<p>Lots of Telegram API methods provide access to potentially large lists of objects, which requires pagination.</p>
|
||||
<p>In order to fetch only relevant subset of results for each request there is a number of available input parameters. Here is a list in order how they are applied in API.</p>
|
||||
<p>Typically, results are returned in reverse chronological order with descending object ID values.</p>
|
||||
<h3><a class="anchor" name="limit-parameter" href="#limit-parameter"><i class="anchor-icon"></i></a><code>limit</code> parameter</h3>
|
||||
<h3><a class="anchor" href="#limit-parameter" id="limit-parameter" name="limit-parameter"><i class="anchor-icon"></i></a><code>limit</code> parameter</h3>
|
||||
<p>A limit on the number of objects to be returned, typically between 1 and 100. When 0 is provided the limit will often default to an intermediate value like ~20.</p>
|
||||
<h3><a class="anchor" name="offset-based-pagination" href="#offset-based-pagination"><i class="anchor-icon"></i></a><code>offset</code>-based pagination</h3>
|
||||
<h3><a class="anchor" href="#offset-based-pagination" id="offset-based-pagination" name="offset-based-pagination"><i class="anchor-icon"></i></a><code>offset</code>-based pagination</h3>
|
||||
<p>For a few methods with mostly static data this parameter allows to skip <code>offset</code> elements from the beginning of list; negative values are ignored.</p>
|
||||
<h3><a class="anchor" name="offset-id-based-pagination" href="#offset-id-based-pagination"><i class="anchor-icon"></i></a><code>offset_id</code>-based pagination</h3>
|
||||
<h3><a class="anchor" href="#offset-id-based-pagination" id="offset-id-based-pagination" name="offset-id-based-pagination"><i class="anchor-icon"></i></a><code>offset_id</code>-based pagination</h3>
|
||||
<p>For most methods where results are real-time data (e.g. any chat history) <code>offset</code> value is not passed directly. Instead it is calculated from the passed <code>offset_id</code> and <code>add_offset</code> parameter values as <code>offsetFromID(offset_id) + add_offset</code>, where <code>offsetFromID(offset_id)</code> is a number of results from the beginning of list up to the result with ID <code>offset_id</code>, inclusive.</p>
|
||||
<p>Sample use cases:</p>
|
||||
<ul>
|
||||
<li>Loading 20 messages, older than message with ID <code>MSGID</code>:</li>
|
||||
<li>

|

<p>When the client has cached results for API request, it can calculate the <code>hash</code> value for it by taking the result IDs (message IDs or other fields with name <code>id</code>) and using them to compute a 64-bit hash with the following algorithm:</p>
