> Key: NIFI-6078
> URL: https://issues.apache.org/jira/browse/NIFI-6078
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: Peter Turcsanyi
> Assignee: Peter Turcsanyi
> Priority: Major

>
> Implement a new PostSlack processor which is able to upload and attach the
> FlowFile content (eg. an image) to the Slack message.
> The current PutSlack processor uses Slack Webhooks which have some
> limitations:
> - file uploading not supported, only text messages (which can contain
> attachment links, but not the file to be uploaded itself)
> - the current version of Slack Webhooks do not support the runtime
> configuration of Channel, Username, etc, parameters any more, so these
> properties of PutSlack have no effect
> To overcome these limitations, the Slack Web API needs to be used instead of
> Webhooks. Due to this technology change, it is better to reimplement the
> functionality in a new processor than extending the existing one.
