Is it possible to store AWS credentials: Access Key ID, Secret Access Key & Session Token in a file and have n8n load it instead of setting them via AWS S3 node UI ?
If yes: what should be the file content format, extension, name and path?
Hey @Gowthaman_Prabhu,
Node credentials most of the time would need to be set in the UI, Technically you could write a worfklow that reads and parses a local file and use expressions in the credentials to reference the values you read.
Out of interest why would you like to load them from a file rather than have them stored encrypted in a database?
@Jon Good point. Can I do the reverse then?. Save encrypted credentials in the DB myself? n8n can then read them if I use the same encryption key yes?
Hey @Gowthaman_Prabhu,
In theory you could manually write encrypted values to the database and it should read them but that would take a bit more work and I don’t have an example for that.
What I would do though is use the new API which has an option to add credentials to n8n.

@Jon Finally. Been waiting for the API 
. Are docs available too?
There should be docs in your n8n instance, if you go to settings there will be an option for API and that will give you a swagger interface you can play with.
