Onboarding Steps

Follow these five steps to complete your first stablecoin collection from scratch.

1. Become a Paydify partner

Contact our business team to complete KYC and obtain your identifiers:

• PartnerID (PID) — your unique identity on Paydify; sales and operations serve you by PID.
• MerchantID (MID) — the merchant entity that originates transactions; you may have multiple MIDs. PID and MID are currently provisioned by your BD.

2. Confirm your business scenario

Clarify which product capabilities you need — Payin, Payout, or Custodian treasury:

• Each product exposes a different API set; your BD confirms this during KYC.
• See solution overview for scenario fit and examples.

3. Receive sandbox credentials

After KYC, Paydify sends sandbox credentials to your registered email:

• x-api-key is paired with x-api-secret, used for request signing and verification.

4. Create your first API request

POST /payin/v1/createPayment

A Minimal Viable Integration needs only four actions:

1. Sign and call POST /payin/v1/createPayment with sandbox x-api-key + x-api-secret;
2. Open the returned httplink in a browser and jump to the selected wallet to pay;
3. Listen for async callbacks on notificationUrl;
4. When callback state = PAID, call getPaymentStatus to confirm.

See CKP checkout integration for fields, signing, and callbacks.

5. Go live in production

After sandbox integration is complete, submit to your BD:

• Sandbox test report;
• Outbound IP allowlist for callbacks;
• Proof of valid HTTPS certificate on your callback domain (required in production).
