post
https://staging-api.365finance.co.uk/prequalification/bulk

Requests a pre-signed S3 URL to upload a bulk pre-qualification data file. Once you have the upload URL, PUT your file bytes directly to S3 — no API key is needed for the S3 upload itself.

File size:

  • Files under 100 MB: a single uploadUrl is returned (uploadType: single)
  • Files 100 MB–200 MB: multipart upload URLs are returned (uploadType: multipart). Upload each part to its corresponding uploadUrl, collect the ETag from each S3 response header, then call POST /prequalification/multipart/complete.

Accepted file types: CSV, XLS, XLSX

Maximum file size: 200 MB
