TaxJar API for Marketplaces
If you are acting as a Marketplace (a platform for merchants to sell their products on), you can set up your sales tax collection to use the TaxJar API.
- We provide more information here for marketplaces in our Developer Guides.
We have worked with several marketplaces that have set up their sales tax collection using our API:
Some offer tax calculation services through a single marketplace API token and send in the calculations with addresses stored in your system.
- In this situation, you would need to use the "from_" address and "nexus_address" parameters because you'd need to store your sellers' nexus addresses in your system and send them into TaxJar when making a sales tax calculation request.
- We'd also recommend using the "from_" address because that will help ensure that the correct sourcing is applied to a Transaction when requesting a sales tax calculation; we explain more about sourcing here.
Others upsell TaxJar and allow their merchants to place a TaxJar API token in their account to set up tax calculations per their own TaxJar State Settings and then to push fulfilled order history into TaxJar for sales tax Reporting.
