Using Transaction Keys

The Transaction Key is used to specify transactions in requests that are sent to the Taxamo API.

It can be used with the following requests:

For example, if you want to confirm a transaction, you may use a POST method and an endpoint URL in the following format:



  • {Taxamo_A_URL} is the url of the Taxamo Assure environment.
  • {key} is the Transaction Key. It represents the specific transaction that you want to perform the request on.

Here is an example with a sample Transaction Key (PJyj7WQAAAAYTSOvTCmQLpBvs7KRe1lL6v3GSnQ):

curl --request POST \
  --url \
  --header 'content-type: application/json' \
  --header "x-marketplace-seller-token: $TOKEN" \
  --data '{}'
