Nifi API - 403 error

[#1]

I am running nifi locally using docker, I tried to generate token using the following url and obtained token successfully

https://localhost:8443/nifi-api/access/token

but when I tried to make POST call to the following URL, I received 403 error code. I used same token generated with above request, can anyone suggest what am I doing wrong?

https://localhost:8443/nifi-api/process-groups/d9a891ee-017e-1000-4067-96bceee7d5e3/template-instanc...

@Chhavi ,

Please try this:

curl -X POST \
  -H 'Content-Type: application/x-www-form-urlencoded' \
  -d 'username=bob&password=supersecret1' \
  "https://nifi-1.example.org:8443/nifi-api/access/token"

Regards,

André

I was facing the same response using postman and getting a 403 when calling the REST API endpoints at: https://nifi.apache.org/docs/nifi-docs/rest-api/index.html

I received the token, and by default put a prefix of Bearer in front. This is not required. Now, hitting any of the GET endpoints results in a positive response.

Unfortunately there is no way at the moment of uploading templates. If there is no REST endpoint for this, how can this be done via automated pipelines?

Thank you

@Kushisabishii ,

Which version of NiFi are you using?

There's an API endpoint for this: POST /process-groups/{id}/templates/upload

Cheers,

André

Thank you for the really quick response @araujo! I'm using the latest docker container available.

I'm new to Nifi so still working this through...

So I would have to first create a process group with: POST /process-groups/{id}/process-groups and then follow your instructions above.

Much appreciated!

You can get the id of the root process group and import the template there as well.
