Auth method: Signed (HMAC) — this endpoint requires the full set of signed headers: x-access-id, x-request-id, x-timestamp, and an HMAC-SHA256 authorization signature. See Authentication.

The ledger transactions behind one of your payments. A payment can include a bridge hop that moves the funds to another chain, and a conversion that settles them. Each of those writes its own on-chain transaction, and those transactions don’t appear in your payment list. Results are oldest first. A payment with no internal transactions returns 200 with an empty data array. Transaction endpoints use the general limit of 120 requests per minute per merchant. See Rate limits.
