End-to-end company lifecycle (CRUD)

Manage the full lifecycle of business listings programmatically:

Create: POST /order: create/order a new company
Read: GET /search, GET /details: discover and enrich profiles
Update: PUT /update: keep data current (hours, attributes, etc.)
Delete/Suppress: POST /suppress, DELETE /cancel: handle suppression and matching cancellation

Sample flow (curl)

# 1) Create
curl -s -X POST -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
  -d '&#123;"name":"New Co Ltd","countryCode":"GB"&#125;' \
  "https://api2.cylex-international.com/order?Token=$TOKEN"

# 2) Read
curl -s -H "Authorization: Bearer $TOKEN" \
  "https://api2.cylex-international.com/search?Name=New%20Co%20Ltd&CountryCode=GB"

# 3) Update
curl -s -X PUT -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
  -d '&#123;"id":"GB-123456","description":"Updated description"&#125;' \
  "https://api2.cylex-international.com/update?Token=$TOKEN"

# 4) Suppress/Cancel
curl -s -X POST -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
  -d '&#123;"listingId":"GB-123456","suppress":true&#125;' \
  "https://api2.cylex-international.com/suppress?Token=$TOKEN"

curl -s -X DELETE -H "Authorization: Bearer $TOKEN" \
  "https://api2.cylex-international.com/cancel?CountryCode=GB&id=GB-123456&Token=$TOKEN"
