Chain query execution

[Markzolotoy]

I have one query that generates  a secret key. Another query uses that key to get  a token. After the secret key is provided to the backend it gets invalidated and new key needs to be created. So, how can I execute first query and use its results for the second query?

Thanks

Yes, that should work, but what about a situation when I might have a number of data sources that all need a token to get data? I dont want to request a token every time data is pulled. I need to store it somehow and reuse it.

Hi @Markzolotoy 

In the 2nd query that uses the key, make a test request to your API, check for an error in the response that indicates the key is invalid.

If it is invalid then call the first query to generate a new key.
