Sales

When a customer buys, your shop tells Lekalao. Lekalao credits the sale to the last e-mail that could have caused it, and the campaign’s statistics show its revenue.

Report a sale

curl -X POST https://lekalao.example.com/api/v1/conversions \
  -H "Authorization: Bearer $LEKALAO_TOKEN" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -d '{
    "email": "ada@example.com",
    "amount": 12500,
    "currency": "XAF",
    "reference": "order-2026-00481",
    "occurred_at": "2026-09-17T10:14:00+01:00",
    "meta": { "channel": "online-shop" }
  }'

Field
`email`	The buyer. Required.
`list`	A list’s `id`, when the same address is on several. Otherwise the most recent subscription.
`amount`	An integer, in the smallest unit: `1250` is 12.50 €, `12500` is 12,500 FCFA.
`currency`	A three-letter code: `XAF`, `EUR`, `USD`…
`reference`	Your own order number. The same reference never counts twice.
`occurred_at`	When the sale happened. Now, by default.
`meta`	A free object, kept as it is.

Answer:

{
    "data": {
        "id": "a7f2…",
        "amount": 12500,
        "currency": "XAF",
        "reference": "order-2026-00481",
        "campaign": "0c9e3f5a-…",
        "attributed": true,
        "occurred_at": "2026-09-17T09:14:00+00:00"
    }
}

201 for a new sale; 200 when the reference already existed and the sale was updated. 404 when the address is on no list.

How a sale is credited

Among the e-mails sent to that person in the 14 days before the sale (the installation can change the window) and which they opened or clicked, Lekalao takes:

the one with the most clicks;
on a tie, the most recent one.

Campaigns and automation e-mails both count, A/B variants included. With no e-mail that fits, the sale is recorded with "attributed": false and counts for no campaign.

Refunds

curl -X DELETE https://lekalao.example.com/api/v1/conversions/a7f2… \
  -H "Authorization: Bearer $LEKALAO_TOKEN" -H "Accept: application/json"

The sale leaves the figures. For a partial refund, report the same reference again with the new amount.

Good habits

Report the sale once it is paid, from the server, not from the thank-you page a customer can reload.
Always send a reference: repeats and duplicates then inflate nothing.
Keep one currency per team if you want totals that read well.
