Authentication/Browser Problem when deployed. about heroku-buildpack-r HOT 7 CLOSED

Hi @gbultman

The simple answer is that when your application is deployed and run on Heroku, it's then running on the server side, which is headless, and therefore cannot run a browser or any user interface for that matter.

What is the OAuth2 token used for? Is it so that your R code can consume a 3rd party service?

Thanks for the prompt reply, Chris. Yeah. Specifically, Hubspot CRM data. Should I be looking into your docker solution? I'm pretty new to the web deployment side of things, but pretty familiar with R. RServer looks good but then I'd have to ditch Heroku, I think.

The easiest way around this would be to use a Hubspot API key instead of using OAuth2 to authenticate.

You will need to generate/retrieve the Hubspot API key and then change your app to use it to authenticate instead of using the OAuth method. Use an environment variable to "pass through" the key from the host to your R code, such as:

hubspotApiKey <- Sys.getenv('HUBSPOT_API_KEY')

# code to instantiate Hubspot client, providing hubspotApiKey...

Then configure your app's environment variables on Heroku to include the API key. This way the code is the same for both local and deployed scenarios.

Alternatively, if you intend for you application to be used by other people, and have it connect to their Hubspot accounts, then you will need to implement the Authorization Code Flow, which is quite a bit more involved to implement.

... and, in this example the docker version of the buildpack would need to be implemented in much the same way. I.e. It also runs headless, so won't have access to the browser on the server side.

Hi @gbultman
Did you manage to get it working?

from heroku-buildpack-r.

I did. I ended up just saving the token in the root directory. Right now, it is doing stale refreshes, but I plan on just getting a service token. I was able to use that for manipulating things on my google drive - saving data etc. It's not ideal, but it works for now.

Thanks for your help.

Okay thanks. I'll close the issue.
