Example

Example workflow

A realistic scenario showing time and outcome.

Scenario: A marketing team schedules a 5-slide Carousel with caption "Spring Launch" in Google Sheets. The agent checks every 5 minutes, uploads five images from Drive to Cloudinary, creates the Carousel media, posts to IG via Graph API at the scheduled time, and logs success. Outcome: Carousel posted on time with the correct caption and media, and a publish log is recorded for audit.

FAQ

FAQ

Common concerns with practical, detailed answers.

You need an Instagram Business or Creator account connected to a Facebook Page, with a configured Facebook App and Graph API access. The workflow uses a Page access token and your ig_business_id to publish content. You may need permissions such as instagram_basic and instagram_content_publish. Ensure tokens and IDs are stored securely and rotated as needed. Test publishing in a staging environment before live use.

By default, the agent polls the Google Sheet every five minutes. The interval can be adjusted to match your publishing cadence. If no new ToDo items are found, the agent remains idle until the next check. Errors trigger retries and alerts according to your configuration. This keeps posting timely without manual intervention.

Yes. You can modify the status marker (e.g., ToDo) and add additional filters for content types or campaigns. The workflow supports changing the trigger interval and the data fields pulled from Google Sheets. You can layer in extra conditions to control when a post proceeds to publish. Any change is handled without needing to alter the core publishing logic.

The agent logs the error details, retries a limited number of times, and then notifies the team if the issue persists. Upload failures do not block other posts if configured to continue on error. The system records the failed attempt for audit and troubleshooting. Users can re-run or re-upload the assets to resume publishing.

Captions are prepared to meet Instagram limits (up to 2,200 characters). Hashtags can be appended or integrated into the caption automatically. If a caption approaches the limit, the agent truncates thoughtfully to avoid breaking content. You can configure how hashtags are added and where they appear in the caption.

Yes. You can publish to multiple IG accounts by configuring separate ig_business_id contexts and credentials. Each post references the appropriate account’s tokens and IDs. The workflow supports routing media and captions to the chosen account. This is ideal for managing client or brand portfolios from a single orchestrated setup.

The agent detects API outages and schedules retries within configured backoff rules. It logs the failure with timestamp details and notifies the designated channel. During outages, posts in ToDo remain queued and are retried automatically when the API becomes available. You maintain visibility into the retry status and overall publishing health.
