\Recurly_Purchase::invoice always returns this:

This is my code:

Yeah that error is frustratingly vague. You don't say what version of the client you're using but the issue is due to this change:

• Changed POST /v2/purchases request:
  • <currency> tag no longer allowed under <adjustment>. <currency> is an invoice level tag and is not permitted under an adjustment.

Which changed in the 2.8 version of the API but it looks like we didn't list that as a breaking change in the 2.9.0 client release notes.

Apologies for that. I'll get the release notes fixed and open up a ticket to see if we can get a more helpful error message coming back out of the API.

Oh since I didn't say it explicitly, you should just be able to remove this line:

$charge->currency = $data['currency'];

And get things working.

It worked! Thank you @drewish
