Modern software runs on connections, between people, systems, and time itself. At the heart of this connectivity lies the Calendar API<\/span><\/a>, a vital component enabling apps to read, create, and synchronize calendar events seamlessly.<\/p>\n

Whether you\u2019re building a CRM, recruiting platform, or productivity suite, integrating a Calendar API allows you to manage availability, and sync data in real time across Google, Outlook.<\/p>\n

This guide will walk you through everything developers need to know, from how Calendar APIs work to how you can unify multiple calendar providers using Unipile\u2019s unified API.<\/p>\n

A Calendar API (Application Programming Interface)<\/strong> allows applications to access, create, and manage calendar events directly through code.
Instead of manually handling iCal or CalDAV formats, developers can rely on a modern RESTful layer<\/strong> that interacts with Google and Outlook calendars using JSON.<\/p>[\/et_pb_text][et_pb_button button_url=”@ET-DC@eyJkeW5hbWljIjp0cnVlLCJjb250ZW50IjoicG9zdF9saW5rX3VybF9wYWdlIiwic2V0dGluZ3MiOnsicG9zdF9pZCI6IjI1MjUwMSJ9fQ==@” button_text=”Calendar API” button_alignment_phone=”center” button_alignment_last_edited=”off|desktop” _builder_version=”4.27.4″ _dynamic_attributes=”button_url” _module_preset=”3de041fb-2406-416c-bc8e-0ce8db6d9822″ button_text_color=”#0F2736″ button_bg_color=”#DDDF4C” button_icon_color=”#0F2736″ transform_translate_linked__hover=”off” custom_margin=”50px||10px|0px|false|false” locked=”off” global_colors_info=”{}” button_bg_color__hover_enabled=”off|hover” button_bg_color__hover=”RGBA(255,255,255,0)” transform_styles__hover_enabled=”on|hover” transform_scale__hover_enabled=”on|hover” transform_translate__hover_enabled=”on|desktop” transform_rotate__hover_enabled=”on|desktop” transform_skew__hover_enabled=”on|desktop” transform_origin__hover_enabled=”on|desktop” transform_translate__hover=”0px|-5px” theme_builder_area=”post_content”][\/et_pb_button][\/et_pb_column][et_pb_column type=”1_2″ module_class=”second-on-mobile” _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.27.4″ _module_preset=”e341d6e8-e0ee-4548-817b-3f4b56727ce9″ text_font_size=”16px” text_font_size_last_edited=”off|desktop” global_colors_info=”{}” theme_builder_area=”post_content”]

A Calendar API integration follows a predictable, secure flow that lets your app read and write calendar data (events, attendees, reminders) across providers like Google and Outlook, through a single, normalized interface.<\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row disabled_on=”off|off|off” _builder_version=”4.27.4″ _module_preset=”default” custom_margin=”90px|auto|90px|auto|false|false” custom_margin_tablet=”90px|auto|90px|auto|false|false” custom_margin_phone=”0px|0px||0px|false|false” custom_margin_last_edited=”on|phone” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.22.2″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_image src=”https:\/\/www.unipile.com\/wp-content\/uploads\/2024\/12\/CALENDAR-API-documentation-6.webp” alt=”Outlook Email API integration with Unipile to send and retrieve emails” title_text=”CALENDAR API documentation (6)” align=”center” _builder_version=”4.27.4″ _module_preset=”default” width=”61%” width_tablet=”90%” width_phone=”90%” width_last_edited=”on|desktop” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ disabled_on=”off|off|off” _builder_version=”4.27.4″ _module_preset=”default” custom_margin=”90px|auto|90px|auto|false|false” custom_margin_tablet=”90px|auto|90px|auto|false|false” custom_margin_phone=”0px|0px||0px|false|false” custom_margin_last_edited=”on|phone” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”1_2″ _builder_version=”4.22.2″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.27.4″ _module_preset=”21a0719c-e83a-47d5-95e0-61824a7ca967″ text_font_size=”16px” header_3_font=”Poppins|600|||||||” header_3_font_size=”30px” global_colors_info=”{}” theme_builder_area=”post_content”]
1) Authenticate the user (OAuth 2.0)<\/h3>\n
    \n
  • \n
    The user connects their Google or Microsoft account via OAuth.<\/p>\n<\/li>\n
  • \n
    Your backend receives an authorization code, exchanges it for an access token, and stores it securely (server-side).<\/p>\n<\/li>\n
  • \n
    Subsequent API calls include “Authorization: Bearer <access_token>”.<\/p>\n<\/li>\n<\/ul>[\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.22.2″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_code _builder_version=”4.27.4″ _module_preset=”default” background_color=”RGBA(255,255,255,0)” custom_margin=”|0px||0px|true|true” custom_padding=”0px||0px|0px|false|false” custom_css_free_form=”\/* Conteneur principal *\/||.code-block {||  background-color: #0f2736; \/* Couleur du fond *\/||  border-radius: 8px;||  overflow: hidden;||  font-family: ‘poppins’;||}||||\/* Bandeau sup\u00e9rieur *\/||.code-header {||  background-color: #1b3a4b;||  display: flex;||  align-items: center;||  padding: 0.5rem 1rem;||  position: relative;||}||||\/* Boutons en haut \u00e0 gauche (rouge, jaune, vert) *\/||.code-header .dot {||  height: 12px;||  width: 12px;||  border-radius: 50%;||  margin-right: 0.4rem;||}||.code-header .dot.red { background-color: #ff5f56; }||.code-header .dot.yellow { background-color: #ffbd2e; }||.code-header .dot.green { background-color: #27c93f; }||||\/* Titre dans le bandeau *\/||.code-header .title {||  color: #ffffff;||  font-weight: bold;||  flex: 1;||  text-align: left;||}||||\/* Bouton m\u00e9thode GET *\/||.code-header .method-button {||  background-color: #3BB98B;||  color: #ffffff;||  border: none;||  border-radius: 12px;||  padding: 0.2rem 0.9rem;||  font-size: 12px;||  font-weight: bold;||  text-transform: uppercase;||  cursor: default;||}||||\/* Contenu du code *\/||pre {||  margin: 0;||  padding: 0rem 0.9rem;||  color: #ffffff;||  line-height: 1.2;||  font-size: 14px;||  overflow-x: auto;||}||||code {||  color: #ffffff;||}||||code .keyword { color: #ffffff; } \/* Exemple pour styliser les mots-cl\u00e9s *\/||code .string { color: #ffffff; }  \/* Exemple pour styliser les cha\u00eenes *\/||code .command { color: #ffffff; } \/* Exemple pour les commandes *\/||” locked=”off” global_colors_info=”{}” theme_builder_area=”post_content”]
