Mallary vs the Facebook Graph API

Directly integrating with the Facebook API is difficult. Mallary makes it simple by handling rate limits, authentication, and deployment so engineering teams ship faster.

Using the Facebook Graph API:

Facebook Business verification required
Extensive review of scopes required
Frequent updates due to Graph API changes
Complex OAuth setup needed
Separate integrations per platform required

Using the Mallary API:

Official verified and approved permission to post on Facebook
One unified API for Facebook and 9 other platforms
Automatic token refresh and management
Built-in AI auto-replies and engagement
Automatic retries and rate limit handling
We handle OAuth, media hosting, and breaking API changes
US Based Servers. Post using API, CLI, MCP Server, or dashboard and your content will be posted from the US

Answers questions. Supports CTAs, links, and follow-ups
