API Co-Signer helps users automate approval and signing processes, making it ideal for workspaces with high transaction volumes or frequent activities. If you’re looking to automate transactions, it’s the perfect solution.
  • Before signing a transaction, Co-Signer will callback to your business system. It can initiate the signature only after authorization is obtained; otherwise, the transaction cannot proceed.
  • After the app-side signature authorization for the consolidation transaction, it will not callback to the Client system.
