Slack alert when a client grants access

The moment Acme Co finishes your connect flow, a message lands in your #new-clients channel. About 5 minutes with Make.com — no code. (Prefer email? Step 5 has the one-module swap.)

Steps

1. In Make.com, create a new scenario and add a Webhooks → Custom webhook trigger. Click Copy address to clipboard.
   Hover to play
2. In ClientInvite, go to Settings → API & Webhooks, paste the URL, and click Save.
   Hover to play
3. Click Send test event. Back in Make, the webhook module now shows "Successfully determined" — it has learned the payload structure from the test event.
4. Add a Slack → Create a Message module after the webhook. Pick your channel (e.g. #new-clients).
5. In the Text field, map connectionSummaryText from the webhook module. That single field is the whole message — client name, email, and every connected account, already written out for you.
   Email instead: use a Gmail → Send an Email (or your provider's) module and map connectionSummaryHtml into the body.
   Hover to play
6. Click Run once, fire another test event, and check the channel. Then turn the scenario On.

The finished message

Level it up

• Add fields like status or customRef to the message — the field reference lists everything available.
• Next recipe: push the client into your CRM from the same webhook.
