Set Up the Connected App for Salesforce Service Cloud

Provide Point of Sale access to a Salesforce Connected App using whichever Salesforce APIs can be invoked for Clienteling purposes.

Point of Sale also needs credentials to be able to login to the Salesforce portal in dev or testing to explore how merchant uses Salesforce objects.

• URL: Salesforce instance IRL
• Username
• Password
• Client_id of the Connected App
• Client_secret of the Connected App

Refer to POS Access List - URLs and IP Addresses for a list of URLs and IP addresses to be allowlist. This is to enable the necessary communication.

Note Connected apps creation is restricted as of Spring ‘26. You can continue to use existing connected apps during and after Spring ‘26. However, we recommend using external client apps instead. If you must continue creating connected apps, contact Salesforce Support.

See New connected apps can no longer be created in Spring ‘26 for more details.
