
# Get the customer from the ticket
customer = ticket.customer
# Get the customer's company from the customer.
company = customer.company
# Getting the name of the user who sent the first outbound reply on a ticket
user_name = DeskApi.
cases.
entries.
select { |my_case| my_case.type == 'email' }.
first.
replies.
entries.select { |reply| reply.direction == 'out' }.
first.
sent_by.
name
Resources are lazy loaded. This means that requests are only sent when you
request data from the resource. This helps a lot with flying under the Desk.com
API rate limit. E.g.,
DeskApi.cases.page(10).per_page(50).entries.each do |my_case|
# in this method chain, no HTTP request is fired until `.entries'
end
# however if you request the current page number and the resource is not loaded
# it'll send a request
DeskApi.cases.page == 1
Some endpoints support embedding
related resources. E.g., when getting a list of cases from /api/v2/cases
you
can embed the customer on each case by adding embed=
to the query
string: /api/v2/cases?embed=customer
The client supports this: tickets_and_customers = DeskApi.cases.embed(:customer)
Taking advantage of .embed
is a great way to be conscious of the rate limit
and minimize necessary HTTP requests.
Not using embedded resources
tickets = DeskApi.cases.per_page(100).entries # HTTP request
tickets.each do |ticket|
puts ticket.customer.first_name # HTTP request (100 iterations)
end
# Total Requests: 101
Using embedded resources
tickets = DeskApi.cases.per_page(100).embed(:customer).entries # HTTP request
tickets.each do |ticket|
puts ticket.customer.first_name # No HTTP Request, customer is embedded
end
# Total Requests: 1
Using embedded resources in find
my_case = DeskApi.cases.find(1, embed: :customer)
# OR
my_case = DeskApi.cases.find(1, embed: [:customer, :assigned_user, :assigned_group, :message])
customer = my_case.customer
assigned_user = my_case.assigned_user
assigned_group = my_case.assigned_group
Attachment resources can be downloaded directly, a Tempfile
is returned that can either be read or moved to the final location.
ticket = DeskApi.cases.find(123)
attachment = ticket.attachments.entries.first
file = attachment.download
# Read the file
content = file.read
# Save the file
File.open('/path/to/my/storage', 'w') do |f|
f.write(content)
end
Sometimes the API is going to return errors, eg. Validation Error. In these
cases we wrap the API error into a DeskApi::Error
. Here are the common errors:
DeskApi::Error::BadRequest #=> 400 Status
DeskApi::Error::Unauthorized #=> 401 Status
DeskApi::Error::Forbidden #=> 403 Status
DeskApi::Error::NotFound #=> 404 Status
DeskApi::Error::MethodNotAllowed #=> 405 Status
DeskApi::Error::NotAcceptable #=> 406 Status
DeskApi::Error::Conflict #=> 409 Status
DeskApi::Error::UnsupportedMediaType #=> 415 Status
DeskApi::Error::UnprocessableEntity #=> 422 Status
DeskApi::Error::TooManyRequests #=> 429 Status

desk.com API errors and
their respective meanings.
