Endpoint
email and session_id. Reusing the same session_id updates the existing lead for your tenant instead of creating a duplicate.
Set
session_id to the same value you send to the current Card Submit or Widget checkout as partnerSession. This allows Paysight to mark the lead paid when the successful transaction webhook arrives.Authentication
Generate API keys from Tools → Customer Leads → API endpoint in Platform. Full keys are shown after generation so you can copy them. If a key is lost, generate replacements and update every client because the previous keys stop working immediately.Browser
Use the publishable key generated in Platform. The browser origin must exactly match one of the configured allowed origins.Server
Use the secret key as a Bearer token. Never expose this key in browser code. Reading leads withGET requires this server-only key; publishable browser keys are write-only.
Example
201 Created; updates return 200 OK. API clients cannot set tenant_id, status, or payment fields.
Query leads
Use exact query parameters withGET. Supported filters are id, email, session_id, transaction_id, subscription_id, and status. You can combine filters; all supplied filters must match. Results are ordered by the most recently updated lead and limited to 50 by default or 100 maximum.
session_id when you need one specific journey.
Paid records include the transaction, order, application, amount, currency, and subscription identifiers captured when that lead first became paid. This links the lead to the converting payment; it is not a history of every later recurring transaction.
A customer lead is a checkout journey, not a canonical customer profile. Paysight does not currently infer a one-to-one customer relationship from email. If your system needs a permanent customer identity across sessions, keep that mapping in your customer system and use the returned lead, session, transaction, or subscription identifiers.
Paid lead webhooks
When a configured successful transaction matches the tenant, application ID, environment, andsession_id, Paysight changes the lead to paid and sends a customer_lead.paid webhook. See Customer lead integration for configuration, payload signing, retries, and verification.
