ZoomInfo is a B2B database and intelligence platform that provides contact and company information for sales and marketing teams. With the Relevance AI ZoomInfo integration, your AI agents can search ZoomInfo’s database and enrich records with detailed contact and company data using ZoomInfo credits. Two integration methods are available: the ZoomInfo GTM (OAuth) integration, recommended for new setups, and the legacy credential-based integration for existing users. Both can coexist as separate providers in your Relevance AI workspace, so you can run them in parallel if needed.
The ZoomInfo integration in Relevance AI was built by Relevance AI, and is therefore supported by our team, not ZoomInfo. If you have a question or issue with using ZoomInfo in Relevance AI, please reach out to our support team. If you have a question or issue that is only about ZoomInfo, you can reach out to ZoomInfo support directly.

​
Connect the integration

The ZoomInfo GTM OAuth integration is in early access. Contact your Relevance AI account team to enable it for your workspace.
The GTM integration connects your ZoomInfo account through OAuth. Token refresh is handled automatically — no credential management required after the initial sign-in.
1

Open the Integrations page in Relevance AI

Go to Integrations & API Keys in the sidebar of your Relevance AI dashboard.
2

Select ZoomInfo GTM

Find and click on ZoomInfo GTM from the available integrations list.

4

Sign in to your ZoomInfo account

A browser window will open. Sign in to your ZoomInfo account and authorize Relevance AI to access your data.
5

Confirm the connection

Once authorized, your ZoomInfo GTM account will appear as a connected integration. Access is managed through OAuth tokens that refresh automatically.

​
Legacy (credential-based)

For new setups, use the ZoomInfo GTM OAuth integration described above. The credential-based integration remains fully supported for teams already using it.
The legacy integration uses credential-based authentication. You will need three values from your ZoomInfo account: your ZoomInfo email address, a client ID, and a private key.
1

Find your ZoomInfo API credentials

Log in to your ZoomInfo account and navigate to the API settings or developer portal. Locate your Client ID and Private key. These are generated in your ZoomInfo account under the API or integrations section. If you do not see them, contact your ZoomInfo account administrator.

Keep your private key secure. Do not share it publicly or commit it to version control. If your private key is compromised, regenerate it from your ZoomInfo account settings.

​
Understanding credit consumption

ZoomInfo uses a credit-based system for data enrichment. It is important to understand which operations are free and which consume credits before building your workflows.

​
Free operations

Searching does not consume ZoomInfo credits. The following operations are free:
  • Searching for contacts by name, title, company, location, or other criteria
  • Searching for companies by name, industry, size, location, or other filters
  • Browsing and filtering ZoomInfo’s database to build prospect lists
  • Looking up taxonomy values (industries, job functions, seniority levels)

​
Credit-consuming operations

Enrichment operations consume ZoomInfo credits. Credits are used when you retrieve detailed data for a specific record, including:
  • Email addresses
  • Phone numbers
  • Company revenue figures
  • Employee counts
  • Other detailed contact and company attributes
The integration includes built-in credit safeguards to help prevent unexpected credit usage. Monitor your credit balance in your ZoomInfo dashboard and design workflows to enrich only when necessary.
Use search operations to filter and qualify prospects first, then enrich only the records that meet your criteria. This approach minimizes credit consumption.

​
Tools & tool steps

ZoomInfo provides two sets of tool steps corresponding to each integration method. GTM tool steps require a ZoomInfo GTM (OAuth) connection; legacy tool steps require a credential-based connection.

​
GTM tool steps (OAuth)

These tool steps require a ZoomInfo GTM (OAuth) connection. See the GTM connection setup above.

​
Search and enrichment

Search contacts (GTM)

Search for contacts by criteria such as job title, company, location, or industry. Does not consume credits.

Enrich contacts (GTM)

Retrieve detailed contact data including email addresses, phone numbers, and professional details. Consumes credits.

Search companies (GTM)

Find companies matching filters like industry, employee count, revenue range, or location. Does not consume credits.

Enrich companies (GTM)

Retrieve detailed company data including revenue, employee count, and firmographic details. Consumes credits.

