How to schedule Google Business posts via API
To schedule Google Business posts via API, connect Google Business through Modiva, then call `posts_schedule` with your content and a `publish_at` timestamp — Modiva queues it and publishes to Google Business automatically at that time.
Scheduling means storing a post and reliably publishing it later — something Google Business's API leaves entirely to you. Modiva runs the queue, retries on transient Google Business errors, and exposes one `posts_schedule` tool that works identically across every platform.
Step by step
Create a Modiva account and MCP key
Sign up free and generate an MCP key (`mk_live_…`) from the dashboard. The same key authenticates both the hosted MCP server (for AI agents) and the REST API (for your backend), so you only manage one credential.
Connect your Google Business account
From the dashboard, click Connect and choose Google Business. Modiva runs the OAuth flow and requests the right scopes for you, then stores the access + refresh tokens in an encrypted vault and keeps them fresh — you never handle Google Business's raw API credentials. The connection gets a stable `connectionId` you reference in every call.
Call posts_schedule with a publish_at time
Invoke `posts_schedule` with the connection ID, your content and an ISO `publish_at` timestamp. Modiva stores the job and publishes to Google Business at that moment, handling token refresh and retries without you running any cron.
Find the best time and batch a calendar
Call `analytics_best_time_to_post` to pick a slot, then schedule a whole week in a loop. Over MCP, an AI agent can plan and queue a full Google Business content calendar from a single prompt.
Example request
Call the posts_schedule tool through Modiva’s REST API. The same tool is available to AI agents over the MCP server at https://mcp.modiva.ai/v1.
curl -X POST https://api.modiva.ai/v1/tools/invoke \

Does Modiva run the scheduler, or do I?
Modiva does. Once you call `posts_schedule`, Modiva stores the job and publishes to Google Business at the requested time — you don't need your own queue or cron.
Can I schedule the same post to several platforms?
Yes — pass multiple connection IDs (or use `posts_cross_post`) and Modiva schedules the post to Google Business and every other platform, adapted to each format.
