​
Create or Update (PUT)

Use PUT /v1/topics instead of POST to perform an upsert. If a topic with the same fullyQualifiedName already exists, it will be updated; otherwise, a new topic is created. The request body is the same as POST. 
curl -X PUT "{base_url}/api/v1/topics" \
  -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/topics/bulk to create or update multiple topics in a single request. The request body is an array of create request objects. 
curl -X PUT "{base_url}/api/v1/topics/bulk" \
  -H "Authorization: Bearer {access_token}" \
  -H "Content-Type: application/json" \
  -d '[
    { "name": "topic_one", "service": "sample_kafka" },
    { "name": "topic_two", "service": "sample_kafka" }
  ]'
