Solid's ACH infrastructure supports Real-Time Authorization (RTA) on ACH Pull requests received as an RDFI. Refer to 2b in Types of ACH Transactions. It means, using the synchronous webhook, you can approve or decline ACH Pull requests in real-time.
Here is how it works:
- In the Solid Dashboard, configure the ACH RTA webhook endpoint for your program.
- When a Solid originated account receives an ACH Pull Request, you must approve or decline each Authorization.
Note: If Solid does not receive your approve or decline request within 2 seconds, the Authorization is automatically approved or declined based on your Stand-In Processing (STIP) settings.
