Create a custom earning rule in Okendo
In your Okendo admin, navigate to the Loyalty Program and create a new custom earning rule for purchases. Set the Action Type to Award a variable amount of points and configure the Points Earned rate (e.g.1 point per 1 dollar). Subtotal will pass the purchase total as the value, and Okendo will multiply by your configured rate to determine points awarded.

Action ID — you’ll need it in the next step.
Points are calculated by Okendo using the Points Earned rate configured on this rule. Subtotal sends the raw dollar amount of the purchase; the conversion to points happens on Okendo’s side.
Add the action in Subtotal
In the Subtotal Dashboard, navigate to your Okendo integration and clickAdd action.
Choose purchase.created as the event, give the action a name, optionally restrict to specific retailers, paste the Okendo earning rule’s Action ID into the Okendo earning rule ID field, and set a Start date. Subtotal will only reward purchases made on or after the start date — this controls how much historical purchase data gets sent to Okendo when a customer first links their account.

Create. Subtotal will now trigger this earning rule for each purchase it collects on a linked account.
