# CRM payments

After a confirmed write, the response normally contains the reread payment. If that follow-up read fails, a successful response contains only `data.id` (for a position, `data.id` and `data.payment.id`) and `meta.readbackUnavailable: true`. The write has completed; inspect the returned ID before retrying a POST.

Create a payment for a deal: Bitrix24 creates the linked order. For an existing order use [order payments](./payments.md) with the sale scope. Both surfaces use the same payment ID. Scope here: crm.

## Flow

[Available rows](./crm-payments/available-products.md) → [create payment](./crm-payments/create.md) with zero amount → [add position](./crm-payments/products-add.md) with rowId and integer quantity → [check amount](./crm-payments/get.md) → [mark paid](./crm-payments/pay.md). Marking paid does not transfer money and can trigger automation, email, or a fiscal receipt.
