Ecwid Integration

Accept USDC on Algorand and aUSDC on VOI as payment in your Ecwid store via AlgoVoi.

How it works

Customer places an Ecwid order
            ↓
Ecwid fires a webhook (new_order event)
            ↓
AlgoVoi verifies HMAC-SHA256 signature → parses order
            ↓
AlgoVoi creates a hosted checkout link (USDC or aUSDC)
            ↓
Customer pays on-chain
            ↓
AlgoVoi verifies the transaction on-chain
            ↓
Ecwid order marked as paid with TX ID in order comments

Prerequisites

• An active AlgoVoi tenant account
• An Ecwid store on Business plan or higher (required for the Ecwid REST API and webhooks)
• An Ecwid Store ID and Secret Token (from the Ecwid control panel)

---

Step 1 — Configure your network

USDC on Algorand mainnet

POST /internal/tenants/{tenant_id}/network-configs
Authorization: Bearer <admin-key>
Content-Type: application/json

{
  "network": "algorand_mainnet",
  "payout_address": "<your-algorand-address>",
  "preferred_asset_id": "31566704",
  "preferred_asset_decimals": 6
}

aUSDC on VOI mainnet

POST /internal/tenants/{tenant_id}/network-configs
Authorization: Bearer <admin-key>
Content-Type: application/json

{
  "network": "voi_mainnet",
  "payout_address": "<your-voi-address>",
  "preferred_asset_id": "302190",
  "preferred_asset_decimals": 6
}

---

Step 2 — Get your Ecwid API credentials

1. In your Ecwid control panel go to Apps → My Apps → Ecwid API
2. Note your Store ID
3. Copy your Secret Token (used for both API calls and webhook signing)

Alternatively, create a custom app at developers.ecwid.com and complete the OAuth flow to obtain a token with read_store_profile read_orders update_orders scopes.

---

Step 3 — Connect the integration

POST /internal/integrations/{tenant_id}/ecwid
Authorization: Bearer <admin-key>
Content-Type: application/json

{
  "credentials": {
    "store_id": "<ecwid-store-id>",
    "secret_token": "<ecwid-secret-token>"
  },
  "shop_identifier": "<ecwid-store-id>",
  "base_currency": "USD",
  "preferred_network": "algorand_mainnet"
}

The response includes a webhook_secret and a webhook_url.

---

Step 4 — Register the webhook

Register your AlgoVoi endpoint via the Ecwid REST API:

POST https://app.ecwid.com/api/v3/{store_id}/webhooks
Authorization: Bearer <secret_token>
Content-Type: application/json

{
  "url": "<webhook_url from Step 3>",
  "event": "order.created",
  "secret": "<webhook_secret from Step 3>"
}

Ecwid signs webhook requests with HMAC-SHA256. The signature is in the X-Ecwid-Webhook-Signature header (base64-encoded).

---

Payment flow for your customers

Once connected, every new Ecwid order triggers AlgoVoi to:

1. Create a hosted checkout link valid for 30 minutes
2. Display the USDC (or aUSDC) amount with a QR code and wallet link
3. On successful on-chain confirmation:
   • Ecwid order payment status set to PAID
   • TX ID added as a private order comment

---

Troubleshooting

Symptom	Likely cause
HTTP 401 on webhook	Signature mismatch — check webhook_secret matches the secret used at registration
HTTP 422 "No network config"	Network config missing for preferred_network
Order not updating	Token lacks update_orders scope or has expired
Webhook not firing	Ecwid Business plan required; check app webhook registration
