Google People API now supports batch mutates and searches of Contacts
Blog post from Google Cloud
Google has announced the enhancement of the People API with new endpoints for batch operations and search functionalities, as part of the transition from the deprecated Google Contacts API, which will be discontinued on June 15, 2021. The updated People API now includes new write endpoints that support the creation, deletion, and updating of multiple contacts simultaneously, alongside new read endpoints that enable developers to search through a user's contacts using prefix queries. To use the People API, applications must be authorized through the Google Developers Console, and developers can leverage the Google APIs Client Library for Java to perform these operations. The expansion of these capabilities aims to facilitate the development of innovative web and mobile applications, with detailed documentation available to assist developers in implementing these new features.
