Why am I receiving "HTTP 429 - Too many request / throttling" response from API ?

[#1]

The following table shows the current throttling configuration that we have in place.

Name	Policy	Applies to	Description	Interval	Limit
Test Client Limit	IntervalLimit	Test API Clients	Hourly number of requests per company reached	1 Hour	500 requests
The SameRequest Limit	SameRequestLimit	All API clients	The same request made too many times	1 Minute	5 requests
Client Error Limit	ClientErrorLimit	All API clients	The Same request failed already	5 Minutes	2 requests
Live-Production API Client Limit	TenantIntervalLimit	Live-Production API Clients	Hourly number of requests per company reached	1 Hour	15000 requests
Visma Connect Auth	CompanyIntervalLimit	Live-Production API Clients	Hourly number of requests per company reached	1 Hour	15000 requests
Swagger Client Request Limit	TenantIntervalLimit	Swagger-ui client	Hourly number of requests per company reached	1 Hour	500 requests

As of today,
500 transactions/calls allowed per company, per hour during the testing phase for Test Type API Clients.

After completing the testing phase, you should contact your partner service (How to contact), informing them with your Redirect_URI to obtain Live - Production type API Client .
