@postio/n8n-nodes-postio
An n8n community node for Postio — UK address lookup, postcode autocomplete, email validation and phone validation on official Royal Mail PAF data.
Operations
| Resource | Operation | What it does |
|---|---|---|
| Address | Search | Typeahead: a partial address or postcode → suggestions, each with a UDPRN |
| Address | Get by UDPRN | One full Royal Mail PAF address from its UDPRN |
| Address | List by Postcode | Every delivery point on a UK postcode |
| Validate | Syntax, MX, live SMTP probe, disposable/role flags, typo suggestion | |
| Phone | Validate | E.164 normalisation, live carrier lookup, line type, reachability |
Address search is free; you pay only when a full address is returned. Email and phone are billed per lookup. Pay as you go, 100 free lookups on sign-up, no contracts — see postio.co.uk/pricing.
Install
In n8n: Settings → Community Nodes → Install and enter @postio/n8n-nodes-postio. Or on a self-hosted instance:
npm install @postio/n8n-nodes-postio
Credentials
Create a Postio API credential with your API key (pk_…). Get one free at postio.co.uk/signup. The credential test calls GET /v1/connect.
Compatibility
Tested against n8n 1.x. No runtime dependencies — every operation is a declarative HTTP request against https://api.postio.co.uk/v1, matching the public OpenAPI spec.
