Hello everyone. Today, we will discuss the steps to change public resource URL http to https in ACS. After logging into campaign, we need to navigate to resources, then templates, and finally to delivery templates. In here, we need to choose the template for which we want to make the change. After opening the template, click on the content to open the file. Then from the dropdown, click on HTML. Once the HTML file opens up, look for the image you are in it and change it from HTTP to HTTPS, as shown on screen and save and close the template. So in this way, we can successfully change public resource URL http to https in ACS. Thank you. -
