README

Forcex

Build Status Hex.pm Version Coverage Status

Elixir library for interacting with the Force.com REST API.

Usage

Add Forcex to your dependency list

  defp deps do
    [ {:forcex, "~> 0.4"}
    ]
  end

At compile time Forcex will query the Force.com REST API and generate modules for all the SObjects you have configured and permission to see.

If you see a warning like

23:37:02.057 [warn]  Cannot log into SFDC API. Please ensure you have Forcex properly configured.
Got error code 400 and message %{"error" => "invalid_client_id", "error_description" => "client identifier invalid"}

You will need to configure Forcex, as noted below, and then explicitly recompile Forcex

$ mix deps.clean forcex
$ mix deps.compile forcex

You can have Forcex generate modules at compile time using the accompanying Mix task.

$ mix compile.forcex

This can also be invoked automatically by adding Forcex to your project's compilers in mix.exs

compilers: [:forcex] ++ Mix.compilers,

Bulk API Usage

Forcex has an example Bulk API query job controller. Here's roughly how that can work.

client = Forcex.Bulk.Client.login
[
  "Account",
  "Campaign",
  "Contact",
  "Lead",
  "Opportunity",
  "OpportunityLineItem",
]
|> Enum.map(fn sobject -> {sobject, ["select Id, Name from #{sobject}"]} end)
|> Enum.map(fn {sobject, queries} ->
Forcex.Bulk.JobController.start_link({:query, sobject, queries, client}) end)

Configuration

The Forcex.Client is configured to read login information either from application configuration:


config :forcex, Forcex.Client,
  username: "[email protected]",
  password: "my_super_secret_password",
  security_token: "EMAILED_FROM_SALESFORCE",
  client_id: "CONNECTED_APP_OAUTH_CLIENT_ID",
  client_secret: "CONNECTED_APP_OAUTH_CLIENT_SECRET"

or these environment variables:

  • SALESFORCE_USERNAME
  • SALESFORCE_PASSWORD
  • SALESFORCE_SECURITY_TOKEN
  • SALESFORCE_CLIENT_ID
  • SALESFORCE_CLIENT_SECRET

HTTPoison request-specific options may also be configured:

config :forcex, :request_options,
  timeout: 20000,
  recv_timeout: :infinity

For steps on how to create a Connected App with OAuth keys and secrets, please see the Force.com REST API section on Connected Apps.

Currently, to be fully functional, the Forcex.Client must both login and locate_services.

Pagination of results is entirely manual at the moment.

client = Forcex.Client.login |> Forcex.Client.locate_services

first_page = Forcex.query("select Id, Name from Account order by CreatedDate desc", client)

second_page = first_page |> Map.get(:nextRecordsUrl) |> Forcex.get(client)

Further Configuration

Forcex allows additional configuration of API endpoint and API version via the %Forcex.Client{} struct. You may also use this mechanism if you have a grant_type other than password.

This example shows how to use both an older API version and the SalesForce sandbox API.

Forcex.Client.default_config
|> Forcex.Client.login(%Forcex.Client{endpoint: "https://test.salesforce.com", api_version: "34.0"})

Testing

Make sure dependencies are installed

mix deps.get

Tests can be run with

mix test

Tests can be run automatically when files change with

mix test.watch --stale

Tests mock the api calls to the Salesforce API using Mox to set expectations on Forcex.Api.MockHttp.raw_request. To know what to put in a mock response just run the client in iex and look for the debug logging response from http.ex. Make sure to scrub any responses for sensitive data before including them in a commit.

Example assuming environment variables are in place with login info

% iex -S mix
iex(1)> client = Forcex.Client.login |> Forcex.Client.locate_services
14:40:27.858 file=forcex/lib/forcex/api/http.ex line=19 [debug] Elixir.Forcex.Api.Http.raw_request response=%{access_token: "redacted",...
14:40:28.222 file=forcex/lib/forcex/api/http.ex line=19 [debug] Elixir.Forcex.Api.Http.raw_request response=%{process: "/services/data/v43.0/process", search...
iex(2)> Forcex.query("select Id, Name from Account order by CreatedDate desc", client)
14:43:05.896 file=forcex/lib/forcex/api/http.ex line=19 [debug] Elixir.Forcex.Api.Http.raw_request response=%{done: false, nextRecordsUrl: "/services/data/v4

Just take the data after response= and throw it in a Mox expectation. See existing tests for full examples

response = %{access_token: "redacted"}
Forcex.Api.MockHttp
|> expect(:raw_request, fn(:get, ^expected_url, _, ^auth_header, _) -> response end)
