Create or Update (PUT)

Use PUT /v1/apiCollections instead of POST to perform an upsert. If an API collection with the same fullyQualifiedName already exists, it will be updated; otherwise, a new API collection is created. The request body is the same as POST.

curl -X PUT "{base_url}/api/v1/apiCollections" \
  -H "Authorization: Bearer {access_token}" \
  -H "Content-Type: application/json" \
  -d '{ ... same body as POST ... }'

PUT will not return a 409 conflict error if the entity already exists — it will update the existing entity instead.

Bulk Create or Update (PUT)

Use PUT /v1/apiCollections/bulk to create or update multiple API collections in a single request. The request body is an array of create request objects.

curl -X PUT "{base_url}/api/v1/apiCollections/bulk" \
  -H "Authorization: Bearer {access_token}" \
  -H "Content-Type: application/json" \
  -d '[
    { "name": "pet", "service": "sample_api_service" },
    { "name": "store", "service": "sample_api_service" }
  ]'

Error Handling
