Using my valid API key, my attempt to register a domain on Mailgun returns invalid parameter errors. Do I need an existing SMTP password?

import requests

def register_mail_domain(api_secret, domain_label, smtp_key):
    url = "https://api.mailgun.net/v3/domains"
    payload = {"name": domain_label, "smtp_password": smtp_key}
    response = requests.post(url, auth=("api", api_secret), data=payload)
    return response.json()

print(register_mail_domain("secure_api_key", "newdomain.example.net", "new_smtp_secret"))

I once faced a similar problem when experimenting with Mailgun’s API. I discovered that the issue often wasn’t with the API key or SMTP password but rather with parameter naming, which can be quite sensitive. The documentation can be sparse at times and easy to misread. After a careful review, I realized that using the correct field names and ensuring the proper values resolved the errors. It’s important to double-check the latest API documentation since even a minor deviation in parameter names can result in an invalid parameter error.

During my troubleshooting with Mailgun’s API, I encountered similar issues. I learned that the problem often stems from minor discrepancies in parameter names rather than the absence of an SMTP password. Although I initially suspected authentication, I later found that the API expects very specific field names and data types, which might differ from older versions of the documentation. A close review of the latest docs was vital in resolving the error. Ensuring that all parameters exactly match the expected format was the most effective solution I discovered for this issue.

hey, i had a similar hassle. turning out, a tiny typo in the field names was the culprit. double-check you domain formt and api keys as per latest docs. a minor mispelling can easily cause those invalid parametrs error, trust me!
