LinkedIn API Without Login: Access Public Data Without OAuth

If your workflow needs structured public professional or company data—not access to a member’s private LinkedIn account—you do not need to build an end-user LinkedIn OAuth flow. EnvoAPI lets server-side applications retrieve supported public profile, company, search, job, and post data using an API key.

EnvoAPI is an independent third-party API and is not affiliated with or endorsed by LinkedIn.

What Does “Without Login or OAuth” Actually Mean?

“Without login” means your users do not need to complete a LinkedIn sign-in or consent flow inside your application. It does not mean requests are unauthenticated or that private LinkedIn data becomes available.

No end-user LinkedIn sign-in flow

A public-data enrichment workflow with EnvoAPI does not require your application to:

• Redirect users to LinkedIn
• Ask users to sign in to LinkedIn within your app
• Display a LinkedIn consent screen
• Receive an authorization code
• Exchange that code for a LinkedIn access token
• Store refresh tokens or manage token expiry

LinkedIn’s official APIs use OAuth 2.0 for application and member authorization. A member-authorized integration requires the member to grant permission before an app accesses member resources or acts on that member’s behalf.

It does not mean “no authentication”

Every EnvoAPI request still requires authentication through the X-API-Key header. Store that key in an environment variable or secrets manager, and call the API only from server-side code.

Security note: Browser applications should send requests to your own backend route. That backend route then calls EnvoAPI with the secret API key. Do not expose API keys in frontend bundles, mobile clients, repositories, logs, analytics tools, or error messages.

It does not include private data

No LinkedIn OAuth flow does not mean access to private account data, member-authorized information, or the ability to act on behalf of a LinkedIn member.

Use an official LinkedIn API when your product requires member identity, explicit consent, publishing, advertising, Page management, or permissions granted by a member or administrator. Use EnvoAPI when your workflow needs supported public-data enrichment through a server-side API.

How EnvoAPI Makes the Request Work

EnvoAPI converts a public identifier or search input into structured JSON that your application can map into a CRM, recruiting system, database, or market-research workflow.

Pass a public identifier

Choose the input based on the entity your workflow already knows:

For example, a sales workflow can submit a company domain such as example.com. A recruiting workflow can submit a public professional profile URL. A research workflow can begin with a people or company search query.

Authenticate once with your API key

The request flow has 3 steps:

1. Your backend receives a profile identifier, profile URL, company domain, or search query.
2. Your backend sends an HTTPS request to the appropriate EnvoAPI endpoint with X-API-Key.
3. EnvoAPI returns structured JSON that your application maps to the fields required by the workflow.

See the EnvoAPI developer documentation for API conventions, response envelopes, pagination, and endpoint behavior.

Receive normalized data

Structured JSON reduces manual parsing across profile, company, search, job, and post workflows. Your application can validate the input, retrieve the data, select only the fields it needs, and write those fields into a CRM or internal system.

Returned fields depend on the endpoint, supplied identifier, and public availability of relevant information. A successful request does not guarantee that every possible field exists for every record.

What Public Data Can the API Return?

EnvoAPI supports public-data workflows for professional profiles, companies, searches, jobs, and posts. Coverage varies by endpoint and by publicly available data.

Profile data

Supported profile enrichment can include:

• Name, headline, and public profile attributes
• Work experience and education
• Skills and certifications
• Publicly available contact details
• Public activity or post-related data where supported

Use the profile API reference to confirm the required parameters and response codes for a profile URL request.

Company data

Company enrichment workflows can include:

• Company identity and firmographic attributes
• Employee and employee-associated records
• Products, public posts, and open roles
• Company insights based on the selected endpoint
• Lookup inputs such as domain, slug, URL, or company ID

Example: A B2B SaaS team can use a company domain to enrich an account record before routing it to an account executive.

Search, job, and post data

When your workflow does not begin with a known profile or company, EnvoAPI also supports endpoint families for:

• People and company search
• Job data
• Public post data

Review the full API reference before implementation to verify supported inputs, response fields, rate limits, and status codes for the endpoint you select.

What Does an Actual API Request Look Like?

Keep the API key on the server and use a public identifier that matches the endpoint’s requirements.

Example: Retrieve a public professional profile

1curl --request GET \2  --url "[https://api.envoapi.com/api/v2/profiles/{public_identifier}](https://api.envoapi.com/api/v2/profiles/{public_identifier})" \3  --header "X-API-Key: $ENVO_API_KEY"

Replace {public_identifier} with the relevant public identifier. Set $ENVO_API_KEY as a server-side environment variable, then execute the request from a backend service, serverless function, or secure API route.

For a full LinkedIn profile URL, EnvoAPI also provides a profile-detail endpoint that takes the URL as a query parameter.

Example: Enrich a company from its domain

1curl --request GET \2  --url "[https://api.envoapi.com/api/v2/companies/by-domain?domain=example.com](https://api.envoapi.com/api/v2/companies/by-domain?domain=example.com)" \3  --header "X-API-Key: $ENVO_API_KEY"

After receiving a company response, your workflow can map approved fields into an account record or use the resulting company context to support subsequent employee and profile research.

Handle responses safely

• Validate the profile identifier, URL, or domain before sending a request.
• Store only the fields your business workflow requires.
• Treat HTTP 401 as a missing or invalid API key issue.
• Never log, return, or expose the API key to the client.

Official LinkedIn API vs. EnvoAPI

The right option depends on whether your application needs public-data enrichment or member-authorized LinkedIn functionality.

Choose EnvoAPI for public-data enrichment

Choose EnvoAPI when your backend needs to turn public profile, company, job, search, or post inputs into structured data for sales intelligence, CRM enrichment, recruiting, or market research. This workflow does not require access to a private account or action on a member’s behalf.

Learn more about how EnvoAPI is positioned.

Choose official APIs for user authorization

Choose official LinkedIn APIs when your product requires a LinkedIn sign-in, permissions granted by a member or administrator, official API product access, or actions performed on behalf of a LinkedIn user.

Before deployment, compare plans, credits, and rate limits to match your expected enrichment volume to the appropriate API plan.
