Common Workflows
Review risky orders
Use Shopify, Stripe, WooCommerce, or another order trigger, then pass the customer’s email, phone, and IP address into 1Lookup. Route medium-risk or high-risk results to manual review, Slack, email, or your fraud operations queue.
Clean CRM records
Use records from HubSpot, Salesforce, Airtable, Google Sheets, or a database node. Validate email and phone fields, then update the record with deliverability, phone type, risk, and match status.
Enrich incomplete leads
Use Append Email or Append Phone when you have name and address data but missing contact fields. Continue only when the response indicates a match and your internal compliance rules allow contact use.
Enrich B2B contacts
Use Enrich Email when you have a person’s name and company domain but need a likely work email. Use Find Mobile when you have a professional profile URL, work email, or personal email and need mobile number enrichment.
Analyze domains
Use Analyze Domain SEO to collect authority, backlink, traffic, and trust signals for lead scoring, partner review, marketplace checks, or domain intelligence workflows.
Research search intent
Use Look Up Search Intent to retrieve web search intelligence such as organic result data, knowledge graph data, people also ask, and related searches.
Output
By default, the node returns the full 1Lookup API response, including fields such as:
successdata.requestdata.metadatadata.risk_assessmentdata.classificationdata.insightsdata.recommendationsEnable Simplify Response to return only the nested data object when the API response contains one. This is useful when mapping fields into later n8n nodes.
