Before I go down a rabbit hole, is it possible to use

form.addCredentialField()

, store the GUIDs in a custom record, and then use those GUIDs somehow with a basic authorization header in

<http://https.post|https.post>()

?

yes

I'm trying but my auth is failing. What does `https.post({credentials:myCreds})`actually add to the request?

I heavily recommend base 64 encoding the username and password combination before entering it in the credential field

I'll try that

Other than that, use a echo service like httpbin.org to see what headers netsuite is sending out

that's the one. thanks @battk

webhook.site is another one I like
