<h2 id="options-et-paramètres-de-suppression-dannotation">Options et paramètres de suppression d&rsquo;annotation</h2>
<p>Le SDK expose plusieurs paramètres que vous pouvez ajuster :</p>
<ul>
<li><strong>clientId / clientSecret</strong> - Identifiants pour l&rsquo;authentification OAuth. Définissez‑les dans le constructeur <code>Configuration</code>.</li>
<li><strong>fileInfo.filePath</strong> - Le chemin du PDF dans le stockage GroupDocs Cloud. Modifiez‑le si vous stockez les fichiers dans un autre dossier.</li>
<li><strong>annotationIds</strong> - Un tableau d&rsquo;ID renvoyés par <code>GetAnnotations</code>. Fournir un sous‑ensemble permet une suppression sélective.</li>
</ul>
<p>Des paramètres supplémentaires tels que les délais d’attente des requêtes et la configuration du proxy sont disponibles dans la documentation du SDK ; consultez la <a href="https://docs.groupdocs.cloud/annotation/">documentation officielle</a> pour la liste complète.</p>
<h2 id="meilleures-pratiques-pour-la-suppression-des-annotations-pdf-via-rest">Meilleures pratiques pour la suppression des annotations PDF via REST</h2>
<ul>
<li><strong>Valider les ID d&rsquo;annotation</strong> - Vérifiez toujours que les ID que vous prévoyez de supprimer existent ; tenter de supprimer des ID inexistants peut entraîner une erreur 404.</li>
<li><strong>Utiliser HTTPS</strong> - Toutes les appels d&rsquo;API doivent être effectués via HTTPS afin de protéger vos identifiants et les données du document.</li>
<li><strong>Gérer les gros fichiers avec des téléchargements fractionnés</strong> - Pour les PDF de plus de 100 Mo, privilégiez le point de terminaison de téléchargement multipart pour éviter les dépassements de délai.</li>
<li><strong>Consigner les réponses de l&rsquo;API</strong> - Enregistrez les ID de requête et les réponses pour les pistes d’audit et faciliter le dépannage.</li>
<li><strong>Réutiliser les jetons d&rsquo;accès</strong> - Mettez en cache le jeton OAuth jusqu&rsquo;à son expiration afin de réduire la charge d&rsquo;authentification.</li>
</ul>
<h2 id="questions-fréquentes">Questions fréquentes</h2>
<ul>
<li>
<p><strong>Comment m&rsquo;authentifier avec GroupDocs.Annotation Cloud API ?</strong><br>
Obtenez un ID client et un secret depuis votre compte GroupDocs, puis demandez un jeton d&rsquo;accès via le point de terminaison OAuth. Voir la <a href="https://docs.groupdocs.cloud/annotation/">documentation officielle</a> pour plus de détails.</p>
</li>
<li>
<p><strong>Puis-je supprimer des annotations spécifiques au lieu de toutes ?</strong><br>
Oui, fournissez les ID des annotations que vous souhaitez supprimer dans le DeleteAnnotationsRequest. Le SDK renvoie la liste des ID d’annotation après un appel GetAnnotations.</p>
</li>
<li>
<p><strong>How can I remove Annotation objects from PDF with REST in Node.JS?</strong><br>
Utilisez le GroupDocs.Annotation Cloud SDK for Node.js pour appeler le point de terminaison DeleteAnnotations après avoir récupéré les ID des annotations. Le flux complet est présenté dans l’exemple de code et la section cURL de ce guide.</p>
</li>
<li>
<p><strong>Quel type de licence est requis pour une utilisation en production ?</strong><br>
Une licence payante est nécessaire pour la production. Vous pouvez obtenir une licence temporaire depuis la <a href="https://purchase.groupdocs.cloud/temporary-license/">page de licence temporaire</a> lors de l&rsquo;évaluation.</p>
