API rate limit - 429 error

[Matsuirs]

Im using Droppery API for product syncing.

But some products are not synced.

I see in the error logs that there is a rate limit issue (error 429).

So either your rate limits are very low.

Droppery connection works perfectly with Shopify/
In this case, you can see that some products come in your shop, some don't.
If we look in the error logs, we see a 429 which is actually saying that there is a rate limit or hosting issue. This is a error from Shopify, not from Droppery. 

Please i need help to increase rate limits for product syncing. How i can do that?
