Validation status
Implemented · fixture tested.
Implementation is checked against provider-shaped fixtures for every action, authentication failures, rate limits, pagination and duplicate safety. Provider sandbox and authorised account validation are recorded separately when credential-backed runs are completed.

tax estimates
- Calculate US sales taxDestinationNot retried automatically
Calculate an estimate without creating an order transaction. Reference is your local result identifier, not a TaxJar transaction ID.
Authentication
TaxJar API token
Plans and access
TaxJar account with API access. Token and subscription must permit API access; US calculations only in this connector.
Test environment
Use the sandbox token and sandbox origin; never reuse a live token for a test.
Rate limits
Respect TaxJar 429 responses and plan usage limits; estimates may consume billable API transactions.
Provider events
Not used by these operations. Nexra event triggers are not yet available; flows run on demand or on a schedule.
Before you build a flow
- Calculations require correct addresses, nexus, tax codes and amounts; Nexra does not determine tax liability.
- Estimates only: no tax filing, remittance, committed invoice or exemption management.
- Provider API usage can be billed. Calculations are never automatically retried.
- Credential-backed sandbox and production validation remain pending.
