API reference / Record a connection's native-tax-disabled attestation

Record a connection's native-tax-disabled attestation

POST/connections/{conn_id}/attest

Record your confirmation that native tax collection is disabled on the connected platform, satisfying the native-tax L2 readiness check. A new attestation overwrites any prior one. Returns 400 if your credential has no associated email. Returns 404 if the connection does not exist, is archived, or belongs to an organization your credential cannot access. A multi-org credential must send an Organization-Id, Connection-Id or Entity-Id selector, or gets a 400.
