<p>These methods can be used for managing consent to Telegram's <a href="https://telegram.org/tos">Terms Of Service</a>. </p>
<p>Typically, before a user <a href="/api/auth#sign-in-sign-up">signs up</a> by invoking <a href="/method/auth.signUp">auth.signUp</a>, apps should show a pop-up (if the <code>popup</code> flag of the <a href="/constructor/help.termsOfService">help.termsOfService</a> method is set), asking the user to accept Telegram's terms of service; in case of denial, the user is to be returned to the initial page of the login flow. </p>
<p>When signing up for the first time, the <a href="/constructor/help.termsOfService">help.termsOfService</a> is to be obtained from the <a href="/constructor/auth.authorizationSignUpRequired">auth.authorizationSignUpRequired</a> constructor returned by the <a href="/method/auth.signIn">auth.signIn</a>. </p>
<p>After signing up, or when logging in as an existing user, apps are supposed to call <a href="/method/help.getTermsOfServiceUpdate">help.getTermsOfServiceUpdate</a> to check for any updates to the Terms of Service; this call should be repeated after <code>expires</code> seconds have elapsed.<br>
If an update to the Terms Of Service is available, clients are supposed to show a consent popup; if accepted, clients should call <a href="/method/help.acceptTermsOfService">help.acceptTermsOfService</a>, providing the <a href="/constructor/help.termsOfService">termsOfService <code>id</code> JSON object</a>; in case of denial, clients are to delete the account using <a href="/method/account.deleteAccount">account.deleteAccount</a>, providing <code>Decline ToS update</code> as deletion <code>reason</code>. </p>
