Assign the business address to blank transactions

Assign the organization's own business address to its selected blank-address transactions and re-queue validation. Ids that are not (or no longer) blank-eligible are ignored and reported. `certified` must be `true`. Returns `businessAddressMissing: true` (assigning nothing) when the organization has no business address configured. Owner/Admin only: 403 if your credential may read the organization but is not permitted, 404 if you do not own it, and 400 if `certified` is not set.

Category: Addresses

Request body:
transactionIds (string[], required) - Ids of the blank-address transactions to assign the business address to.
certified (boolean) - Must be `true` to certify the assignment; the request is rejected otherwise.

Response fields:
updated (integer, required) - Transactions the business address was assigned to.
skippedNoBusinessAddress (integer, required) - Eligible transactions skipped because the organization has no business address configured.
failed (integer, required) - Transactions whose address write failed.
ignored (integer, required) - Requested transactions dropped because they were not (or no longer) blank-eligible.
businessAddressMissing (boolean, required) - `true` when the organization has no business address configured, so nothing was assigned. Set one and retry.

Response statuses: 200, 400, 401, 403, 404, 409, 422
