Very much a newbie to this so open to any resources that can help. 

 

I'm trying to build a custom connector to Constant Contact v3 API. 

 

For whatever reason the API does not accept "." in the parameters. Power Automate is converting ":" and "/" but no others in the request. Full stops are present in the redirect and state parameters of the request.

 

I've reached out to Constant Contact support and they've stated that the below are accepted: 

  • Alphanumeric
  • Comma
  • Underscore
  • Hyphen

Is this something I can achieve in Power Automate or is it back to the drawing board. 

 

Much appreciated,
