Frequently Asked Questions
How do I install the PostFast n8n node?
Because the node is verified by n8n, you install it right from the editor: click the + to open the nodes panel, search for PostFast, and add the verified node (an instance owner approves it once for the whole instance). This works on n8n Cloud and self-hosted instances running n8n 1.94 or later. On older self-hosted setups you can still install the community package with npm install n8n-nodes-postfast and restart n8n.
Is the n8n node officially supported?
Yes. The PostFast node is a verified community node: it is listed in the official n8n integrations directory and has been reviewed and verified by n8n. It is built and maintained by the PostFast team.
Can I use this on n8n Cloud, or only self-hosted?
Both. The verified node runs on n8n Cloud and on self-hosted instances. n8n Cloud gives you the node with zero maintenance; self-hosting gives agencies and enterprises full control over their data.
What credentials do I need?
You'll need a PostFast API key which you can generate from your PostFast dashboard under Settings > API Keys.
