SSL and API: is provider integration secure

1) What is an API in an online casino and why it is needed

API (Application Programming Interface) is a set of protocols and tools that allows online casinos to interact with game providers, payment systems, authentication systems and other external services.
Examples of casino API integrations:
  • Connecting slots, roulettes and live games from third-party providers.
  • Processing of payment transactions (deposits and withdrawals).
  • Verification of KYC documents and user verification.
  • Integration of analytical and CRM systems.

2) Role of SSL in API security

Traffic encryption: data transfer between the casino and the API provider is carried out via HTTPS with SSL/TLS, excluding the interception of logins, passwords, access tokens and game results.
Server authentication: SSL certificate ensures that the connection is established with the provider's server, and not with a fake resource.
Protection against MITM attacks: even if an intervention is attempted, traffic will remain encrypted.
Compatibility with OAuth2 and tokenization: SSL is the basic level of security when transferring authorization tokens.

3) Threats that SSL does not solve

Compromising an API key on the casino or provider side - an attacker can use the key without breaking the communication channel.
Errors in API logic - vulnerabilities in code can allow unauthorized access.
Insufficient validation of incoming data - the possibility of SQL injection, XSS or parameter spoofing.
Hacking accounts with API access rights - with weak authentication.

4) Additional API protection measures during integration

IP whitelists - access to the API only from certain casino servers.
JWT (JSON Web Tokens) - data signature for authentication.
HMAC request signatures - protection against data spoofing.
API versioning - eliminates outdated and vulnerable methods.
Rate limiting - limiting the number of requests for protection against DDoS and brute force.
Regular security audits - checking API for vulnerabilities.

5) How reliable casinos work

Use TLS 1. 3 and verified CAs only.
Mutual authentication (mutual TLS) is configured when both the casino and the provider have SSL certificates.
Multilevel authorization is used: API key + IP restriction + token.
Perform API load testing prior to start-up.

Conclusion:
  • SSL is a necessary, but not the only element of API protection when integrating gaming providers into online casinos. It guarantees encryption and connection authenticity, but complete security requires comprehensive measures: key management, access restriction, protection against code vulnerabilities and constant activity monitoring. Only a combination of these tools provides safe and stable integration.
