# Heleket

{% hint style="info" %}
If you need to update a module on the server, please refer to the [instructions](https://premium.gitbook.io/main/en/en/basic-settings/faq/updating-script-files-on-the-server/how-to-update-files-on-the-server#merchant-and-auto-payout-modules).

{% hint style="danger" %}
Starting June 23, 2025, an additional fee of 1 TRX will be charged for the first payment to each new static address (the "**Address**" field in the merchant module settings) on the USDT TRC20 network.

This change does not affect static addresses in other currencies and networks (such as USDT BEP20 and others) or temporary addresses (the "**Invoice**" field).

Fill in the required authorization fields.

<figure><img src="/files/hVr2X7kYgIfi8A0o3dXc" alt="" width="460"><figcaption></figcaption></figure>

**Merchant ID** — **Merchant ID** from your Heleket account

**Api key** — **Payment API key** generated in your Heleket account

## Special Fields

<figure><img src="/files/HNZwb31huqGJuzDhXWHX" alt="" width="329"><figcaption></figcaption></figure>

**Type** — the type of wallet that will be issued in the request (a new wallet for each request)\
• **Invoice** — a temporary wallet address created for a specific transaction, which has a limited lifespan after being issued in the request (receiving funds to this wallet is **time-limited** — 12 hours from the moment of issuance in the request)\
\&#xNAN;*For this type of wallet, a cron job must be created on the server.*\
• **Address** — a permanent wallet address linked to your account with the merchant, with no lifespan limitation (receiving funds to this wallet is **not time-limited**)\
\&#xNAN;*Payment status is checked via callback; a cron job is not required for this type of wallet.*

{% hint style="warning" %}
When using invoices, we recommend mentioning this in the request text so that the client does not send funds to the wallet after the invoice has expired.
{% endhint %}

**Currency Code** — specify the code of the currency being accepted according to the merchant's requirements.

**Network** — specify the network of the accepted currency according to the merchant's requirements.

## 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://premium.gitbook.io/main/en/basic-settings/merchants-and-auto-payments/merchants/heleket.md?ask=<question>&goal=<endgoal>
```

`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.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
