Question
I received an authentication (401) error when using your API.
Answer
Possible errors:
- Incorrect credentials (API key, project ID, etc.)
- Incorrect timestamp
- Our platform only accepts seconds, not milliseconds!
- Check your server time (most common cause of authentication error)
- Miscalculated dev_hash--please use formula md5(:unix_timestamp + :api_secret)
- If using shell script commands:
dev_hash=$(echo -n $timestamp$api_secret | md5)
If issue still persist, please contact support with the API header and call:
https://platform.api.onesky.io/1/projects/ :project_id /translations?
locale=en&
source_file_name=Localizable.strings&
api_key= :api_key &
timestamp= :unix_timestamp &
dev_hash=md5(:unix_timestamp + :api_secret)
A more comprehensive documentation of our API authentication method can be found here.

You saved my day, timestamp must be unix timestamp, who would thought. Sometimes is good to use brains :) thanks, me & my brains

When encountering an authentication error with an API, it often means that the provided credentials—such as an API key or access token—were incorrect, missing, or expired. To resolve this, double-check the API key or authentication token you’re using to ensure it’s valid and up to date. Make sure it has the required permissions and is correctly formatted according glitzyinfo to the API provider’s specifications. If you're storing this key in environment variables or a configuration file, verify that it’s being accessed correctly by your application.

hello thanks for sharing information related to API, some time ago i also having the problems with my painting website which is now solved
Authentication errors (like 401) can be tricky, especially with timestamps and hash calculations. If you’ve double-checked your credentials, server time, and hash formula but still face issues, it might help to review detailed troubleshooting steps. For example, this guide on DeepSeek API not working covers common fixes for similar API errors.
If the problem persists, sharing the exact request headers with support (as suggested) should help pinpoint the issue.
This support article would have saved me half a day of my life last month.
I was wrestling with a persistent 401 error and it was driving me absolutely mad. I must have checked my API key and secret a hundred times, convinced I had a typo. The
dev_hashlooked perfect, the project ID was correct, but every single call was rejected.This was all happening during a critical phase of development for a financial tool I was building, a gratuity calculation, click here to view. The pressure was on, and the authentication block was a complete showstopper.
Turns out, it was exactly what you mentioned: our server time had drifted by just a couple of minutes. It was the last thing I thought to check.
For anyone else pulling their hair out over this: seriously, check your server's clock sync! It's not always the credentials. Thanks for this clear breakdown.
