This APIs will be used by my other application. 1) Authentication API This API can be accessible at [login to view URL] - Other application will call this api and give this api username and password as input. This api will confirm with zendesk if username and password is valid and return success or failure message with error info back to other appplication. 2) Create request api This API can be accessible at [login to view URL] - Other application will call this api and give all required fields for creating ticket as input.
