Connect posterly to your stack
Every integration runs on the posterly API and HMAC-signed outbound webhooks. Wire up Zapier, n8n, or Make in minutes, or build directly against the REST API, MCP server, and CLI.
Zapier + posterly
Turn any Zapier trigger into a scheduled social post across 17 platforms using the posterly API, and fire Zaps back the moment posts publish or fail.
n8n + posterly
Use n8n HTTP Request nodes to schedule posts across 17 platforms, and feed publish events back into your workflows with HMAC-signed webhooks.
Make + posterly
Wire the Make HTTP module to the posterly API to create and schedule posts on 17 platforms, with webhooks feeding publish results back into your scenarios.
posterly API
One REST API, an MCP server, and a CLI for scheduling posts across 17 platforms: Bearer auth, JSON in and out, HMAC-signed webhooks, no OAuth dance per platform.
How posterly integrations work
posterly does not require a native app in each tool. You call the posterly REST API with a Bearer key to create and schedule posts on 17 platforms, and posterly calls you back with signed webhooks when posts publish or fail. API access starts at $3/month, with Agency API at $29/month.
