FAQ
Where do I get the Pull API key? In IndiaMART Lead Manager, the three-dot menu > Import/Export Leads > Pull API > Generate Key. It is for paid sellers with the Leads API add-on. Keep it secret.
Can I use it without giving my key to anyone? Yes. Open the Pull API URL in your own browser and save the answer as a .json file, then attach that.
Will it keep my notes when I add new leads? Yes. Download your sheet as CSV and pass it with --master.
