BREVO - Bad request - please check your parameters to is missing

Hi all !

I have spent hours trying to figure out an issue with my workflow.

I use Brevo to send email templates at the end of my workflow. However it keeps mentioning Bad request - please check your parameters to is missing**;
**
Recipients and parameters seem to be ok. I have an edit field previous to that node, wondering if this is where it is blocking

Anyone had that issue ? I’ve tried replacing the JSON with my email and it worked.
I’ve been able before to send email with a similar workflow but lost the modifications I made and starting from scratch again

Hi @Juliia ,

The “to is missing” error typically means the recipient email isn’t being passed correctly to the Brevo node.

Try this steps:

Step 1: Check Your Edit Fields Output

  • Execute the Edit Fields node

  • Look at the output data structure

  • Find the exact field name containing the email address

Step 2: Map It Correctly in Brevo
Once you know the field name, in your Brevo node’s “To” field:

  • Switch to Expression mode

  • Use: {{ $json.your_email_field_name }}

  • Replace your_email_field_name with the actual field name from Step 1
