Octopus Agile -registering on the Fox App

There is an option under work mode for Octopus Agile. I am trying to register but not clear what the first field is. It is title "Number" and the information button description is "registered number of the business".
Asking Fox AI it suggested this was the MPAN
However having entered MPAN and API key I get an error message "Code 40256, please close and reopen this page"?
Any advice appreciated Thanks

Hi there. I have tried entering my Agile account (starts with A-) and my Octopus API key in the relevant fields on the app and website. On both, I get an error - invalid number or API key.

I have Octopus Agile.

Any idea if i am doing something wrong or if there is a bug with this integration?

If you’ve just opened your agile account it can take a couple of weeks for Octopus to get everything settled. If you’re a long term user then it’s something else, it may be worth downloading another app, like EnErgy Stats or Octo-Aid (iOS) to see if the API works on those. If it works on one it should work on all.

Here is a post from a long time ago, it shows the values entered, and what it looks like if successful.

I would say that sometimes a copy and paste can go wrong, there maybe a hidden space at the end of the string when pasted in, so perhaps erase the last character and type it back in manually.
