Indented goal is to send data from a quite large csv file to an external API without running into rate limits or throttling. To be precise; all API POST request need to “simulate” live traffic (as if every submit is not sources from the bulk file, rather submissions on a live website. Trying to figure out how to implement this “mimic real user behavioir”. 

can anyone please help me?

Hi @Tal 

You can use Zapier Transfer ( to send your data in bulk. To do this:

  • Put your CSV data in a Google sheet
  • Using transfer, select ‘Webhook by Zapier” as destination to make POST request to any endpoint

However, that is likely to hit a limit. The other way of doing this would be a bit complicated, which is as follows:

  • Save your CSV as JSON in a publicly accessible URL

  • Use “Webhook by Zapier” to GET the JSON data from the URL
  • Use “Loop by Zapier” to go take one item/array from the CSV/JSON data
  • Use “Delay” action to avoid rate limit
  • Use “Webhook by Zapier” to make POST request to your website where you can specify the submission
