• Next, add a Loop element onto the canvas. For this element, enter the following details:
  1. Enter Loop through each SharinPix Image as the label
  2. In the Select Collection Variable section, choose the Get SharinPix Image records created earlier.

Next add an Assignment element inside the loop element, to assign the each SharinPix Image Ids to the ImageIdsList variable, as we will need a list of images Ids as a parameter for the ShareAutomation action, to generate the public URL for an album with those images. For this element, enter the following details:

1. Enter Assign SharinPix Image Public Ids as the label
2. In the Select Variable Values section, enter ImageIdsList as the Variable, Add as the operator and for the value, choose Current Item from Loop and then Image Public Id (Example: {!Loop_through_each_SharinPix_Image.sharinpix__ImagePublicId__c} ).

• On the Action modal for sharinpix__ShareAutomation, populate the fields as indicated below:
  • Label: Generate an album public url with Specified Images
  • Description: Enter a description (optional)
  • Record ID: {!recordId}
    • Note: This is a mandatory field and refers to the current Account ID.
  • Custom Permission Id or Name: PermissionName (Create a SharinPix Permission with the permissions/abilities needed for the users using this public album) 
    • Note: This permission will be provided to the public album. If upload, edit or delete permissions are present, the viewers of the shared URL will be able to make changes to your images that will reflect on your Salesforce.
  • List of Image Ids: ImageIdsList (variable being populated with the SharinPix Image Ids)
    • Note: If no value is provided here, all the images on the album will be available on the shared album.

Lastly, Add an Update Records element onto the canvas. For this element, enter the following details:

1. Enter Update Account field with the URL Generated as the label
2. In the Set Field Values for the Account Record section, enter Shared_Album_URL__c as the Field, and choose Text from Generate_an_album_public_url_with_Specified_Images (Example: {!Generate_an_album_public_url_with_Specified_Images}).

To test the Flow:

• Go on an Account record and upload some images to its corresponding SharinPix album with one or 2 images with the tag 'Broken'.

• Then, change the Status of the Account to 'Investigation In Progress'.

• On the Account record, the url generated through the flow should be available on the field 'Shared Album URL'.

• Open the URL on a browser as shown below, this URL can be shared to clients via email.