​
Taxonomy lookup

Taxonomy lookup

Browse ZoomInfo’s taxonomy to discover valid filter values for industries, job functions, and seniority levels. Use this step when building search queries to find the exact values ZoomInfo recognizes, so your filters return accurate results. This step does not consume credits.

​
Advanced API access

ZoomInfo GTM API call

Make custom API calls to any ZoomInfo GTM endpoint for advanced use cases not covered by the pre-built steps.

​
Legacy tool steps (credential-based)

These tool steps require a ZoomInfo credential-based connection. See the legacy connection setup above.

​

How to add ZoomInfo tool steps to your agent

  1. Create a new tool in your Relevance AI workspace or open an existing one.
  2. Scroll down to Tool steps.
  3. Search for “ZoomInfo” in the tool step search bar.
  4. Select the desired ZoomInfo action.
  5. Select your connected ZoomInfo account from the dropdown (choose your GTM or legacy account depending on the step).
  6. Configure the action parameters and connect the tool to your agent.

​
Use the ZoomInfo API Call tool step (advanced)

​
ZoomInfo GTM API Call

Advanced users can make custom API calls to any ZoomInfo GTM endpoint using the ZoomInfo GTM API Call tool step.
1

Create or open a tool

Create a new tool in Relevance AI or open an existing tool you want to add ZoomInfo functionality to.
2

Add the ZoomInfo GTM API Call tool step

Scroll down to Tool steps, search for “ZoomInfo GTM API Call”, and add it to your workflow.
3

Select your ZoomInfo GTM account

Select your connected ZoomInfo GTM (OAuth) account from the dropdown.
4

Configure the API endpoint

Set the HTTP method, endpoint path, and request body parameters according to the ZoomInfo API documentation.
5

Test your configuration

Test your API call before deploying to confirm it returns the expected data.
{
  "endpoint": "/search/contact",
  "method": "POST",
  "body": {
    "searchField": [
      {
        "fieldName": "jobTitle",
        "value": "VP of Sales"
      }
    ],
    "rpp": 10,
    "page": 1
  }
}
This call searches for contacts with the job title “VP of Sales” and returns up to 10 results. Search calls do not consume ZoomInfo credits.

​
ZoomInfo API Call (legacy)

Advanced users can make custom API calls to any ZoomInfo endpoint using the ZoomInfo API Call tool step.
1

Create or open a tool

Create a new tool in Relevance AI or open an existing tool you want to add ZoomInfo functionality to.
2

Add the ZoomInfo API Call tool step

Scroll down to Tool steps, search for “ZoomInfo API Call”, and add it to your workflow.
3

Select your ZoomInfo account

Select your connected ZoomInfo (credential-based) account from the dropdown.
4

Configure the API endpoint

Set the HTTP method, endpoint path, and request body parameters according to the ZoomInfo API documentation.
5

Test your configuration

Test your API call before deploying to confirm it returns the expected data.
{
  "endpoint": "/companies/enrich",
  "method": "POST",
  "body": {
    "company_name": "{{input.company_name}}",
    "domain": "{{input.domain}}",
    "include_attributes": ["industry", "revenue", "employee_count", "technologies", "location"]
  }
}
This call retrieves specific company attributes for use in lead qualification. Note that enrichment calls consume ZoomInfo credits.

​
Example use cases

Build a GTM agent that searches ZoomInfo for companies matching your ideal customer profile, then enriches only the top-scoring matches with detailed contact and company data. The agent can prepare outreach briefs and route leads to the appropriate sales representatives.
Create an agent that first searches ZoomInfo to filter and qualify leads based on free criteria (company size, industry, location), then enriches only the records that pass qualification with email addresses and phone numbers. This pattern keeps credit usage low while maximizing data quality.
Deploy an agent that searches ZoomInfo for decision-makers at target accounts, enriches their contact details, and compiles account briefs for your marketing team without consuming credits on records outside your target list.
Build an agent that identifies incomplete records in your CRM and uses ZoomInfo to fill in missing email addresses, phone numbers, and company details. Implement logic to skip records that already have complete data to avoid unnecessary credit consumption.
Use the Taxonomy Lookup step to retrieve valid industry codes or seniority levels, then feed those values into a Search Contacts (GTM) or Search Companies (GTM) step. This pattern ensures your filters match ZoomInfo’s accepted values and improves search accuracy.

