What you need before you start

Social Rainbow in Claude

Add the connector from the connectors directory and sign in to the workspace that owns the social accounts.

Facebook Page

You must be authorized to connect and publish to the selected Facebook Page.

How to post to Facebook from Claude

  1. Add Social Rainbow to Claude

    Start the Social Rainbow trial, then open the connectors directory, find Social Rainbow, choose Connect, and sign in with the same Social Rainbow account.

  2. Connect your Facebook Page

    Choose the Facebook & Instagram connection and complete the provider's authorization page. Return to Claude and list accounts again to confirm the connection.

  3. Draft for Facebook

    Use conversational copy with enough context to stand on its own. Make the next step or link explicit. Include any intended link or supported media before validation.

  4. Validate and review the exact preview

    Check every destination, the visible post text, link behavior, media, follow-ups, and platform options. Resolve warnings or errors before approval.

  5. Approve and publish

    Explicitly approve that exact preview. Social Rainbow publishes the unchanged payload and returns the actual publication job status.

A prompt you can copy

You do not need to name internal tools. State the outcome, destinations, source material, and approval requirement in plain language.

Example prompt for Claude“Adapt this into a Facebook post for my connected Facebook Page. Validate the final content, and show me the exact preview before publishing.”

Write for Facebook, not just at it

Use conversational copy with enough context to stand on its own. Make the next step or link explicit.

Supported content: text, link, image, and video posts. Media is optional for Facebook Page posts.

Media handling in Claude

For media posts, provide a direct public media URL that Social Rainbow can validate for the selected destination.

Media storage does not publish a post. The assistant still has to validate the destination, show the complete preview, receive approval, and call the final publish or schedule action.

What the final review should show

  • The exact connected account name and destination.
  • The final visible root post and any follow-ups or comments.
  • Every link, media item, and destination-specific option.
  • Warnings, normalization changes, or validation errors.

If anything changes after that review, validate the new version and approve it again. This keeps the user's approval tied to the content that will actually be sent.
