Your users want to publish from inside your app. You do not want to spend a quarter building that.

## The problem

Adding social publishing looks like one feature and is really nine. Each network has its own OAuth dance, its own media rules, its own review process, its own way of failing. Then they change, and it is nobody's job to notice until a customer complains.

## What PostLake does about it

### One integration, not nine

A single API covers every major network. Your code branches on nothing.

### No app reviews to chase

Platform credentials are managed for you, so you are not waiting on nine review queues before you can ship. If you would rather use your own, bring your keys and run white-label.

### Rules enforced before you send

Character limits, media requirements, pixel bounds and option values are checked up front, so your users get a clear message in your UI instead of a rejection from a network they have never heard of.

### Failures that reach you

Webhooks fire on published, failed and partial, so your product knows what happened without polling.

## How it fits together

Connect accounts with a signed link you can embed anywhere, post with one call, and receive webhooks. Most integrations are a few hundred lines.

## Common questions

**How long does it take to add social posting?**

Hours rather than weeks, because the platform-specific work is the part you are skipping. Connect an account, post with one call, handle a webhook.

**Do I need my own developer apps on each network?**

No. Platform credentials are managed for you by default, which is the part that normally takes the longest. If you want your own branding on the connection screen you can supply your own keys instead.

**What happens when a network changes its rules?**

The capability registry changes and every check follows it. You do not chase nine changelogs.
