Change of the Site URL

Sites creates public web applications and websites that run natively on Force.com, but under your own domain. During the implementation the consultant create a site, but here you can find the instructions if you want to customize it, or modify it if the company name is changed. 

Change of Sites

Sites extends the reach of the applications to external audiences, like candidates. Besides, your site visitors don't need to authenticate to view your pages, such as the application form.

1. Preparation

2. Salesforce

Submit the request for this change by creating a Salesforce case. The deployment will be planned together with Salesforce.

3. After the Change
a. Go to the Connexys Setup, Application Settings, All settings, General and fill in the new Site URL at “Salesforce domain name”
b. Go in the Salesforce Setup and look for “Remote Site Settings”, create a New Remote Site with the new Site URL.
c. From the created overview (step 1), edit the hard coded URL with the new (sub)domain.

Change of My Domain

The same steps applies for the The My Domain (except step 3.a). The My Domain Salesforce feature makes it possible to add a subdomain to your Salesforce org URL. If you want to change the Subdomain, you should read this Salesforce article for more background information. For example you can change a subdomain into https://somethingcool.my.salesforce.com instead of https://na30.salesforce.com. Notice that this URL is for internal use, so for the Connexys application (see the image below).

Note: If you change the domain name, you need to be aware that indexed candidates need to re-indexed or the links (buttons) refer to the old domain and will not work.
