Quickstart

This walks you through sending a lead with a test key, then reading it back.

1. Create a test secret key

In your workspace, open Settings, API and integrations and choose New key. Pick type Secret and mode Test, and tick the scopes you need. Copy the key when it is shown. It is shown only once.

Test keys run the whole pipeline (checks, duplicates, spam rules) but write to a sandbox. You see their submissions on the key's page under Sandbox submissions.

2. Send a lead

Send a POST request with the lead's details. full_name is required, plus a phone number or an email, and consent must be true.

curl
curl -X POST "https://api.visaflow.work/v1/leads" \
  -H "Authorization: Bearer vf_test_xxxxxxxx_PASTE_THE_REST_OF_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{
  "full_name": "PW Sample Lead",
  "phone": "+919000000001",
  "email": "sample.lead@example.test",
  "country_interest": "CA",
  "visa_type": "student",
  "intake": "2027-09",
  "message": "Interested in a postgraduate diploma",
  "consent": true
}'
