Tip for sharing information

Pasting your n8n workflow

Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.

```
<your workflow>
```

That implies to any JSON output you would like to share with us.

Make sure that you have removed any sensitive information from your workflow and include dummy or pinned data with it!

Here’s an example of using external modules

const { createHmac } = require('crypto');
const moment         = require('moment');

const secret = 'abcdefg';
const hash = createHmac('sha256', secret)
               .update('I love cupcakes')
               .digest('hex');

const d = moment().subtract(10, 'days').calendar();

return { hash, d };

If you are self-hosting, you would list the modules you want to use with environmental variables as per Enable modules in Code node | n8n Docs.
