All endpoints are subject to the same rate limit, as they use the same authentication token x-abbiamo-seller-group-key. You can make up to 1,500 requests within a 5-minute window before exceeding the rate limit.
If this limit is reached, the API will return an HTTP 429 (Too Many Requests) error. To avoid it consider implementing delays if you think you might reach it.
All endpoint pages will have it displayed to remember the use about this limit
