If you're looking to automatically gift loyalty points to new POS customers using Marketing Automation, here’s a clean path you can follow:

Smart Setup Without Custom Code

1. Enable the Loyalty Module
   • Go to Sales → Configuration → Settings → check Loyalty & Gift Cards, then save.
   • In POS → Configuration → Loyalty Programs, create a rule that grants X points when a purchase is made.
2. Detect “New Customer” in Automation
   • Use Odoo’s Marketing Automation app.
   • Create a trigger: When a new contact is created, filter these to only those with a POS order (or using similar criteria).
3. Issue Points via Server Action
   • Add an action: Click Loyalty, choosing “Add Points”.
   • Target the loyalty card linked to the new contact and specify points.
4. Confirmation Email (Optional)
   • If desired, include an automated email or chatter message to welcome the customer and confirm the points.

Why It Works

• Odoo handles loyalty operations through its built-in loyalty engine—so no need for heavy customization.
• Marketing Automation lets you combine triggers (new customer) with loyalty actions smoothly.
• You can later refine this: target only customers from a specific POS or adjust points per purchase value.

 If You Need More Control

• Some third-party POS loyalty modules offer referral or signup bonuses built-in (search Odoo Apps Store for “pos loyalty”).
• For advanced behavior (e.g., bonus only in specific stores), you might add a custom server action with a domain filter.
