<p>You can accept payments from Telegram users via <a href="/bots">Telegram Bots</a>.</p>

<h3><a class="anchor" href="#introducing-payments" id="introducing-payments" name="introducing-payments"><i class="anchor-icon"></i></a>Introducing Payments</h3>
<p>Telegram bots can accept payments for goods and services from users.
For more info on how payments work, check out the <a href="https://telegram.org/blog/payments">Telegram Blog</a> and the <a href="/bots/payments">bot API payment manual</a>.</p>
<p>This page will elaborate on the actions required to work with payments using the <strong>MTProto API</strong>.</p>
<blockquote>
<p>A simplified version of the process is available only for bots using the <a href="/bots/payments">bot API</a>.</p>
</blockquote>
<p>The first step for bots is <a href="/bots/payments#the-payments-api">enable payments as described here »</a>.</p>
<p>Then, we work with payments as follows.</p>

<p>The user contacts the bot and requests to purchase something.
The bot forms an <a href="/constructor/inputMediaInvoice">inputMediaInvoice</a> with an <a href="/constructor/invoice">invoice</a> constructor with a description of the goods or service, amount to be paid, as well as requested shipping info.
The <code>provider</code> parameter of the <a href="/constructor/inputMediaInvoice">inputMediaInvoice</a> constructor is where you put the token value that <a href="/bots/payments#the-payments-api">you've obtained earlier via Botfather</a>. It is possible for one merchant bot to use several different tokens for different users or different goods and services.</p>
<p>Use the <a href="/method/messages.sendMedia">messages.sendMedia</a> method to send the <a href="/constructor/invoice">invoice</a>.
You can also attach an inline keyboard to the message using the <code>reply_markup</code> field: if provided, the first button must be a <a href="/constructor/keyboardButtonBuy">keyboardButtonBuy</a> button. Otherwise, an inline keyboard will be generated automatically, with a <code>Pay 'total price'</code> <a href="/constructor/keyboardButtonBuy">keyboardButtonBuy</a> as only button.</p>
<p>An invoice message with a pay button can only be sent to a private chat with the user. Groups and channels are not supported.</p>

Once the user finishes working with the webpage, the client can <a href="#5-checkout">proceed to checkout</a>.</p>
<p>Eventual errors are returned in the form of RPC errors (<code>rpc_error</code>), with the description of the error by the bot contained in additional <a href="/constructor/updateServiceNotification">service updates</a> received separately, see <a href="/api/errors#406-not-acceptable">here</a> for more info. </p>
<p>Note that eventual payment errors will not be sent to the client via MTProto if they occur during additional verification (if a <a href="/constructor/payments.paymentVerificationNeeded">payments.paymentVerificationNeeded</a> is returned and the user fails TOTP verification): such errors will only be displayed inside of the verification webview, no MTProto updates or RPC errors (<code>rpc_error</code>) will be received. </p>

<p>The user enters their payment information as described above and presses the final pay button.
At this moment the Telegram API sends an <a href="/constructor/updateBotPrecheckoutQuery">updateBotPrecheckoutQuery</a> constructor that contains all the available information about the order to the bot.
The bot must reply using <a href="/method/messages.setBotPrecheckoutResults">messages.setBotPrecheckoutResults</a> <strong>within 10 seconds</strong> after receiving this update or the transaction is canceled.</p>
<p>The bot may return an error if it can't process the order for any reason. We highly recommend specifying a reason for failure to complete the order in human readable form (e.g. "Sorry, we're all out of rubber ducks! Would you be interested in a steel bear instead?"). Telegram will display this reason to the user.</p>

<p>In case the bot confirms the order, Telegram requests the payment provider to complete the transaction. If the payment information was entered correctly and the payment goes through, the Telegram API will modify the invoice message and send a service message as described below. Once your bot receives this message, it should proceed with delivering the goods or services purchased by the user.</p>
<p>If all is OK, the user receives a <a href="/constructor/payments.paymentResult">payments.paymentResult</a> in reply to the <a href="/method/payments.sendPaymentForm">payments.sendPaymentForm</a> query, containing info about the updated invoice message in the form of an <a href="/constructor/updateEditMessage">updateEditMessage</a>.</p>
<p>The invoice message will be updated as follows: the attached <a href="/constructor/messageMediaInvoice">messageMediaInvoice</a> will now have a <code>receipt_msg_id</code> field.
Clients should treat invoice messages with a <code>receipt_msg_id</code> field as receipt messages, <strong>locally</strong> modifying the label of the <a href="/constructor/keyboardButtonBuy">keyboardButtonBuy</a> button to a localized version of the word <code>Receipt</code>.
From this point, clicking on the <code>Receipt</code> button should trigger a call to <a href="/method/payments.getPaymentReceipt">payments.getPaymentReceipt</a>, providing the <code>receipt_msg_id</code> to the <code>msg_id</code> field, which will return info about the transaction.</p>
<p>The payment will also generate one service message of type <a href="/constructor/messageActionPaymentSent">messageActionPaymentSent</a> or <a href="/constructor/messageActionPaymentSentMe">messageActionPaymentSentMe</a>, replying to the invoice.
For bots, the service message will be of type <a href="/constructor/messageActionPaymentSentMe">messageActionPaymentSentMe</a>, for users it will be a <a href="/constructor/messageActionPaymentSent">messageActionPaymentSent</a>.<br>
The <code>recurring_init</code> flag will be set if this payment also enables future recurring payments.<br>
Further recurring payments will automatically send <a href="/constructor/messageActionPaymentSentMe">messageActionPaymentSentMe</a> and <a href="/constructor/messageActionPaymentSent">messageActionPaymentSent</a> messages with the <code>recurring_used</code> flag set. </p>
