API Specifications

To search for credit cards, you should set productTypes to ["credit_card"] on the lead and make requests to: https://api.engine.tech/leads/rateTables

If you have already created a lead and have a lead UUID, you can make requests to: https://api.engine.tech/leads/:leadUuid/rateTables

Passing PII (e.g., name, address, annual income, DOB) into the request allows leads to be evaluated for credit cards through the issuer's underwriting evaluations and receive personalized offers. As PII is added to the lead, Engine and its partners may return, either or both, personalized offers (with a higher probability of issuer approval) and ITA offers.

In the simplest case, you need only include "productTypes": ["credit_card"] in the request body to return some ITA credit card offers (identified by isITA: true).

For more information, see the official API documentation:

Credit Card Response

Partners building a Native API integration must make a secondary request to Engine’s API to retrieve offer information. Below are instructions for this secondary request:

• Capture the uuid returned in the initial API response (please note: uuid is distinct from leadUuid - uuid denotes the Rate Table UUID)

• Execute a GET request to Engine’s Offers Endpoint: https://api.engine.tech/originator/rateTables/:uuid

• Poll the endpoint once every second until pendingResponses is empty (may take up to 15 seconds)
