Pull data fromAPI with token from multiple query, each one invalidate each other's token

For clarity, I will write the full solution here

 aj1973 provided a clue to get to my solution. in this link https://www.youtube.com/watch?v=2RZkc_qrV1g&t=610s

What I need was :

• get a access_token to be generated once and stored in order to be used by the other queries.
• do not expose that token outside of those queries

What I could not do :

• have a function that request the token and call that function in each subsequent queries because each call would generate a new accesstoken and invalidate the previous one.

Solution : 

• create a queries that results in a 1 row, 1 column table with the accesstoken.
• Uncheck the "enable load" on that query 
  • 

  •  this prevent this token to be accessible outside the queries and will not be accessible by anyone consulting the resulting data

  • Doesn't required premium, if you leave it check, it will be consider a premium feature
• Then in each of the query that needs that token, you can get that token like this: Table.FirstValue(get_tokenQuery)
  Each time a query ask for that value from that table, if that table is empty, the get_tokenQuery will run and then return the result, if the get_tokenQuery has already ran, it will simply return the token but will not generate a new token. Thus all the query can run simultaneously with the same token

Success.
