**Is this a different API from the Delivery API?**
It is the same GraphQL endpoint, schema and token. The CRM & Loyalty pages cover the customer and loyalty part.

**How do I find a customer by phone number?**
Use `customers.customer(phone: ...)`. See **Customer Identification**.

**The search returned more than one customer. What now?**
Check `totalCount`. Add the first name, the last name or the code to narrow the result.

**Where is the points balance?**
In `loyalty.points.balance` of the customer. See **Customer Details**.

**Are points whole numbers?**
No. Points and amounts are decimal numbers, for example `5.61`.

**How do I see the points of a receipt?**
Read `receipts.loyalty.points.credit` (earned) and `debit` (used) with `order.orders`. See **Points Balance & Transactions**.

**Why is my `orders` request rejected?**
`orders` needs order keys or a period of at most 1 year.

**How do I get the full history of a customer?**
Query one period of at most 1 year at a time and page through each one.

**Why is `segmentationCategory`** **`null`?**
The customer has no segmentation assigned.

**Can a voucher have no end date?**
No. `beginDate` and `endDate` are always set. `maximumUsageCount` `null` or `0` means unlimited uses.

**Can I read or redeem a gift card with this API?**
No. You can create a gift card. It is used at the POS when the customer buys something.

**How do I update only one field of a customer?**
Send the `publicKey` and that field. All the other fields are optional.

**I deleted a customer. Is it gone?**
The delete is soft. The customer becomes inactive and doesn't appear in the default lists.

**Can I get notified when points change?**
Not in this API. Query the data when you need it. The Delivery API has webhooks, for its own events.

**How do I get a token?**
See **Authentication**. The same token works for the Delivery API.
