update: I realized the reason was because the cloudant database was IAM only not IAM + Legacy which supports the username + password.
It would be good if the code was updated to support also the IAM only cloudant database offering, offering support for the IAM apikey + access token support as iam apikey alone can't authenticate against a cloudant database as stated from docs:
https://github.com/IBM/cloudant-python-sdk#iam-authentication
"You can't use an IAM API key directly to authenticate against IBM Cloudant." https://cloud.ibm.com/docs/Cloudant?topic=Cloudant-connecting
It would be great to see a implementation of IAM API key + Access token in a python app starter code
Just to clarify, while you can't use an IAM API key directly when using cURL (you must first get an IBM Cloud IAM token by using an API key) you can use the IAM API key to authenticate in our python-cloudant library.
There's an example of authenticating with IAM in our python-cloudant documentation.
@emlaver Thanks for clarifying that! That was it, that statement in the documentation caused alot of confusion. To further add to my wrong conclusions, starter kits all used legacy creds, led me to believe iam didn't work for apps and thought what a security risk!
This cleared it up and I used the code in the example you shared and successfully tested an app connection to the db. I was able to create, update using iam connection.
