Facebook API

Posting to Facebook via RelayAPI — features, limits, and platform-specific settings.

Overview

RelayAPI supports publishing to Facebook through the unified API. Connect your Facebook account and start posting programmatically.

Getting Started

1. Connect your Facebook account via the dashboard or Connect Account API
2. Use the account ID as a target when creating posts

curl -X POST https://api.relayapi.dev/v1/posts \
  -H "Authorization: Bearer rlay_live_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "Hello from RelayAPI!",
    "targets": ["acc_facebook_123"]
  }'

Content Limits

Platform-Specific Settings

Use platform_overrides to customize content for Facebook:

{
  "content": "Default content for all platforms",
  "platform_overrides": {
    "facebook": {
      "content": "Custom content for Facebook"
    }
  }
}

Rate Limits

Facebook enforces its own rate limits. RelayAPI automatically queues and retries posts when platform rate limits are reached. See Rate Limits for details.
