​
Overview

When building an integration to Zamp, this is the core workflow a business using your platform needs to be able to accomplish.

​
Endpoints Used

1

Building the Transaction Object

When a customer generates a Sales Order, populate the Transaction Object with transaction information.
2

Calculating Taxes

When the Sales Order is saved, make a POST request to the /calculations endpoint.
3

Retaining the Calculated Tax

The calculations endpoint will return a detailed breakdown of the taxes due (taxDue) for the transaction you have provided. Your system should retain the taxes due as this will be the liability owed for the transaction.
4

Posting the Transaction to Zamp

Provided that the transaction is finalized and the invoice is ready to be saved, make a POST request to the /transactions endpoint with the Zamp returned tax due (from step 3) in the taxCollected field.
