Create a contact in Front when an email bounces in SendGrid

When an email bounces in SendGrid, create a contact in Front.

Start the 14-day trial, then find it under Templates → Library. It installs into the client you choose, switched off, with its checklist.

Every step, in order

When it happens in the first app, the step runs in the second, with the client’s own account.

An email bounces: An email bounced, within seconds. The API key needs Event Webhook access (Mail Send alone cannot make one), and each trigger uses one of the plan’s event webhooks.
Create a contact: A contact with an email handle.

Nothing. It needs only the accounts it connects to.

Each is the client’s own, stored encrypted and never copied between clients. Until one is added the client’s checklist shows it, and nothing runs.

SendGrid → Settings → API Keys → Create API Key with Mail Send access; for the triggers, also the Event Webhook settings permission (user.webhooks.event.settings.read and user.webhooks.event.settings.update), or Full Access. The From address must be a verified sender.
Front
In the client’s Front: Settings → Developers → API tokens → Create API token with the Shared resources namespace and the Read and Write permissions (Write for the contact step, Read for the triggers, which list events).

It lands switched off. The client’s checklist holds exactly this:

Get early access and you’ll be among the first in. Early members get a launch perk.
