Data decays over time. Phone numbers change, people move jobs, companies relocate. Stale data kills conversion rates and wastes rep time.
Manual database updates don't scale. An application programming interface (API) for data enrichment keeps your CRM accurate without burning hours on research and data entry.
What Is the ZoomInfo Enrich API?
The ZoomInfo Enrich API is a programmatic interface that automatically appends verified contact and company data to records in your CRM, marketing automation platform, or custom application. It eliminates manual data entry and keeps records accurate as prospects change jobs or contact details go stale.
The Enrich API serves as the data backbone for sales, marketing, and RevOps workflows. Instead of manually researching contacts or letting records decay, you can automate data enrichment at the point of record creation or on a scheduled cadence.
The ZoomInfo Enrich API enables teams to:
Fill missing fields: Append direct dials, verified emails, and job titles to incomplete records
Refresh stale data: Update records when contacts change roles or companies
Standardize messy data: Normalize company names, industries, and locations for cleaner segmentation
Route leads accurately: Enrich inbound leads in real time for faster, smarter assignment
ZoomInfo API Types and GTM Workflow Fit
ZoomInfo publishes four API categories, each designed for different GTM workflows. The Enrich API sits within the Standard APIs category, but understanding the full portfolio helps you choose the right endpoint for your use case.
API Type | Primary Use Case |
|---|---|
Standard APIs (Search, Enrich, Lookup) | Point enrichment, prospecting queries, single-record lookups |
Scaling APIs | High-volume batch enrichment for large database refreshes |
WebSights API | Identify companies visiting your website by IP |
Compliance API | Handle opt-out requests and privacy workflows |
Standard APIs for Search, Enrich, and Lookup
Standard APIs handle single-record or low-volume requests for prospecting and CRM enrichment. The three Standard API types serve distinct purposes:
Search: Query by firmographic or contact criteria to discover new prospects
Enrich: Pass in a partial record, get back complete contact and company data
Lookup: Retrieve a full profile using a known identifier (email, company domain)
Scaling APIs for High-Volume Enrichment
Scaling APIs are built for teams running large batch jobs, such as quarterly database refreshes or bulk list enrichment before campaigns. These APIs handle higher volumes efficiently through asynchronous processing.
Use Scaling APIs when you're enriching thousands of records at once. Use Standard APIs for real-time, single-record enrichment.
WebSights API for Visitor Identification
WebSights API resolves anonymous website traffic to company-level data. When a prospect visits your site, the API returns firmographic details so marketing can trigger account-based plays or alert sales to engaged accounts.
Compliance API for Privacy Workflows
The Compliance API handles opt-out requests and privacy regulations. Teams use it to automate suppression list management and ensure outreach respects contact preferences under GDPR, CCPA, and similar frameworks.
What Data Does the ZoomInfo Enrich API Return?
The ZoomInfo Enrich API returns verified contact data (direct dials, emails, job titles) and company data (firmographics, technographics, corporate hierarchy). You can pull this data programmatically:
Contact Data:
Direct dials: Mobile and direct phone numbers for decision-makers
Verified emails: Business email addresses with deliverability signals
Job titles and functions: Current role, department, seniority level
Employment history: Previous companies and positions for context
Company Data:
Firmographics: Industry, employee count, revenue range, headquarters location
Technographics: Technologies and tools the company uses
Corporate hierarchy: Parent companies, subsidiaries, and related entities
Funding and news: Recent investments, acquisitions, or company announcements
How to Integrate ZoomInfo Enrich with CRMs and Marketing Automation
The ZoomInfo Enrich API offers three integration paths: native CRM connectors, direct API calls with webhooks, and third-party middleware. Each path fits different technical environments and use cases.
Native CRM Enrichment with Salesforce, HubSpot, and Dynamics 365
ZoomInfo offers native integrations for Salesforce, HubSpot, and Microsoft Dynamics 365 that enrich records directly within your CRM without custom development. Native integrations support two enrichment modes:
Instant enrich: Enrich records as they're created in your CRM
Scheduled enrich: Batch refresh on a cadence (daily, weekly, monthly)
"We search and enrich data using the ZoomInfo APIs within our automated data prep, orchestration and routing layer to surface the most relevant accounts and contacts to reps in Salesforce." Red Sift
Direct API Enrichment with Webhooks
For teams with custom applications or data pipelines, the direct API path offers full control. You can call the Enrich endpoint programmatically and receive results via webhooks for asynchronous processing.
Webhooks are useful for high-volume or event-driven workflows where you need enrichment results delivered to a callback URL rather than waiting for a synchronous response.
Enrichment Workflows: Real-Time, Scheduled, and On-Demand
The ZoomInfo Enrich API supports three primary enrichment modes depending on your operational cadence:
Real-time enrichment: Trigger enrichment the moment a new lead or contact enters your system. Ideal for inbound lead routing where speed matters.
Scheduled enrichment: Run batch jobs on a cadence (weekly, monthly) to refresh existing records and catch job changes or company updates.
On-demand enrichment: Manually trigger enrichment for specific lists or segments before campaigns or outreach pushes.
Data Management with ZoomInfo Enrich: Deduplication, Normalization, and Leads-to-Accounts
The ZoomInfo Enrich API supports data management capabilities beyond field appends, helping RevOps teams maintain database hygiene at scale. Three core data management functions:
Deduplication: Identify and merge duplicate contact or company records to maintain a clean database
Normalization: Standardize inconsistent field values so "IBM," "I.B.M.," and "International Business Machines" resolve to a single entry
Leads-to-accounts mapping: Automatically associate incoming leads with the correct parent account for accurate routing and reporting
These capabilities support rules-based workflows for teams managing data quality at scale. ZoomInfo offers enrichment tiers (Enrich Essential, Enrich Premium, Enrich Premium+) with varying levels of these capabilities.
