did you check it have to be sent as parameter or in header?

By the way, where did you get it? I am still trying to get and try it

were you able to submit the invoice? No matter how I try, only get the message: "The authenticated TIN and documents TIN is not matching"

Good day!
Wanna check with you all. How long do you get a reply from myinvois after sending the email requesting for ID and secret?
I have not got any reply after 1 day, and wanna know if that is normal.
If need to follow up, anyone knows how to check with them?
Thanks a lot!

i have same issue, but using the same TIN not fixed the issue.

Yup, I can confirm our TIN same as what we registered with IRB, but still having same issue.

Even try to validate TaxPayer's TIN also having issue. You may try from your side, that BRN number is legit.

you have to perform HTTP POST rather than GET
i think you have to get the access token before trying to validate TIN

yup, the token already passed.
