Batch create contacts
Create a batch of new contacts in Google Contacts. This action creates up to 200 contacts in a single API call and returns the PersonResponses for the newly created contacts. Use this action when you need to create multiple contacts at once to reduce API calls and improve performance. Mutate requests for the same user should be sent sequentially to avoid increased latency and failures. Note: The contacts array accepts Person objects with any valid People API fields (names, emailAddresses, phoneNumbers, addresses, organizations, etc.). Each contact must be wrapped in a 'contactPerson' object.
