Social Strategy

1. Account Setup

Profile Configuration

Meta Developer Setup

1. Convert to Professional Account — Instagram app → Settings → Account → Switch to Professional → Creator
2. Create Facebook Page — facebook.com/pages/create → Name: "Epoch" → Category: Art
3. Link Instagram to Facebook Page — Instagram → Settings → Linked Accounts → Facebook → select Epoch page
4. Register Meta Developer App — developers.facebook.com → My Apps → Create App → Type: Business → Name: "Epoch Social"
5. Add Instagram Graph API — In the app dashboard → Add Product → Instagram Graph API → Set Up
6. Request Permissions:
   • instagram_basic — read profile info
   • instagram_content_publish — post images, carousels, reels
   • instagram_manage_comments — read/reply to comments
   • instagram_manage_insights — engagement analytics
   • pages_show_list — required for page connection
   • pages_read_engagement — required for comment webhooks
7. Generate Long-Lived Token:
   • Graph API Explorer → select your app → select permissions → Generate User Token
   • Exchange for long-lived token (60 days): GET /oauth/access_token?grant_type=fb_exchange_token&client_id={APP_ID}&client_secret={APP_SECRET}&fb_exchange_token={SHORT_TOKEN}
   • Store as Firebase secret: firebase functions:secrets:set META_ACCESS_TOKEN
8. Get Instagram Business Account ID:
   • GET /me/accounts → get Page ID
   • GET /{page_id}?fields=instagram_business_account → get IG Account ID
   • Store as env variable or Firebase config

2. Content Strategy

Hashtag Strategy — Three-Tier System

Instagram 2026 recommends 3-5 hashtags, but 7-10 well-structured tags in three tiers performs best for niche content. The key: the content tier changes every post, keeping each post unique to the algorithm.

Tag Pools

Examples

Fashion post (Svan-Corsican fusion):
#aiart #generativeart #aifashion #fashionart      ← community
#epochfashion #aiagents #fluxai                  ← niche
#svancorsican #editorialai                       ← content

Traveler post (Osaka Day 3):
#aiart #generativeart #aiphotography              ← community
#epochtraveler #aiagents                         ← niche
#osaka #japan #streetfashion                      ← content

Pipeline post (behind the scenes):
#aiart #generativeart #aidesign                   ← community
#epochfashion #aiagents #claudeai #buildingwithai ← niche (heavier)
#agentpipeline #automation                        ← content

Rules

• Never repeat the exact same set on consecutive posts — the algorithm flags it as spam
• Always include one brand tag: #epochfashion or #epochtraveler
• Content tier must be unique — pulled from the post's actual era/city/mood metadata
• Place in caption (not first comment) for small/new accounts — 36% more reach
• C-Social agent will automate this: community + niche from rotating pool, content from post metadata

  Generates weekly report
  Feeds insights back into Fashion Director brief
  (the AI learns what the audience likes)

Firestore Collections

Cloud Functions (New)

Where Do These Functions Live?

Two options:

Recommendation: Option B — epoch-social. Social is a new vertical, not owned by Fashion or Traveler. It reads from both. Clean separation follows the Epoch architecture principle. The social queue pattern decouples posting from generation.

4. Daily Digest Email

Sent every morning at 7:00 AM CST. Your 5-minute command center.

5. Meta Graph API Reference

Post a Single Image

// Step 1: Create media container
POST https://graph.facebook.com/v19.0/{ig_account_id}/media
  ?image_url={public_image_url}
  &caption={caption_text}
  &access_token={token}

// Returns: { id: "container_id" }

// Step 2: Publish
POST https://graph.facebook.com/v19.0/{ig_account_id}/media_publish
  ?creation_id={container_id}
  &access_token={token}

// Returns: { id: "ig_media_id" }

Post a Carousel (Traveler)

// Step 1: Create child containers (one per image)
POST /media?image_url={url_1}&is_carousel_item=true
POST /media?image_url={url_2}&is_carousel_item=true
POST /media?image_url={url_3}&is_carousel_item=true

// Step 2: Create carousel container
POST /media
  ?media_type=CAROUSEL
  &children={child_id_1},{child_id_2},{child_id_3}
  &caption={caption}

// Step 3: Publish
POST /media_publish?creation_id={carousel_container_id}

Read Comments

GET /{ig_media_id}/comments
  ?fields=id,text,username,timestamp,replies
  &access_token={token}

Reply to a Comment

POST /{ig_comment_id}/replies
  ?message={reply_text}
  &access_token={token}

Get Insights

// Account-level insights
GET /{ig_account_id}/insights

  &period=day
  &since={unix_timestamp}
  &until={unix_timestamp}

// Per-post insights
GET /{ig_media_id}/insights
  ?metric=impressions,reach,engagement,saved

Webhook Setup (for real-time comments)

// In Meta Developer Dashboard:
// 1. Webhooks → Instagram → Subscribe to: comments
// 2. Callback URL: https://us-central1-epoch-social.cloudfunctions.net/socialCommentWebhook
// 3. Verify token: {your_verify_token} (stored in Firebase secrets)

// Webhook payload (incoming):
{
  "object": "instagram",
  "entry": [{
    "changes": [{
      "field": "comments",
      "value": {
        "id": "comment_id",
        "text": "user's comment text",
        "from": { "id": "user_id", "username": "user_name" },
        "media": { "id": "media_id" }
      }
    }]
  }]
}

6. Implementation Phases

7. Rules of Engagement

Green — Do Freely

Yellow — Agent Suggests, Human Acts

Red — Never

8. Token Management

Meta tokens expire. Here's the lifecycle:

Strategy: Generate a long-lived user token, then get a Page token from it. The Page token never expires. Use the Page token for all API calls. Store it as a Firebase secret.
