API Documentation

Overview

The Sky Lane Network API follows the standard ping-post pattern used across the lead exchange industry. Sellers ping a subset of lead fields to check buyer interest and pricing, then deliver the full post to the buyer that accepted the ping. Buyers configure campaigns with acceptance criteria and receive pings and posts against those campaigns in real time.

Authentication

All requests require a bearer token issued to your account. Sandbox keys are prefixed sk_test_, live keys are prefixed sk_live_. Keys are scoped to either buyer or seller access.

Authorization: Bearer sk_live_51H8x...

Rate limits

Default limits are 120 requests/minute per key for ping/post endpoints and 30 requests/minute for read endpoints. Limits scale with campaign volume — contact your account manager to raise them. Rate-limited responses return 429 with a Retry-After header.

/leads/ping

Submitted by sellers to check buyer interest and pricing for a lead before delivering the full record. Only qualifying fields are required — never full PII — at the ping stage.

/leads/:lead_id

Returns delivery status, acceptance state, and return history for a previously posted lead.

  "lead_id": "ld_7c21ff",
  "status": "accepted",
  "returned": false,
  "return_reason": null
}

/campaigns

Lists active campaigns visible to your account, including vertical, geo, and price-band filters. Buyers use this to confirm live filter configuration; sellers use it to preview which of their pings are likely to be accepted.

{
  "campaigns": [
    {
      "campaign_id": "cmp_442",
      "vertical": "personal_loan",
      "states": ["OH", "IN", "KY"],
      "status": "active"
    }
  ]
}

Webhooks

Configure a webhook URL in your partner dashboard to receive asynchronous status updates. Payloads are signed with an X-SLN-Signature HMAC header.

Field dictionary

Common fields shared across verticals. Each vertical adds its own qualifying fields on top of this base set — the full dictionary per vertical is shared during onboarding.
