Exact Online is notorious for its API limitations. If these limits are reached, the API throws HTTP 429 - Too Many Requests. More information about such limitations can be found in [Exact Knowledge Base](https://support.exactonline.com/community/s/knowledge-base#All-All-DNO-Simulation-gen-apilimits).&nbsp;  
A possible workaround is setting two connection properties (_MaximumRequestRetries_ and _RetryWaitTime_) through the _Other_ property in the driver configuration, to tweak how the retry logic works.

- _MaximumRequestRetries_ is the maximum number of times to retry a request if we get the error, while

- _RetryWaitTime_ is how long to wait before retrying a request in milliseconds.

Below is a screenshot that demonstrates how to set these properties and their corresponding values:

The other recommendation would be to use a [custom OAuth App](https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fcdn.cdata.com%2Fhelp%2FDYJ%2Frssis%2Fpg_oauthcustomappcreate.htm&data=05%7C01%7Csupportsent%40cdata.com%7C25d8b4c03f644ed3078908db7ba22114%7Cbf6e4267a9fb419bae7b7586fab0ff66%7C1%7C0%7C638239708547820011%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=e8tmnsJItApP1C3hqofWgUlX%2FqJYyfaqtADFyJ6cEMA%3D&reserved=0) since our embedded app has a much smaller API limit.
