Help with Google Account

[ISLAGAD]

hello!!
Sorry, this is the first time I open a discussion here.
I'm not a programmer or anything.
They made me an APP with a Google My Business API, but I don't know which Gmail account was created.

I have this data:
public $googlePlacesApiKey

and

public $knowledgeGraphKey

I know the easiest thing would be to ask the developers, but they don't know, they don't remember, or they don't want to tell me.
What I can do?
How can I know the account?

I have many, many Gmail accounts and I really don't know if it's mine or the developers' and they don't want to give it to me.

Sorry if this doesn't go here, please move it or whatever is pertinent if this is not the place.

I understand your frustration. Since you don't have direct access to the developers, there are a few things you can try to identify the associated Gmail account:

Check Your Gmail Accounts:

• Carefully review the sent mail and activity logs of your Gmail accounts. Look for any emails or notifications related to Google My Business, Google Cloud Platform, or API key creation.
• Log into each Gmail account and visit the Google Cloud Console (https://console.cloud.google.com/). Check if any of your accounts have projects associated with the Google My Business API.

Contact Google Support:

• Reach out to Google Cloud Platform support and provide them with the googlePlacesApiKey and knowledgeGraphKey. Explain your situation and ask if they can help you identify the associated Gmail account. They might be able to assist you if you can provide enough information to prove your ownership of the app.
