Webhook for new replies isn't posting to my Slack channel

#63 In Progress

Set up a webhook to post new replies into a Slack channel via an incoming webhook URL. Nothing's showing up in Slack even though replies are coming in fine on our end.

Can you check Settings > API & Webhooks > Delivery Log for that webhook? It'll show every attempt along with the HTTP status code Slack returned. If it shows a non-200 response, that tells us where to look — Slack incoming webhooks are picky about payload format (they expect a specific JSON shape with a text field at minimum).

Log shows a bunch of 400 responses. So probably a payload format issue like you said.

Yep — our default webhook payload is our own event schema, not pre-formatted for Slack's expected structure. You'll need a small transform step in between (Zapier or a lightweight serverless function works well) that reshapes our payload into a plain {"text": "..."} body before forwarding to the Slack incoming webhook URL. Posting straight from our webhook to Slack's URL without that transform is what's causing the 400s.
