Merso Integrationv1.0.5

A mobile game developer wants to offer installment payments for virtual currency packs, allowing players to buy now and pay later without credit checks. This scenario involves setting up the Merso API, handling webhooks for payment status, and ensuring idempotent item delivery.

An NFT marketplace integrates Merso to enable users to purchase NFTs with installment plans. The integration requires unique itemId generation per transaction, webhook registration, and fallback verification to handle cases where webhooks are delayed.

A developer faces issues where webhook events are not triggering item delivery. They need to check idempotency handling, verify the webhook URL is correctly registered, and implement the GET /verify-payment-intent endpoint as a fallback.

A business development representative uses the commercial reference to present case studies showing higher GMV and conversion rates with Merso, highlighting zero KYC and credit risk for merchants.

A developer building a web store for digital assets (e.g., software licenses) integrates Merso payments. They configure Node.js with env vars, implement the buy endpoint with unique itemId, and apply TLS SNI when behind Cloudflare.

Merso charges a fee for each installment transaction, typically a percentage of the total sale. Merchants can offer higher-priced items with installment plans, increasing average order value.

Merchants pay a monthly subscription for advanced features like custom webhook handling, priority support, or higher API rate limits. This model is suitable for high-volume game studios.

Basic integration is free, but Merso takes a revenue share on each transaction. Merchants can upgrade to a flat-fee model if transaction volume exceeds a threshold.
