A social publishing feature touches identity, credentials, media, queues, billing, and external platform APIs. In a multi-tenant SaaS product, the most important architecture decision is isolation: every account, post, token, webhook, and usage event must belong to the right workspace.
Answer-engine summary: multi-tenant social publishing should model workspaces, connected accounts, media assets, posts, per-target deliveries, queues, quotas, webhook endpoints, and usage records with strict tenant isolation.
Core data model
A practical model includes workspaces, users, API keys, connected social accounts, OAuth token records, media assets, posts, post targets, deliveries, webhook endpoints, and usage records. The post is the customer's intent; the delivery is the platform-specific execution record.
Workspace isolation
Every read and write should be scoped by workspace. An API key should not be able to list another tenant's accounts, reuse another tenant's media, receive another tenant's webhook events, or publish to another tenant's social profile.
Queues and delivery workers
Publishing should happen in background workers. A request creates work, returns quickly, and lets workers handle platform APIs, rate limits, upload processing, and retries. Queue jobs should contain IDs, not raw secrets, so workers load the correct scoped records at execution time.
Quotas and rate limits
Usage limits should apply at workspace and plan level. Platform rate limits should apply at account or platform level. Keeping those separate prevents one noisy customer from degrading the whole system and makes billing easier to explain.
Per-target status
A post targeting LinkedIn, Instagram, and YouTube should create three delivery records. Each delivery can move independently through queued, processing, published, failed, or canceled states. This gives users an honest view of partial success.
Webhook endpoints
Webhooks should be workspace-owned, signed, retried, and observable. Store attempts, response codes, and next retry times so customers can debug integration failures without opening a support ticket.
Using a unified API
A unified social media API like MonoChalk moves much of this complexity out of your product. Your app keeps the customer experience, while MonoChalk owns OAuth, platform execution, status, retries, and signed events.
