| Status         | `409`                                                    |
| Problem `type` | `https://docs.paypathiq.com/problems/dependency_missing` |
| Retryable      | No                                                       |

## When this happens

A record the request refers to does not exist for your Integration and Client. A Receivable refers to a Customer that has not been created. A Payment observation refers to a Receivable that has not been created. A refund or reversal refers to a Payment observation that does not exist or is not a `payment`. PayPathIQ does not create the missing record or queue the request.

## What to do

Create the referenced record first, then send this request again. Create Customers, then Receivables, then Payment observations.
