Here is a quick summary of steps to take:

1. Create static connection to your API using "Authorization" header and format it like "Bearer XXXXX" (It seems you have done this already
2. Create function for like this for querying your token. 

(I am connecting to to PBI rest API in this example: https://login.microsoftonline.com/{{tenant id}}/oauth2/token)

Here is an example of this:

() =>

let

    body = "grant_type=client_credentials&scope=https://analysis.windows.net/powerbi/api/.default&client_id="&client_id&"&client_secret="&client_secret&"&resource="&resource,

    Data =Json.Document(Web.Contents("https://login.microsoftonline.com/"&tenant_id&"/oauth2/token",[Headers=[#"Content-Type"="application/x-www-form-urlencoded"],Content=Text.ToBinary(body)])),

    access_token = Data[access_token]

in

    access_token

 

Code explained:
1st We define what kind of body our request has 
2nd connecting to data using web.contents. Here important thing is Headers

3rd get token

Note: I am using parameters in my code for sensitive data. I recommend this for added security and dynamic options

3. Replace your static token used in step 1 with the function name. E.g. DynamicToken()

Here is an exellent video about this where instead of service principal login (like in my case) they are using username and password: https://youtu.be/N8qYRSqRz84
