Help Request - Workaround Import String Length, Character Limit

Hello, I'm currently working a v2 REST API that requires an expiring access token in the other API requests. Therefore, I need to parameterize my Access token and call it in the other queries that request data from the API. 

 

I was successfully able to target the token and parameterize it, however, when the other queries were failing to authenticate I realized that on import, the Access Token was being truncated form around 1400 characters to 1024 including the 3 ellipses that it added to denote truncation. 

 

I am hoping to find a work around to this character limit as my team are so close to finish this phase of the project and do not want to be held up by as something as simple as a string character limit. If you have any way of getting around this limit please let me know, I will take any recommendations and test them.

I was able to solve the issue by putting {0} at the end of my formula bar once the value was isolated into a list with a single value. 

It then became targetable in separate power query editors.
