Setup Instructions

  1. Prepare Salesforce's end for Integration:
    • Open another browser tab and go to Salesforce website and log into your account.
    • On the left navigation menu, click on Apps, then click App Manager.
    • At the top right corner of the page, click the New Connected App button.
    • Fill out the fields in the Basic Information section.
    • In the API (Enable OAuth Settings) section, click the Enable OAuth Settings checkbox.
    • More fields will appear. In the Callback URL field, enter any valid URL that begins with https (it could even be, as we don't use this part).
    • In the Selected OAuth Scopes field, select the following permissions from the list and click Add arrow button:
      • Allow access to your unique identifier (openid)
      • Perform requests on your behalf at any time (refresh_token, offline_access)
    • You shouldn't need to fill out any further fields, and then click Save button.
    • You will be taken to a new page that lists info about your newly created app, including Consumer Key and Consumer Secret values. You will need to copy each of these values.
      • Salesforce gets tricky to navigate, so do yourself a favor and copy and paste these 2 values into a text editor for now, being sure to label each too. You'll save yourself some extra steps later on.
    • At the top middle of the page, click on the Manage button.
    • At the top middle of the next page, click the Edit Policies button.
    • Under the OAuth policies section, adjust the following settings:
      • In the Permitted Users field, be sure that it is set to All users may self-authorize.
      • In the IP Relaxation field, change the setting to Relaxed IP restrictions.
      • Click Save button at bottom of page.
    • If you copy and pasted the Consumer Key and Consumer Secret values in a text editor, you can skip these next couple steps:
      • To go back to your app to see these values, click on the App Manager navigation item (under Apps)
      • Find your app in the list. Then in the right column, click the down arrow, and then click View.
  2. Setup Integration on your site:
    • If you wish to use a config file for Salesforce credentials instead, please see Alternate Config File Setup documentation further below.
    • Go to the CRM section in Freeform Settings (Freeform > Settings > CRM)
    • Click the New CRM Integration at the top right.
    • Select Salesforce Lead from the Service Provider select dropdown.
    • Enter a name and handle for the integration.
    • Enter Salesforce credentials in the next 4 fields:
      • Paste the Salesforce Consumer Key value into the Client ID field in Freeform.
      • Paste the Salesforce Consumer Secret value into the Client Secret field in Freeform.
      • Enter your Salesforce account username/email address into the Username field in Freeform.
      • Enter your Salesforce account password into the Password field in Freeform.
    • Additional configuration options:
      • Assign Lead Owner? - Enabling this will make Salesforce assign a lead owner based on lead owner assignment rules in Salesforce.
      • Sandbox Mode - Enable this if your Salesforce account is in Sandbox mode.
      • Using custom URL? - Enable this if you connect to your Salesforce account with a custom company URL such as
    • At the top right corner of Freeform page, click Save button.
  3. Verify Authorization:
    • After the integration is saved, it'll return you to the list of CRM integrations.
    • Click into the newly created integration.
    • Confirm that there is green circle with Authorized in the middle of the page.
    • That's it! You can now use this integration inside Composer.

Alternate Config File Setup

  • The Salesforce Lead integration allows you the choice of entering your API keys and credentials via a config file instead if you wish. For more information about Freeform's config overrides, please see Freeform Config Overrides documentation. A brief overview is below:
    • Copy and paste the following code into a new file named freeform.php and place it into your Craft /config/ directory:

        return [
        	"salesforce_client_id"     => null,
        	"salesforce_client_secret" => null,
        	"salesforce_username"      => null,
        	"salesforce_password"      => null,
    • Replace the null value for salesforce_client_id with the Salesforce Consumer Key value.

    • Replace the null value for salesforce_client_secret with the Salesforce Consumer Secret value.

    • Replace the null value for salesforce_username with your Salesforce account username/email address.

    • Replace the null value for salesforce_password with your Salesforce account password.

    • Save the changes in the freeform.php file.

    • Your final file should look something like this:

        return [
        	"salesforce_client_id"     => "7SDf7GFDG6O76sd798FdG98s9897F9G7dSFDF9G7sd980G8dfG9FG_aSD650g8dsh7D98g79Fs98ds0788Ps",
        	"salesforce_client_secret" => "1234567890123456789",
        	"salesforce_username"      => "",
        	"salesforce_password"      => "yourSalesforcePassword",
