This ensures that you do not overload Mapp Cloud API servers and minimize occurrences of failure responses. ### One API call per type at a time Ensure that you poll different response types when polling in parallel. Parallel same-type requests are not supported. ### Retrieve responses regularly The Response Queue service stores events for the previous 30 days. After this time, old responses are overwritten.
