API information READ ME
We encourage all of our customers to make use of our APIs to maintain data and to make sure that information is up-to-date. To ensure the scalability of our APIs while growing our customer and user base, we've decided to add restrictions on the usage of our SOAP APIs. These restrictions will be enforced programmatically, which means we will enforce a limit on concurrent calls per customer to 10. You should expect response code 429 if you happen to exceed this limit, and you are recommended to implement a backoff retry mechanism to handle the limit. Note that the limit applies to SOAP only. When moving from SOAP to Rest over the coming years, any limits will be built into the API.