​
Best practices

For new setups, use the ZoomInfo GTM (OAuth) integration. It handles token refresh automatically, requires no private key management, and uses the same tool step pattern as other OAuth-based integrations in Relevance AI. Keep the legacy credential-based integration if you already have it configured and working — there is no need to migrate unless you want to.
Use search operations to filter your prospect pool before enriching. Only enrich records that meet your qualification criteria, and implement checks to avoid enriching the same record twice. Monitor credit usage in your ZoomInfo dashboard and set up alerts if available.
Store your ZoomInfo client ID and private key securely when using the legacy integration. Do not hard-code credentials in tool configurations visible to other team members. Rotate your private key if you suspect it has been compromised. The GTM OAuth integration avoids this concern entirely since no credentials are stored.
Only use ZoomInfo data for legitimate business purposes. Comply with GDPR, CCPA, and other applicable privacy regulations in your region. Review ZoomInfo’s terms of service and acceptable use policy before building automated outreach workflows.

​
Frequently asked questions (FAQs)

The GTM integration uses OAuth to connect your ZoomInfo account. You sign in once and Relevance AI manages token refresh automatically — no credential storage or rotation required. The legacy integration uses PKI/JWT credentials (email, client ID, and private key) that you generate from your ZoomInfo API settings and paste into Relevance AI. Both integrations give you access to ZoomInfo’s search and enrichment capabilities, but the GTM integration is simpler to set up and maintain for new users. The tool steps available also differ between the two — GTM tool steps include the Taxonomy Lookup step and updated search/enrich steps, while legacy tool steps use the original credential-authenticated endpoints.
The ZoomInfo GTM OAuth integration is available to ZoomInfo customers with GTM Intelligence access. If you are unsure whether your ZoomInfo account supports the GTM OAuth flow, check with your ZoomInfo account manager before setting up the integration in Relevance AI.
The Taxonomy Lookup step lets your agent browse ZoomInfo’s reference taxonomy — the set of accepted values for fields like industry, job function, and seniority level. When building search queries, using exact taxonomy values improves match accuracy. For example, instead of passing “tech” as an industry filter, you can first run Taxonomy Lookup to get the correct industry code, then use that value in a Search Companies (GTM) step. Taxonomy Lookup does not consume ZoomInfo credits.
Yes. The GTM (OAuth) and legacy (credential-based) integrations exist as separate providers in Relevance AI, so you can connect both and use them in different tools or workflows. GTM tool steps will always prompt you to select a GTM account, and legacy tool steps will prompt for a credential-based account. There is no conflict between the two.
It depends on the operation. Search operations are free — searching for contacts or companies does not consume ZoomInfo credits. Enrichment operations consume credits — retrieving detailed data such as email addresses, phone numbers, revenue figures, or employee counts for a specific record uses credits. Design your workflows to search first and enrich only when needed.
You need three credentials from your ZoomInfo account: your ZoomInfo email address, a client ID, and a private key. These are available in the API or integrations section of your ZoomInfo account settings. Contact your ZoomInfo account administrator if you do not have API access.
Yes. Both the ZoomInfo GTM (OAuth) and legacy integrations are compatible with GTM agents in Relevance AI. You can use ZoomInfo search and enrichment tool steps in GTM agent workflows.
Enrichment operations will fail when your ZoomInfo credit balance is exhausted. Search operations will continue to work since they do not consume credits. Monitor your credit balance in your ZoomInfo dashboard and top up as needed. The integration includes built-in credit safeguards to help prevent unexpected over-usage.
Yes. You need an active ZoomInfo account to connect either integration. For the GTM (OAuth) integration, you also need a ZoomInfo account with GTM Intelligence access. For the legacy integration, you need API access and valid API credentials (email, client ID, and private key).
