Approve Transaction

Approve Transaction

post

In this endpoint, enter the exact same values that were used when creating the transaction (for example, max_fees must be the exact same values).

You can retrieve transactions "pending approval" with GET /transactions?status=PENDING_APPROVAL.

However, you should NOT trust those values and you should implement your own source of trust.
