1. Get an API key
An admin creates your venture and returns an API key once:api_key securely — only its hash is kept and it cannot be retrieved again.
2. Add a webhook endpoint (optional)
secret (shown once) used to verify signatures.
See Webhooks.
3. Create a payment link
payment_url.
4. Customer pays
On Satim’s hosted page, use a test card:
After payment, Satim redirects the customer back to Fintech Core, which confirms the
result, fires your webhook, and forwards the customer to your
success_url or fail_url.
5. Check the status
"status": "PAID". See Payments for refunds and the full status list.
