Help With Stripe ACH, Plain Integration PHP

Hi there. I have some files from a developer who did a Stripe ACH integration for me in PHP. He did both options:

1) with Plaid (automatically verifying and connecting bank) and
2) without Plaid (using the 2 micro deposits method)

He did a great job and it looks like he stayed pretty consistent with all the code Stripe supplied. He just couldn’t figure out the final part, which is “pushing” (ie. withdrawing) money to a Customer’s Bank Account. I’ve read the documentation and it looks like. you use a combination of the Stripe Customer ID, the Customer’s bank token and some weird way they use an email address to initiate the “push” (ie. transfer).

I have his files that I can show you. I need someone who is confident they can do this and get it done for me.

Thanks!
