Unable to submit my collection for 15 days of postman for testers

Unable to submit my collection for 15 days of postman for testers i am getting errors

{
“error”: {
“name”: “AuthenticationError”,
“message”: “Invalid API Key. Every request requires a valid API Key to be sent.”
}
}

Can someone please help in detail how can I submit my work

Which day are you talking about?

Although its going to be a case of re-read the instructions. Which details how to authenticate.

Clue: x-api-header and postman_api_key

If you are talking about day 15, you need to fork the “secret” environment from the workspace where you forked all of the individual days\collections.
