# Transitioning from RForcecom

#### Steven M. Mortimer

#### 2021-07-03

While writing the {salesforcer} package we were keenly aware that many folks were already using the {RForcecom} package to connect to Salesforce. In order to foster adoption and switching between the packages {salesforcer} replicates the functionality of many {RForcecom} functions so that you will only need to swap out `library(RForcecom)` for `library(salesforcer)` and still have production scripts perform as expected.

## RForcecom Removed from CRAN

As of June 9, 2021, the {RForcecom} package was removed from CRAN. You can still use it by installing from the archive, but we strongly recommend using {salesforcer} instead. The existing functionality in {RForcecom} has been further optimized within {salesforcer} and new functionality has been added too.

## Salesforce Requires MFA Which Prevents RForcecom Basic Auth Log in

Basic authentication (password and security token) will no longer work since Salesforce announced that all customers will be migrated to MFA beginning February 1st, 2022 (link). As a result, the basic authentication routine used {RForcecom} and the legacy, compatibility method written into {salesforcer} will no longer work. Please migrate to {salesforcer} and use `sf_auth()` to generate an OAuth 2.0 token. The examples below will no longer work.

## Authentication

{salesforcer} supports OAuth 2.0 authentication which is preferred, but for backward compatibility provides the username-password authentication routine implemented by {RForcecom}. Here is an example running the function from each of the packages side-by-side and producing the same result.

First, authenticate and load any required packages for your analysis.

    library(salesforcer)
    sf_auth()

    # Beginning February 1, 2022, basic authentication will no longer work. You must
    # log in to Salesforce using MFA (generating an OAuth 2.0 token typically from
    # the browser).

    # the RForcecom way
    # RForcecom::rforcecom.login(username, paste0(password, security_token),
    #                            apiVersion=getOption("salesforcer.api_version"))
    # replicated in salesforcer package
    session <- salesforcer::rforcecom.login(username,
                                             paste0(password, security_token),
                                             apiVersion = getOption("salesforcer.api_version"))
    session['sessionID'] <- "{MASKED}"
    session

Note that we must set the API version here because calls to session will not create a new `sessionId` and then we are stuck with version 35.0 (the default from `RForcecom::rforcecom.login()`). Some functions in {salesforcer} implement API calls that are only available after version 35.0.

## CRUD Operations

“CRUD” operations (Create, Retrieve, Update, Delete) in the {RForcecom} package only operate on one record at a time. One benefit to using the {salesforcer} package is that these operations will accept a named vector (one record) or an entire `data.frame` or `tbl_df` of records to churn through. However, rest assured that the replicated functions behave exactly the same way if you are hesitant to making the switch.

Here is an example showing the reduction in code of using {salesforcer} if you would like to create multiple records.

    n <- 2
    new_contacts <- tibble(FirstName = rep("Test", n),
                           LastName = paste0("Contact-Create-", 1:n))

    # the RForcecom way (requires a loop)
    # rforcecom_results <- NULL
    # for(i in 1:nrow(new_contacts)){
    #   temp <- RForcecom::rforcecom.create(session,
    #                                       objectName = "Contact",
    #                                       fields = unlist(slice(new_contacts,i)))
    #   rforcecom_results <- bind_rows(rforcecom_results, temp)
    # }

    # the better way in salesforcer to do multiple records
    salesforcer_results <- sf_create(new_contacts, object_name="Contact")
    salesforcer_results
    #> # A tibble: 2 × 2
    #>   id                 success
    #>   <chr>              <lgl>
    #> 1 003Kg000002Ac5rIAC TRUE
    #> 2 003Kg000002Ac5sIAC TRUE

## Query

{salesforcer} also has better printing and type-casting when returning query result thanks to features of the {readr} package.

    this_soql <- "SELECT Id, Email FROM Contact LIMIT 5"

    # the RForcecom way
    # RForcecom::rforcecom.query(session, soqlQuery = this_soql)

    # the better way in salesforcer to query
    salesforcer_results <- sf_query(this_soql)
    salesforcer_results
    #> # A tibble: 5 × 1
    #>   Id
    #>   <chr>
    #> 1 003Kg000002AaGiIAK
    #> 2 003Kg000002AaGjIAK
    #> 3 003Kg000002Ac5rIAC
    #> 4 003Kg000002Ac5sIAC
    #> 5 003Kg000002AaJ7IAK

## Describe

The {RForcecom} package has the function `rforcecom.getObjectDescription()` which returns a `data.frame` with one row per field on an object. The same function in {salesforcer} is named `sf_describe_object_fields()` and also has better printing and datatype casting by using tibbles.

    # the RForcecom way
    # RForcecom::rforcecom.getObjectDescription(session, objectName='Account')

    # the better way in salesforcer to get object fields
    result2 <- salesforcer::sf_describe_object_fields('Account')
    result2
    #> # A tibble: 68 × 39
    #>   aggregatable aiPredictionField autoNumber byteLength calculated caseSensitive
    #>   <chr>        <chr>             <chr>      <chr>      <chr>      <chr>
    #> 1 true         false             false      18         false      false
    #> 2 false        false             false      0          false      false
    #> 3 true         false             false      18         false      false
    #> 4 true         false             false      765        false      false
    #> 5 true         false             false      765        false      false
