Fetch (Poll) Offer & Hand-Off Link
Take the borrower from choosing an offer to continuing their application. Using the selected offer and the same journey ID, retrieve the offer details and a secure link to Aarthik Labs' Hosted Experience.
Open the link to guide the borrower through the next steps for their chosen lender, such as verification, required documents and agreements. Your experience handles discovery and selection, while the Hosted Experience helps the borrower continue the selected application.
Authentication
Send Authorization: Bearer <PLATFORM_API_KEY> from a trusted back-end.
Path parameters
Stable borrower identity from the partner system. Keep a 1:1 mapping between the borrower and borrowerProviderID across sessions and application attempts to preserve resume, history, and post-disbursal continuity.
Offer identifier returned in data.lenders.<lenderName>.offers[].offerID.
Headers
Optional caller-supplied trace identifier. When omitted, the API generates one and mirrors it as correlation_id.
Query parameters
Journey ID returned as data.journey.id by Start. Send this on Offers and Hosted handoff calls to continue the intended application attempt. The journey_id query parameter and x-aarthiklabs-journey-id header aliases are also accepted. If more than one alias is sent, all values must match.
Deprecated compatibility parameter. Its value is ignored; Aarthik Labs server configuration determines the effective offer-acceptance decision.
