SK Sign Developers Portal — Quickstart, APIs, and Webhooks

Quickstart Integration

Initiate actions securely in three simple steps. Authenticate requests using Platform-signed delegated JWT tokens.

$ curl -X POST https://api.softknack.com/v1/sign \
  -H "Authorization: Bearer <delegated_JWT>" \
  -H "Content-Type: application/json" \
  -d '{"org_id": "org_01"}'

import axios from 'axios';

const response = await axios.post('https://api.softknack.com/v1/sign', {
  org_id: 'org_01'
}, {
  headers: { Authorization: 'Bearer <delegated_JWT>' }
});

import requests

response = requests.post(
    'https://api.softknack.com/v1/sign',
    json={"org_id": "org_01"},
    headers={"Authorization": "Bearer <delegated_JWT>"}
)
