CashEnvoy is one of Nigeria's earliest payment gateways, operated by E-Settlement Limited (ESL) and regulated by the Central Bank of Nigeria. The platform enables Nigerian merchants to accept online payments from customers using Nigerian debit cards (Verve, Visa, Mastercard), international cards, and the CashEnvoy wallet. The company claims to have processed over 10 million transactions and serves 5,000+ active merchants. What the API Does The CashEnvoy API enables developers to integrate payment processing into websites and applications, accepting NGN and USD transactions. Core capabilities include card payment acceptance (Verve, Visa, Mastercard), CashEnvoy wallet payments, and multi-currency support. The integration process is described as developer-friendly with API documentation provided through the merchant portal. How Developers Use It Developers create a merchant account at cashenvoy.com, obtain API keys from the dashboard, and integrate using the provided documentation. Authentication is via API key from the merchant dashboard. The API enables payment initiation, transaction verification, and merchant settlement processing. Pricing CashEnvoy does not publish its transaction fees publicly. As a CBN-regulated payment gateway, fees are likely in line with Nigerian payment industry standards. Contact CashEnvoy directly for current fee schedules. Compliance CashEnvoy is regulated by the Central Bank of Nigeria (CBN), which means it must comply with Nigerian payment system regulations, PCI-DSS standards for card processing, and merchant onboarding requirements including KYC for businesses. Challenges and Gotchas Important considerations: (1) CashEnvoy has a reported headcount of 1 employee as of early 2026 — this raises legitimate concerns about support responsiveness, active development, and long-term platform viability. (2) The platform is functional but far less actively developed than Paystack or Flutterwave. (3) API documentation is limited and not publicly accessible without account creation. (4) No support for newer payment methods like bank transfer checkout, USSD, or crypto. (5) Developers should carefully evaluate support SLAs and integration longevity before choosing CashEnvoy over more actively maintained alternatives. Company Background CashEnvoy was founded as one of Nigeria's early digital payment platforms and is operated by E-Settlement Limited. It was a notable player in the early Nigerian fintech ecosystem, predating the Paystack era. While the platform remains operational, it has not kept pace with the growth and feature velocity of newer Nigerian payment gateways. FAQs Q: Is CashEnvoy still active in 2026? A: The website is live and the API appears functional. However, the company reportedly has a very small team which may affect support and future development. Q: Does CashEnvoy accept Verve cards? A: Yes. CashEnvoy accepts Nigerian debit cards including Verve, Visa, and Mastercard. Q: What currencies does CashEnvoy support? A: NGN (Nigerian Naira) and USD are supported. Q: Should I use CashEnvoy for a new project? A: For new projects, consider Paystack or Flutterwave as primary options given their active developer ecosystems, robust documentation, and larger support teams. CashEnvoy may be suitable as a fallback or for specific existing integrations.
GTPay is the online payment gateway from Guaranty Trust Bank (now Guaranty Trust Holding Company — GTCo), one of Nigeria's largest and most recognized tier-1 banks. GTPay enables Nigerian merchants to accept card payments online from customers using Interswitch (Verve), Visa, and Mastercard — both locally issued and international cards. The gateway is backed by GTBank's banking infrastructure and has been serving Nigerian e-commerce merchants since the early days of online payments in Nigeria. What GTPay Does GTPay processes card-present-not-required (CNP) transactions for online merchants, collecting payment from customers and settling into the merchant's GTBank business account. The gateway supports NGN (currency code 566) and USD (currency code 840) transactions, making it usable for both local NGN e-commerce and international USD billing. How Developers Use It Developers obtain a Merchant ID and Hash Key by physically visiting any GTBank branch nationwide and registering as a GTPay merchant. After registration, integration is done using the technical parameters documented at ibank.gtbank.com/gtpay/IntegrationAPI/mman-tech.html. Key parameters include: gtpay_mert_id (merchant identifier), gtpay_tranx_id (unique transaction ID from merchant), gtpay_tranx_amt (amount in kobo or cents), and gtpay_tranx_curr (ISO currency code — 566 for NGN, 840 for USD). The Hash Key is used to generate a transaction hash for request signing. Pricing Local card transactions: 1.5% fee capped at ₦2,000. Contact GTBank for the full fee schedule including international card rates. Authentication Merchant ID and Hash Key pair obtained from GTBank branch. Transactions are signed using the Hash Key to generate a security hash that GTBank validates before processing. Compliance GTPay is operated by Guaranty Trust Bank (CBN-licensed), ensuring full CBN compliance for all payment processing. PCI DSS compliant for card data handling. Important Note on Legacy Status GTCo (formerly GTBank) has since launched Squad (squadco.com) as their modern, developer-first payment platform under HabariPay Limited. Squad offers a comprehensive REST API with sandbox, webhooks, virtual accounts, and full documentation. For new integrations, Squad is the recommended modern alternative to GTPay. GTPay remains operational for existing merchants. Challenges and Gotchas (1) Merchant registration requires a physical GTBank branch visit — not self-serve online. (2) GTPay is a legacy product — documentation is older and less comprehensive than modern gateways. (3) No bank transfer, USSD, or recurring billing support. (4) Integration is form-post based rather than modern REST JSON API. (5) New projects should seriously consider Squad (HabariPay) instead. FAQs Q: How do I get a GTPay Merchant ID? A: Visit any GTBank branch nationwide with your business documents to register as a GTPay merchant. Q: Is GTPay still active? A: Yes, GTPay remains operational for existing merchants but GTCo's newer platform Squad is the recommended modern alternative. Q: Does GTPay support USSD or bank transfer? A: No. GTPay only supports card payments (Interswitch/Verve, Visa, Mastercard). Q: What currencies does GTPay support? A: NGN (566) and USD (840).
