Zoho Mail uses OAuth 2.0 for authentication. Truto handles the OAuth flow, token refresh, and multi-datacenter routing (Zoho operates separate domains for US, EU, IN, AU, and JP regions), so your end users simply authorize access through a standard consent screen. ### Are there specific Truto tools available for Zoho Mail today? Zoho Mail tools are built on request. The Unified Search API is available for querying mailbox data. If you need additional capabilities like sending emails, syncing threads, or extracting attachments, contact Truto and the team will scope and build the required tools for your use case. ### What Unified APIs does Truto support for Zoho Mail? Zoho Mail is currently supported under Truto's Unified Search API, which lets you query a user's mailbox for emails matching specific criteria like keywords, sender addresses, or date ranges. ### What are Zoho Mail's API rate limits? Zoho Mail enforces rate limits that vary by endpoint and plan tier, typically in the range of a few hundred calls per minute. Truto manages rate-limit handling, retries, and backoff automatically so your integration doesn't break under load. ### Does the integration support shared or group mailboxes? Zoho Mail supports shared mailboxes and group aliases. Whether your integration can access them depends on the OAuth scopes granted by the end user and their admin's permission policies. Truto passes through whatever access the authenticated user has. ### How does Truto handle Zoho's multi-region data centers? Zoho operates isolated data centers across multiple regions (US, EU, IN, AU, JP), each with its own API base URL. Truto automatically detects and routes API calls to the correct regional endpoint based on the user's account, so you don't need to manage this yourself.
