Zapier

There is no published Evident app in the Zapier directory yet. You do not need one — Zapier’s built-in Webhooks by Zapier and Code by Zapier cover everything, and have done since day one.

Trigger: Catch Hook

1. In Zapier, create a Zap with Webhooks by Zapier → Catch Raw Hook as the trigger. Use Raw, not the parsed version — you need the exact bytes to verify the signature.
2. Copy the URL Zapier gives you.
3. In Evident, go to Settings → Webhooks, add it, and subscribe to the events you want.

Thirteen events are available across reviews, orders, gallery submissions and redemptions. See Outbound webhooks.

Verify the signature

Add a Code by Zapier step immediately after the trigger:

const crypto = require('crypto');

const expected = crypto
  .createHmac('sha256', inputData.secret)
  .update(inputData.rawBody)
  .digest('hex');

if (expected !== inputData.signature) {
  throw new Error('Bad signature');
}

output = [JSON.parse(inputData.rawBody)];

Pass the raw body, the x-evident-signature header and your webhook secret in as input fields. The endpoint is public by necessity, and the signature is the only thing separating a real event from someone who guessed the URL.

Action: Webhooks by Zapier

To write back to Evident, use Webhooks by Zapier → Custom Request against https://api.evidentugc.com/api/v1, with headers:

Authorization: Bearer evnt_YOUR_API_KEY
x-store-env-id: YOUR_STORE_ENV_ID

Both are required on every call. See Using the API.

MCP

Where Zapier offers MCP server connections, point one at:

https://mcp.evidentugc.com/mcp

with an Evident API key as the bearer token. That gives an AI step all twenty-two Evident tools at once instead of individual HTTP actions.

Zaps worth building

• Review below 3 stars → Slack. Ten minutes to build, and the single most useful thing most stores automate.
• One-star review → helpdesk ticket. Many are support issues in the wrong place.
• New photo review → content board. So your social team sees UGC as it arrives.
• redemption.created with fulfillment_status: unsupported → alert. The platform could not issue the discount; a human must.
• Weekly schedule → review analytics → email digest.

Reliability

Evident’s webhook delivery is fire-and-forget with a 15-second timeout and no automatic retry. Zapier’s Catch Hook responds fast on its own, which suits this well.

Deduplicate on event_id — it is stable across attempts, unlike x-evident-webhook-id, which is per HTTP attempt.

For anything you cannot afford to miss, add a scheduled Zap that reconciles against Evident’s event log rather than relying on delivery alone.
