# Top-up errors
Partial payment on the invoice (Error code: #P003)
**Reasons for occurrence**
The error occurs if a smaller amount was credited to the invoice than required. For example, you selected a payment method for a specific amount, but actually transferred less.
The system records an incomplete payment and the funds are not credited to the card.
**What should I do?**
Check the amount you sent and compare it with the amount specified in the invoice.
If you have any difficulties, contact support via [@WantToPaySupportBot](https://telegram.me/WantToPaySupportBot) — we will tell you how to add the missing amount.
Crypto payment confirmation (Error code: #P004)
**Reasons for occurrence**
The crypto payment was sent, but it requires confirmation on the payment service side. In such cases, the funds are not credited automatically, and the transaction remains in the “uncompleted” status.
This is a standard situation in which the payment temporarily “hangs” until it is confirmed manually.
**What should I do?**
If you received this notification, contact the payment service to confirm the transfer.
For payments via Cryptomus, contact [@cryptomus\_support\_bot](https://telegram.me/cryptomus_support_bot).
{% hint style="info" %}
If you still have questions or the payment is not confirmed for a long time — write to us in support: [@WantToPaySupportBot](https://telegram.me/WantToPaySupportBot), we will help you figure it out.
{% endhint %}
Payment is being processed (Error code: #P005)
If you are topping up your balance with an amount over $2000, your payment may be subject to an additional check. In this case, you will receive a notification:
> ⏳ *The payment is being processed. In rare cases, this can take up to 12 hours.* Error code: #P005
This is not an error, but a temporary delay related to the verification of a large deposit. As soon as the verification is complete, the funds will be credited to the card.
We recommend waiting some time after the deposit. If the money has not been credited — write to support [@WantToPaySupportBot](https://telegram.me/WantToPaySupportBot)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://faq.wanttopay.net/wanttopay-app/english/errors-and-solutions/top-up-errors.md?ask=&goal=

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
