Webhooks faigh na himeachtaí sínithe i bhfíor-am

Comórtas

Tá an t-ábhar atá i `data` éagsúil ó ócáid go ócáid (táisc doiciméadúithe ag ócáid sa tagartha API). Seo sampla iomlán `envelope.completed`.

{
  "event": "envelope.completed",
  "envelope_id": "env_01HG3K8X9Y2N4P5Q6R7S8T9V0W",
  "occurred_at": "2026-05-27T08:42:13.521Z",
  "data": {
    "title": "Contrat de prestation Acme Corp",
    "status": "completed",
    "created_at": "2026-05-24T14:12:00.000Z",
    "completed_at": "2026-05-27T08:42:13.000Z",
    "signers": [
      {
        "email": "client@acme.example",
        "name": "Alex Client",
        "signed_at": "2026-05-27T08:42:13.000Z",
        "method": "eidas_aes",
        "ip": "203.0.113.42"
      }
    ],
    "proof_pdf_url": "https://certyneo.com/api/envelopes/env_01HG.../proof.pdf"
  }
}

Tá an t-ualach uimhriúil UTF-8 le BOM gan aon bhriathar. Tá síntiúis HMAC ríomh ar an gcorp amh mar a sheoltar ná déan athruithe ar na spásanna, athphársáil JSON déanann sé ord na eochracha a athrú go minic agus bristeann sé an fhíorú.

Déan seiceáil ar shíniú HMAC

Tá gach iarratais sínithe le do rún webhook (le feiceáil uair amháin nuair a chruthaítear iad sa dashboard, agus ansin cifrithe ag an am eile).<timestamp>,v1=<hex_hmac>`. Déan seiceáil i gcónaí ar an síniú sula ndéanann tú an t-ualach a phróiseáil gan an chéim seo, is féidir le duine ar bith imeacht a cheilt agus do chríochphointe a ghlaoch.

Beartas athchóirithe

Má fhreagraíonn do chríochcheantar rud éigin seachas HTTP 2xx (timeout, 5xx, connection refused), déanaimid bacóff exponential. Is é an líon iomlán 6 iarracht in ~9 uair an chloig. Tar éis na 6 uair, marcáiltear an ócáid `failed` i do dhátachlár gréasáin agus seoltar ríomhphost rabhaidh.

Más mian leat imeacht a chaillte a chur ar aghaidh de láimh, cuireann an dashboard webhook cnaipe Ath-sheachadadh ar fáil ar gach seachadadh a chaill ar fáil ar feadh 7 lá tar éis an easpa deiridh.

Bain triail as gan fíor-chúlpach a sheoladh

Is é an pointe deiridh `/v1/webhooks/test` a ghlacann le URL agus cineál imeachta, agus POSTe payload ficseanúil sínithe díreach mar fíor.

# Trigger a test webhook to your endpoint
curl -X POST https://api.certyneo.com/v1/webhooks/test \
  -H "Authorization: Bearer $CERTYNEO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"event": "envelope.completed", "url": "https://your.app/webhooks/certyneo"}'
