Go to Production

Before going live, run through this checklist to ensure a smooth production launch.

1. Use the production base URL

Switch from testnet to mainnet:

https://api.ipint.io:8003

2. Use production API credentials

• Do not use demo/test API credentials in production.
• Use the final production API key and secret sent to your registered email.
• Keep these as secure as private keys or passwords.
• Never share your API secret in any request — use it only to generate the HMAC signature. See Authentication.

3. Complete testnet testing

Before moving to production, make sure you've tested thoroughly on testnet:

• Redirection to your merchant_website after payment completes
• You receive callback requests on your invoice_callback_url
• You call GET /invoice after each callback to verify status
• You receive email notifications for completed/failed transactions
• Your users receive email notifications for PROCESSING and COMPLETED statuses

4. Use unique user IDs

Pass a unique user_id for every unique user when calling /checkout. This helps with tracking, reconciliation, and analytics.

5. Check minimum and maximum amounts

Each cryptocurrency has minimum and maximum deposit amounts. Check these via GET /prices before creating invoices, and validate on your end to avoid rejected payments.

6. Compare invoice vs received amounts

Invoice amount = what the user enters to pay. Received amount = what they actually paid. Sometimes invoices are underpaid or overpaid.

Before giving credit, compare:

• invoice_amount_in_local_currency vs received_amount_in_local_currency
• invoice_amount_in_usd vs received_amount_in_usd
• invoice_crypto_amount vs received_crypto_amount

7. Keep supported currencies updated

If you show supported currencies on your website, fetch the updated list from:

https://api.ipint.io:8003/currencies

Cache the response with a TTL (e.g. 1 hour) to avoid rate limits.

8. Show a demo to the iPint team

When your integration is complete and tested, it's recommended to show a demo to the iPint team before going live. Contact help@ipint.io to schedule.

Production checklist

• Base URL changed to https://api.ipint.io:8003
• Production API key and secret in use (not test credentials)
• HMAC signature working correctly
• merchant_website redirect tested
• Webhook (invoice_callback_url) receiving callbacks
• GET /invoice verification working after each callback
• Unique user_id per customer
• Min/max amount validation
• Invoice vs received amount comparison
• Currency list cached and updated
• Demo shown to iPint team

Next steps

• Testing on Testnet — if you haven't tested yet
• Authentication — HMAC signature details
• Webhooks — callback handling
