Professional Identity
LinkedIn Verification
Verify LinkedIn profile control through OAuth. Confirm professional identities for B2B transactions, hiring verification, or partnership validation.
How It Works
OAuth verification for professional networks
Step 1
Initiate OAuth
Call our API to get a LinkedIn authorization URL. User is redirected to LinkedIn's login.
Step 2
User Authenticates
User logs into LinkedIn and grants permission to verify their professional profile.
Step 3
Proof Generated
We verify the OAuth response and return a proof token with LinkedIn profile details.
API Integration
Integrate LinkedIn verification for B2B use cases
1. Create Verification Request
curl -X POST https://api.proof.holdings/api/v1/verifications -H "Authorization: Bearer pk_live_YOUR_API_KEY" -H "Content-Type: application/json" -d '{
"type": "social",
"channel": "linkedin",
"identifier": "john-doe-12345"
}'2. Verify the Proof Token
# After OAuth callback, check verification status
curl -X GET https://api.proof.holdings/api/v1/verifications/VERIFICATION_ID -H "Authorization: Bearer pk_live_YOUR_API_KEY"Response Example
