<p>On startup, clients should fetch the animated emoji stickerset by calling the <ahref="/method/messages.getStickerSet">messages.getStickerSet</a> method, providing <ahref="/constructor/inputStickerSetAnimatedEmoji">inputStickerSetAnimatedEmoji</a> to the <code>stickerset</code> field.<br>
The returned stickerset will contain a set of animated stickers, one for each of the supported emojis. </p>
<p>Clients should substitute messages containing only one instance of one of the allowed emojis with the respective animated sticker. </p>
<p>Animated emojis should loop only once when first sent or received, or when clicked.<br>
For <ahref="#emoji-reactions">supported emojis</a>, clients on both sides of private chats with users are supposed to show a reaction animation when any of the two users clicks on the animated emoji: <ahref="#emoji-reactions">click here for more info »</a>.</p>
<p>For special <ahref="/api/dice">dice emojis</a> like <imgclass="emoji"src="//telegram.org/img/emoji/40/F09F8EB2.png"width="20"height="20"alt="🎲"/>, <imgclass="emoji"src="//telegram.org/img/emoji/40/F09F8EAF.png"width="20"height="20"alt="🎯"/>, or <imgclass="emoji"src="//telegram.org/img/emoji/40/F09F8F80.png"width="20"height="20"alt="🏀"/>, clients are supposed to behave differently both when sending and receiving such emojis: <ahref="/api/dice">click here for more info »</a>.</p>
<h3><aclass="anchor"href="#emojis-with-sounds"id="emojis-with-sounds"name="emojis-with-sounds"><iclass="anchor-icon"></i></a>Emojis with sounds</h3>
<p>Certained animated emojis should play sound when clicked, as specified by <ahref="/api/config#client-configuration">server-side configuration</a>. </p>
<p>The returned JSON object will contain the following map, with a list of file IDs to download:</p>
<p>On startup, clients should fetch the animated reaction emoji stickerset by calling the <ahref="/method/messages.getStickerSet">messages.getStickerSet</a> method, providing <ahref="/constructor/inputStickerSetAnimatedEmojiAnimations">inputStickerSetAnimatedEmojiAnimations</a> to the <code>stickerset</code> field.<br>
The returned stickerset will contain a set of animated emoji reactions, <em>one or more</em> for each of the supported emojis.<br>
If a set of reactions for the <imgclass="emoji"src="//telegram.org/img/emoji/40/E29DA4.png"width="20"height="20"alt="❤"/> emoji is returned, the same reactions should also be assigned to the <imgclass="emoji"src="//telegram.org/img/emoji/40/F09FA7A1.png"width="20"height="20"alt="🧡"/>, <imgclass="emoji"src="//telegram.org/img/emoji/40/F09F929B.png"width="20"height="20"alt="💛"/>, <imgclass="emoji"src="//telegram.org/img/emoji/40/F09F929A.png"width="20"height="20"alt="💚"/>, <imgclass="emoji"src="//telegram.org/img/emoji/40/F09F9299.png"width="20"height="20"alt="💙"/>, <imgclass="emoji"src="//telegram.org/img/emoji/40/F09F929C.png"width="20"height="20"alt="💜"/>, <imgclass="emoji"src="//telegram.org/img/emoji/40/F09F96A4.png"width="20"height="20"alt="🖤"/>, <imgclass="emoji"src="//telegram.org/img/emoji/40/F09FA48D.png"width="20"height="20"alt="🤍"/> and <imgclass="emoji"src="//telegram.org/img/emoji/40/F09FA48E.png"width="20"height="20"alt="🤎"/> emojis. </p>
<p>Clients on both sides of private chats with users should overlay one of the appropriate reaction animations over the animated sticker when any of the two users clicks on a supported animated emoji.<br>
The reaction animation for each separate tap should be chosen randomly from all the available reactions for a given emoji, and multiple taps should be aggregated and sent to the other user as follows: </p>
<p>At each tap, clients should store the relative timestamp of the tap (starting from the first one @ <code>0</code>) in a list.<br>
After 500 milliseconds have elapsed with no more taps, the list should be cleared and stored taps should be sent using <ahref="/method/messages.setTyping">messages.setTyping</a>, passing a <ahref="/constructor/sendMessageEmojiInteraction">sendMessageEmojiInteraction</a> constructor with the following fields: </p>
<li><code>v</code> - An integer indicating the object version, currently <code>1</code></li>
<li><code>a</code> - An array of JSON objects, each containing the following keys:<ul>
<li><code>t</code> - float, relative timestamp of the tap in seconds, the first one being <code>0.0</code>.</li>
<li><code>i</code> - integer, 1-based index of the randomly chosen animation for the tap (equivalent to the index of a specific emoji-related animation in <ahref="/constructor/stickerPack">stickerPack</a> + 1).</li>
